摘      要：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.
