Abstract:
Two previously undescribed steroidal compounds, 16, 23-epoxy-22, 26-epimino-cholest-22(
N), 23, 25(26)-trien-3
β-ol-3-
O-
β-D-glucopyranosyl-(1→2)-
β-D-glucopyranosyl-(1→4)-
β-D-galactopyranoside (
1 ) and 26-
O-
β-D-glucopyranosyl-(25
R)-5
α-furost-20(22)-en-3
β, 26-diol (
2 ), together with 7 known ones including 26-
O-
β-D-glucopyranosyl-(25
R)-5, 20(22)-dien-furost-3
β, 26-diol (
3 ), (25
R)-5-en-spirost-3
β-ol-
O-
β-D-glucopyranosyl-(1→4)-
α-L-rhmanopyranosyl-(1→2)-
β-D-galactopyranoside (
4 ), funkioside D (
5 ), aspidistrin (
6 ), tigogenin-3-
O-
β-D-lucotrioside (
7 ), desglucolanatigonin Ⅱ (
8 ), and degalactotigonin (
9 ), were isolated from
Solanum lyratum Thunb. Their cytotoxic activities were tested in two cancer cell lines by MTT method. One of the steroidal glycosides (
6 ) showed significant cytotoxic activity against gastric cancer SGC7901 and liver cancer BEL-7402 cells.
