Steroids from green alga Chaetomorpha basiretorsa Setchell
摘要
Abstract
Six steroids have been isolated from ethanolic extract of green alga Chaetomorpha basiretorsa Setehell by a combination of repeated normal phase silica gel and Sephadex LH-20 gel column chromatography as well as recrystallization. Using spectroscopic methods including MS and NMR, their structures were determined as β-lawsaritol (1), saringosterol (2), 24-hydroperoxy-24-vinyl-cholesterol (3), β-stigmasterol (4), stigmast-4-en-3α, 6β-diol (5), 29-hydroxystigmasta-5, 24 (28)-dien-3β-ol (6). All these compounds were obtained from this genus for the first time and they were inactive (IC5010 μg/ml) against KB, Bel-7402, PC-3M, Ketr 3 and MCF-7 cell lines.关键词
