A new asterosaponin named novaeguinoside A, along with a known saponin, asteronyl pentaglycoside sulfate, was isolated from the starfish Culcita novaeguineae. The new compound was identified to be sodium 6α-O-{β-D-fucopyranosyl-(1→2)-β-D-fucopyranosyl-(1→4)-[β-D- quinovopyranosyl-(1→2)]-β-D-xylopyranosyl-(1→3)-β-D-quinovopyranosyl}-5α-pregn-9(11)-en- 20-one-3β-yl-sulfate by extensive spectral analysis and chemical evidence. 展开更多

Two new 24-hydroxylated asterosaponins, sodium (20R,24S)-6α-O-(4-O-sodiumsulfato-β-D-quinovopyranosyl)-5α-cholest- 9(11)-en-3β,24-diol 3-sulfate (1) and sodium (20R,24S)-6α-O-β-O-methyl-β-D-quinovopyr... Two new 24-hydroxylated asterosaponins, sodium (20R,24S)-6α-O-(4-O-sodiumsulfato-β-D-quinovopyranosyl)-5α-cholest- 9(11)-en-3β,24-diol 3-sulfate (1) and sodium (20R,24S)-6α-O-β-O-methyl-β-D-quinovopyranosyl-(1→2)-β-D-xylopyranosyl- (1 → 3)-[3-D-glucopyranosyl]-5α-cholest-9(11)-en-3β,24-diol 3-sulfate (2), were isolated from the starfish Culcita novaeguineae. Their structures were elucidated by extensive spectral analysis and chemical evidences. 展开更多
