摘要：

1. 1. The major aglycones produced by acid hydrolysis of the saponins from the starfish Astropecten aurantiacus are identified as 3β,6α-dihydroxy-5α-pregn-9(11)-en-20-one (1), (17 E)- and (17 Z)-3β,6α-dihydroxy-5α-cholesta-9(11),17(20)-dien-23-one (9 and 10), (17 E)- and (17 Z)-3β,6α-dihydroxy-5α-cholesta-9(11), 17(20),24-trien-23-one (11 and 12), (20 E)-3β,6α-dihydroxy-5α-cholesta-9(11),20(22)-dien-23-one (4), and 17β-methyl-3β,6α-dihydroxy-18-nor-5α-cholesta-9(11),13-dien-23-one (13). 2. 2. A re-examination of the sapogenins from the starfish Marthasterias galcialis, in addition to the previously isolated 1, 3β,6α-dihydroxy-5α-cholesta-9(11)-en-23-one (2, dihydromarthasterone), 3β,6αdihydroxy-5α-cholesta-9(11),24-dien-23-one (3, marthasterone) and 3β,6α-dihydroxy-5α-chol-9(11)-en-23-one (14), has shown the presence of minor amounts of 9, 10, 4 and 13. 3. 3. A [13C]NMR study of the major sapogenins, 9 and 10, from A. aurantiacus, and 1, 2 and 14 from M. glacialis is also reported. © 1979.
