The genus Adonis L. (Ranunculaceae), native to Europe and Asia, comprises 32 annual or perennial herbaceous species. Due to their cardiac-enhancing effects, Adonis spp. have long been used in European and Chinese folk medicine. These plants have been widely investigated since the late 19th century, when the cardiovascular activity of Adonis vernalis L. was noted in Europe. The present paper provides a review of the phytochemistry, biological activities and toxicology in order to highlight the future prospects of the genus. More than 120 chemical compounds have been isolated, with the most important components being cardiac glycosides as well as flavones, carotenoids, coumarins and other structural types. Plants of the genus, especially A. vernalis L. and A. amurensis Regel & Radde, their extracts and their active constituents possess broad pharmacological properties, including cardiovascular, antiangiogenic, antibacterial, antioxidant, anti-inflammatory and acaricidal activities, and exhibit both diuretic effects and effects on the central nervous system. However, most plants within the 32 species have not been comprehensively studied, and further clinical evaluation of their cardiovascular activity and toxicity should be conducted after addressing the problem of the rapidly decreasing resources. This review provides new insight into the genus and lays a solid foundation for further development of Adonis.
<i>Codonopsis</i>, in the family Campanulaceae, is a genus containing 42 species of dicotyledonous herbaceous perennial plants, predominantly found in Central, East and South Asia. Several <i>Codonopsis</i> species are widely used in traditional medicine and are considered to have multiple medicinal properties. Among the <i>Codonopsis</i> species, <i>Codonopsis pilosula</i> (Franch.) Nannf. and <i>C. lanceolata</i> (Sieb. et Zucc.) Benth. & Hook. f. ex Trautv. are more popular than others according to the findings, especially phytochemical and bioactive studies. Phytochemical research shows that <i>Codonopsis</i> species contain mainly polyacetylenes, phenylpropanoids, alkaloids, triterpenoids and polysaccharides, which contribute to multiple bioactivities. However, the mechanisms of their bioactivities need to be further elucidated. The less popular <i>Codonopsis</i> species remain to be studied and exploited. In addition, although a series of methods for the quality evaluation of <i>Codonopsis</i> species have been developed, a feasible and reliable approach to the efficacious and safe use of various <i>Codonopsis</i> species is still needed, with considering botanical origin, chemical constituents and bioactive effects. This review aims to provide up-to-date and comprehensive information on the phytochemistry, bioactivity and quality control of medicinal plants in the genus <i>Codonopsis</i> and to highlight current gaps in knowledge, which is useful for the wider development of the <i>Codonopsis</i> genus.
BACKGROUND: Studies indicate that the incidence of disease, the mortality rate, and medical costs are significantly higher in people aged 65 years and over who do not engage in physical activities than in their peers who do engage in these activities. Therefore, promoting appropriate physical activity among older adults in the community is essential to delaying the health implications of aging. PURPOSE: This pilot test was developed to assess the effectiveness of a newly developed Senior Elastic Band (SEB) exercise program on the health of older adults in community care stations. METHODS: A quasiexperimental design was used. A convenience sample of 20 participants from a community care station was recruited. The SEB intervention included three phases (warm-up, aerobic motion, and static stretching) and was conducted three times per week, 40 minutes per session for 1 month. Twelve health indicators in three categories (functional fitness, self-perceived health status, and sleep quality) were examined before and immediately after 1 month of SEB exercises. RESULTS: Participants showed improved performance at the end of the 1-month study for the following indicators: lung capacity, cardiopulmonary fitness, upper and lower body flexibilities, upper limb muscle power, lower limb muscle endurance, and self-perceived physical health status (all ps < .05). No significant differences were identified for the other indicators. CONCLUSIONS/IMPLICATIONS FOR PRACTICE: The SEB exercise program shows preliminary and promising effects on improving the health of older adults in a community care station. Healthcare professionals who work with older adults living in the community may consider the SEB exercise program as a health promotion modality to recommend and implement with this population. However, we recommend further testing the long-term effects of this program on a larger population.
Abstract Ethnopharmacological relevance Herpetospermum caudigerum Wall. (HCW) is a traditional Tibetan medicine, which has been used to ameliorate liver injuries in the folk. Aim of the study Liver fibrosis has been recognized as a major lesion of the liver that leads to liver cirrhosis/hepatocarcinoma and even to death in the end. This study aims to demonstrate the protective effect of HCW against CCl 4 -induced liver injury in rats and to explore the underlying mechanisms. Materials and methods Hepatic fibrosis was induced by intraperitoneal injection of CCl 4. Liver function markers, fibrosis markers, serum anti-oxidation enzymes as well as elements levels were determined. Serum and liver tissues were subjected to NMR-based metabolomics and multivariate statistical analysis. Results HCW could significantly reduce the elevated levels of fibrosis markers such as hyaluronidase, laminin, Type III procollagen and Type IV collagen in the serum, improve the activities of the antioxidant enzymes, and effectively reverse the abnormal levels of elements in liver fibrosis rats. Correlation network analysis revealed that HCW could treat liver fibrosis by ameliorating oxidative stress, repairing the impaired energy metabolisms and reversing the disturbed amino acids and nucleic acids metabolisms. Conclusion This integrated metabolomics approach confirmed the validity of the traditional use of HCW in the treatment of liber fibrosis, providing new insights into the underlying mechanisms.

The extraction and solvent partition of roots of <i>Incarvillea compacta</i>, a traditional Tibetan folk medicine, and repeated column chromatography and preparative high-performance liquid chromatography for <i>n</i>-butanol fraction yielded four phenylethanoid glycosides, crenatoside (<i>1</i>), 3′′′-<i>O</i>-methylcrenatoside (<i>2</i>), leucoseceptoside A (<i>3</i>), and martynoside (<i>4</i>). The chemical structures were identified on the basis of spectroscopic data analyses including NMR and MS. All compounds were isolated for the first time from the plant. Compound <i>1</i> exerted better 1,1-diphenyl-2-picrylhydrazyl free radical scavenging activity. In addition, compounds <i>1</i>-<i>4</i> were evaluated for their hepatoprotective activity on carbon tetrachloride (CCl<sub>4</sub>)-induced liver injury in HepG2 cells. Pretreatment of HepG2 cells with compound <i>1</i>-<i>4</i> significantly increased the viability on CCl<sub>4</sub>-induced cell death. Furthermore, compounds <i>1</i>-<i>4</i> also alleviated CCl<sub>4</sub>-induced hepatotoxicity by enhancement of the antioxidant enzyme activities of superoxide dismutase and reduction of the malondialdehyde content, intracellular ROS as well as NF-κB transactivation. Our results suggest that phenylethanoid glycosides ameliorate CCl<sub>4</sub>-induced cell injury, and this protection was likely due to antioxidative activity and down-regulation of NF-κB.

Although when the BBB are got damaged by neurodegenerative disorders, the absorbed HgCl2, mainly in form of Hg (II)-serum albumin adduct (Hg-HSA) in human plasma, can penetrate BBB and affect central nervous system (CNS) cells. Current study planned to evaluate the effect of Hg-HSA on the physiological function of N9 microglial cells. At low dosage (15 ng/mL) of Hg-HAS, the observed outcomes was: promoted cell propagation, Nitric Oxide (NO) and intracellular Ca2+ levels enhancement, suppressed the release of TNF-α and IL-1β and inhibited cell proliferation. At high dosage (15 μg/mL) we observed decline in NO and intracellular Ca2+ levels, and increment in the release of TNF-α and IL-1β. These biphasic effects are similar to hormesis, and the hormesis, in this case, was executed through ERK/MAPKs and JAK/STAT3 signaling pathways. Study of quantum chemistry revealed that Hg2+ could form stable coordination structures in both Asp249 and Cys34 sites of HSA. Although five-coordination structure in Asp249 site is more stable than four-coordination structure in Cys34 site but four-coordination structure is formed easily in-<b>vivo</b> in consideration of binding-site position in spatial structure of HSA.
Methylmercury (MeHg+) is an extremely toxic organomercury cation that can induce severe neurological damage. Once it enters the body, methylmercury binds to amino acids or proteins containing free sulfhydryl groups. In particular, methylmercury is known to bind with human serum albumin (HSA) in human plasma; however, the effects of methylmercury-HSA conjugate (MeHg-HSA) on the central nervous system (CNS) are not fully understood. In the present study, we used the microglial cell line N9 as the target cells to evaluate the effect of MeHg-HSA on physiological function of the CNS preliminarily. The various factors in the cell culture were monitored by MTT assay, total lactate dehydrogenase assay, ELISA, qPCR, Western blot and flow cytometry techniques. The results showed that low-dose treatment with MeHg-HSA activated N9 cells, promoting cell proliferation and total cell number, enhancing NO and intracellular Ca2+ levels, and suppressing the release of TNFα and IL1β without cytotoxic effects; while high-dose MeHg-HSA exhibited cytotoxic effects on N9 cells, including promoting cell death and increasing the secretion of TNFα and IL1β. These results indicate that MeHg-HSA causes hormesis in microglia N9 cells. Furthermore, ERK/MAPKs and STAT3 signaling pathways related to the hormesis of MeHg-HSA on N9 cells. In addition, low dose of MeHg-HSA might be viewed as something very close to a lowest observed adverse effect level (LOAEL) for N9 cells. These findings will be useful for investigating the hormesis mechanism of MeHg+ and exploring the specific functions of MeHg-sulfhydryl conjugates on the central nervous system.
<p>A simple and sensitive method for the determination of free fatty acids (FFAs) using acridoné9́ethyĺṕtoluenesulfonate (AETS) as a fluorescence derivatization reagent by high performance liquid chromatography (HPLC) has been developed. Free fatty acid derivatives were separated on an Eclipse XDB́C<sub>8</sub> column with a good baseline resolution and detected with the fluorescence of which excitation and emission wavelengths of derivatives were set at <sub>ex</sub>=404 and <sub>em</sub>=440 nm, respectively. Identification of 19 fatty acid derivatives was carried out by online post́column mass spectrometry with an atmospheric pressure chemical ionization (APCI) source under positivéion detection mode. Nineteen FFAs from the extract of <i>Lomatogonium rotatum</i> are sensitively determined. The results indicate that the plant <i>Lomatogonium rotatum</i> is enriched with an abundance of FFAs and FFAs of higher contents, which mainly focus on even carbon atoms, C<sub>14</sub>, C<sub>16</sub>, and C<sub>18</sub>. The validation of the method including linearity, repeatability, and detection limits was examined. Most linear correlation coefficients for fatty acid derivatives are >0.9989, and detection limits (at signaĺtónoise of 3:1) are 12.3-43.7 fmol. The relative standard deviations (RSDs) of the peak areas and retention times for 19 FFAs standards are <2.24% and 0.45%, respectively. The established method is rapid and reproducible for the separation determination of FFAs from the extract of <i>Lomatogonium rotatum</i> with satisfactory results.</p>

The content ranges of gallic acid, hydroxysafflor yellow A, cinnamic aldehyde and piperine in Dangzuo samples of different Tibetan regions were 0.11341.69 mg x g(-1), 0.889-1.51 mg x g(-1), 0.000-40.606 mg x g(-1) and 1.96-2.73 mg x g(-1), respectively.; Conclusion: The method is a simple and effective for quality control of Tibetan medicine Dangzuo.;
This study established an HPLC fingerprint of Tibetan medicine Shaji Gao from different habitats and lay a foundation for Shaji Gao varieties identification and preparation process. The chromatographic condition was as follow: Agilent zorbax SB-C18 (4.6 mm x 250 mm, 5 μm) eluted with the mobile phases of acetonitrile and 0.4% phosphoric acid water in gradient mode. The flow rate was 1.0 mL x min(-1), and the detection wavelength was set at 360 nm. The fingerprints of 15 batches Shaji Gao were carried out by similarity comparation, 7 chromatographic peaks were extracted as the common peaks of fingerprint, 3 peaks were identified, which were quercetin, kaempferol and isorhamnetin. The similarity degrees of 14 batches of samples were above 0.9 and 1 batch of samples was below 0.9. This is the first established fingerprint of Shaji Gao by using HPLC. This method has good precision, stability and repeatability that it could provide basis for quality control and evaluation of Shaji Gao.
Obesity, a major health problem worldwide, is a complex multifactorial chronic disease that increases the risk for insulin resistance, type 2 diabetes, coronary heart disease, and hypertension. In this study, we assessed methods to isolate hypaphorine, a potent drug candidate for obesity and insulin resistance. Semi-preparative reversed-phase liquid chromatography (semi-preparative RPLC) was established as a method to separate three compounds, adenosine, l-tryptophan, and hypaphorine, from the crude extracts of <i>Caragana korshinskii </i>Kom. Due to its specific chemical structure, the effect of hypaphorine on differentiation and dexamethasone (DXM) induced insulin resistance of 3T3-L1 cells was investigated. The structures of the three compounds were confirmed by UV, ¹H-NMR, and <sup>13</sup>C-NMR analysis and compared with published data. The activity results indicated that hypaphorine prevented the differentiation of 3T3-L1 preadipocytes into adipocytes by down-regulating hormone-stimulated protein expression of peroxisome proliferator activated receptor <i>γ</i> (PPAR<i>γ</i>) and CCAAT/enhancer binding protein (C/EBP<i>α</i>), and their downstream targets, sterol regulatory element binding protein 1 c (SREBP1c) and fatty acid synthase (FAS). Hypaphorine also alleviated DXM-induced insulin resistance in differentiated 3T3-L1 adipocytes <i>via</i> increasing the phosphorylation level of Akt2, a key protein in the insulin signaling pathway. Taken together, we suggest that the method can be applied to large-scale extraction and large-quantity preparation of hypaphorine for treatment of obesity and insulin resistance.
<b>Abstract </b> Herbal medicinal materials have been used worldwide for centuries to maintain health and to treat disease. However, adulteration of herbal medicines remains a major concern of users and industry for reasons of safety and efficacy. Identification of herbal medicinal materials by DNA technology has been widely applied, started from the mid-1990s. In recent years, DNA barcoding of global plant species using four standard barcodes (<i>rbcL</i>, <i>matK</i>, <i>trnH</i>-<i>psbA</i> and ITS) has been a major focus in the fields of biodiversity and conservation. These DNA barcodes can also be used as reliable tools to facilitate the identification of herbal medicinal materials for the safe use of herbs, quality control, and forensic investigation. Many studies have applied these DNA barcodes for the identification of herbal medicinal species and their adulterants. The present article reviews efforts in the identification of herbal medicinal materials using the standard DNA barcodes and other DNA sequence-based markers.
Objective: To identify the common Tibetan herb Chuan-Bu.; Method: Local herbalists were visited to observe which plants were being used as Chuan-Bu. Samples of the indigenous plants were collected at the same time. Leaf materials were collected from field surveys. Total genomic DNA was extracted from silica gel-dried leaf samples. The PCR products were purified and directly sequenced.; Result: As the origin of Chuan-Bu in Tibet autonomous region was authenticated, two species were determined, i. e. Euphorbia stracheyiand E. wallichii. Also, based on our earlier research, the origin of Chuan-Bu in Gansu province, is from E. kansuensis. The sequences of ITS1 for E. stracheyi and E. wallichii were 261 bp in size, and 221 bp in ITS2, respectively. The size of the 5.8S coding region was 164 bp for all species examined in the genus. Especially, there was a heterozygous locus in ITS1 (C/G; position 72) for E. stracheyi. The nucleotide divergence between sequences of the 6 species in pairwise comparisons was calculated and the result showed that the variable site could be detected in each pairwise comparison of sequences. Also, there were 8 point mutations in the 5.8S coding region.; Conclusion: nrDNA ITS sequences can be used as the molecular markers to identify the Tibetan herb Chuan-Bu and such Traditional Chinese Medicines from the same genus Euphorbia as E. lathyris, E. humifusa and E. pekinensis.;
An HPLC-UV-MS method for simultaneous identification of predominant phenolics and minor nucleoside derivatives in<i> Gastrodia elata</i> was developed, which was based on their UV and MS characteristics summarized through a series of homemade reference standard experiments. Phenolics showed characteristic UV λ<sub>max</sub> at 267 nm, [M + NH₄]⁺ base peak in positive mode and [M-H]⁻ base peak in negative mode while nucleosides exhibited UV λ<sub>max</sub> at 255 nm, [M + H]⁺, [M-H + 2H₂O]⁻ or [M-H + CH₃COOH]⁻. Phenolics conjugates mainly underwent the consecutive loss of gastrodin residue (-268 U) and the combined loss of H₂O and CO<sub>2 </sub>from the citric acid unit under negative MS/MS conditions whereas nucleosides simply lost the ribose (-132 U) under positive MS/MS conditions. According to these characteristics, a special pattern under MS/MS conditions and reported compound data for<i> G. elata</i> in the literature, not only 15 phenolics were identified but also 6 nucleoside derivatives were identified. Among these compounds, seven phenolics and three nucleoside derivatives have not been reported yet from<i> G. elata</i>.
The ITS2 barcode was used toidentify Tibetan medicine "Dida", and tosecure its quality and safety in medication. A total of 13 species, 151 experimental samples for the study from the Tibetan Plateau, including Gentianaceae Swertia, Halenia, Gentianopsis, Comastoma, Lomatogonium ITS2 sequences were amplified, and purified PCR products were sequenced. Sequence assembly and consensus sequence generation were performed using the CodonCode Aligner V3.7.1. The Kimura 2-Parameter (K2P) distances were calculated using MEGA 6.0. The neighbor-joining (NJ) phylogenetic trees were constructed. There are 31 haplotypes among 231 bp after alignment of all ITS2 sequence haplotypes, and the average G±C content of 61.40%. The NJ tree strongly supported that every species clustered into their own clade and high identification success rate, except that Swertia bifolia and Swertia wolfangiana could not be distinguished from each other based on the sequence divergences. DNA barcoding could be used as a fast and accurate identification method to distinguish Tibetan medicine "Dida" to ensure its safe use.
Hippophae rhamnoides subsp. sinensis Rousi, Hippophae gyantsensis (Rousi) Y. S. Lian, Hippophae neurocarpa S. W. Liu & T. N. He and Hippophae tibetana Schlechtendal are typically used under one name “Shaji”, to treat cardiovascular diseases and lung disorders in Tibetan medicine (TM). A complete set of infrared (IR) macro-fingerprints of these four Hippophae species should be characterized and compared simply, accurately, and in detail for identification. In the present study, tri-step IR spectroscopy, which included Fourier transform IR (FT-IR) spectroscopy, second derivative IR (SD-IR) spectroscopy and two-dimensional correlation IR (2D-IR) spectroscopy, was employed to discriminate the four Hippophae species and their corresponding extracts using different solvents. The relevant spectra exhibited the holistic chemical compositions and variations. Flavonoids, fatty acids and sugars were found to be the main chemical components. Characteristic peak positions, intensities and shapes derived from FT-IR, SD-IR and 2D-IR spectra provided valuable information for sample discrimination. Principal component analysis (PCA) of spectral differences was performed to illustrate the objective identification. Results showed that the species and their extracts can be clearly distinguished. Thus, a quick, precise and effective tri-step IR spectroscopy combined with PCA can be applied to identify and discriminate medicinal materials and their extracts in TM research.

Lycium ruthenicum Murr. is commonly used in traditional Tibetan medicine, and the fruits of Lycium ruthenicum Murr. contain an immunologically active pectin which improves immune function against chronic diseases. The present study was performed to evaluate the immunomodulatory effects of Lycium ruthenicum Murr. polysaccharide 3 (LRGP3) in cyclophosphamide (Cy)-induced immunosuppressed mice. Mice were injected intraperitoneally once daily with low-dose (25 mg/kg), intermediate-dose (50 mg/kg), high-dose (100 mg/kg) of LRGP3 for 10 consecutive days, respectively. Compared with Cy group, LRGP3 accelerated recovery of spleen and thymus indices, enhanced T cell and B cell proliferation responses, as well as peritoneal macrophage phagocytosis. In addition, LRGP3 treatment restored the levels of interleukin-2 (IL-2), IL-6 and tumor necrosis factor-α (TNF-α) in the serum of Cy-treated mice. These results indicate that LRGP3 plays an important role in the protection against immunosuppression in Cy-treated mice and could be a potential immunomodulatory agent.
