Two new 24-hydroxylated asterosaponins, sodium (20R,24S)-6α-O-(4-O-sodiumsulfato-β-D-quinovopyranosyl)-5a-cholest9(11)-en-3b,24-diol 3-sulfate (1) and sodium (20R,24S)-6α-O-[3-O-methyl-b-D-quinovopyranosyl-(1→2)-β-D-xylopyranosyl(1→3)-β-D-glucopyranosyl]-5a-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.
