摘要

Abstract

Six steroids have been isolated from ethanolic extract of green alga Chaetomorpha basiretorsa Setchell 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 (IC50>10 μg /ml) against KB

Bel-7402

PC-3M

Ketr 3 and MCF-7 cell lines.
