Study on the chemical constituents of the South China Sea gorgonian Junceella juncea

Abstract

A new steroidal glycoside-4′-O-acetyl-3-O-[β-D-arabino- pyranosyl-oxy]-cholest-5-ene-3β,19-diol (1), and a new glycerol derivative-1,2-O-[2′-hydroxyoctadecyl]-glycerol (2), along with 16 known compounds were isolated from the EtOH/CH2Cl2 extracts of the South China Sea gorgonian coral Junceella juncea. The structures of 1 and 2 were established by extensive spectroscopic analysis, including 1D and 2D NMR data. © 2004 Pharmaceutical Society of Japan.
