The new steroidal glycosides from the aerial parts of Lepidogrammitis drymoglossoides
Journal of Asian Natural Products Research(2016)
摘要
Two new steroidal glycosides ponasteroside C (1) and ponasteroside D (2) were isolated from the aerial parts of Lepidogrammitis drymoglossoides. Their structures were elucidated by various spectroscopic techniques (IR, HRESIMS, 1D and 2D NMR). All compounds were evaluated for their cytotoxicity against HeLa and HCT-8 cell lines, and compounds 1 and 2 showed mild activity against all the test cell lines.
