摘要
Three polyhydroxylated steroids were isolated from the Far-Eastern starfish Hippasteria phrygiana collected from the Sea of Okhotsk and were characterized as a new glycoside phrygioside A, viz., sodium (20R, 24S)-3 beta,4 beta,7 alpha,8,15 beta,24-hexahydroxy-24-O-[3-O-methyl-beta-D-xylopyranosyl-(1 -> 2)-alpha-L-arabinofuranosyl]-5 alpha-cholestan-6 alpha-yl sulfate, its aglycone, and the already known marthasterone sulfate.
