(Show)
Three new alkaloids, N-hexacosanoylanthranilic acid (1), N-octacosanoylanthranilic acid (2) and N-eicosanoyltyramine (3), along with 19 known compounds, were isolated from the seeds of Notopterygium incisum, whose rhizomes are used as a traditional Tibetan medicine. Their structures were elucidated by 1D, 2D NMR spectra and ESI-MS spectrometer evidence.
