摘要: A new steroidal sapogenin named 25-R-spirosta-3,5-dien-12β-ol(1) was isolated from the dried roots of Chlorophytum laxum R. Br. along with five known compounds, namely, diosgenin(2), stigmasterol(3), β-sitosterols(4), estigmasterol-3-O-β-D-glicopyranoside(5) and 3-O-β-authemisol(6). The structure of compound 1 was elucidated by the analysis of IR, HRESI-MS, 1D and 2D NMR spectral data. Compounds 2-5 were isolated from Chlorophytum laxum R. Br. In addition, all the compounds were evaluated for cytotoxicity on the human nasopharyngeal carcinoma cancer cell line 5-8F. Among them, the newly identified 25-R-spirosta-3,5-dien-12β-ol(1) and diosgenin(2) exhibited high cytotoxicity on 5-8F cells, with IC50 values of 24.8 and 41.9 μmol/L, respectively.
