Abstract

Two new steroidal saponins (1 and 2) were isolated from the dried bulbs of Allium macrostemon Bunge. Their structures were elucidated by the spectral data as 26-O-β-D-glucopyranosyl-5α-furost-25 (27)-ene-3β, 12β, 22, 26-tetraol-3-O-β-D-glucopyranosyl (1→2) [β-D-glucopyranosyl (1→3)]-β-D-glucopyranosyl (1→4)-β-D-galactopyranoside (1) and 26-O-β-D-glucopyranosyl-5β-furost-20 (22)-25 (27)-dien-3β, 12β, 26-triol-3-O-β-D-glucopyranosyl (1→2)-β-D-galactopyranoside (2), respectively. Their cytotoxic activities on several cancer cell lines (MCF-7, NCI-H460, SF-268 and HepG2) were tested. 1 showed special cytotoxity on SF-268, while 2 showed cytotoxity on NCI-H460 and SF-268 cell lines, respectively.
