Abstract: (Show)
Plant-based natural products represent an alternative to chemical compounds for the control of mites in veterinary medicine. Here, the essential oil of Elsholtzia densa (E. densa) Benth was extracted using hydrodistillation at a rate of 1.2%. The chemical composition of the essential oil was determined by gas chromatographymass spectrometry (GC-MS) analysis. The GC-MS analysis indicated that the principal compounds in the volatile oil of the sample were 4-Pyridinol (28.16%) and thymol (26.58%). The acaricidal activity of E. densa oil against Sarcoptes scabiei (S. scabiei) was tested in vitro. Toxicity test data were analysed using a complementary log-log (CLL) model. The E. densa oil was prepared in five concentrations by dilution with liquid paraffin (1, 2, 4, 8 and 16 mg/ml) and exhibited strong toxicity against S. scabiei with LT50 values of 16.637, 5.075, 2.884, 1.184 and 0.760 h, respectively. The LC50 values were 7.678, 4.623, 2.543, 1.502, 1.298 and 0.981 mg/ml for S. scabiei at 1, 2, 4, 8, 16 and 24 h, respectively. Compared to the control, the essential oil showed significant effects against S. scabiei in vitro. At 16 mg/ml, E. densa oil was found to kill all mites within a 16-h period. The results indicate that E. densa oil possesses potential acaricidal activity in vitro and may be exploited as a novel drug for the effective control of S. scabiei. [ABSTRACT FROM AUTHOR]
