Glycerol derivatives and sterols from Sargassum parvivesiculosum

Chem Pharm Bull (Tokyo). 2004 Aug;52(8):986-8. doi: 10.1248/cpb.52.986.

Abstract

Five glycerol derivatives (1-5) and three sterols (6-8) were isolated from the EtOH extraction of the brown alga of Sargassum parvivesiculosum. On the basis of spectroscopic methods, their structures were elucidated as 1,3-di-O-[2',2'-di-(p-phenylene) isopropylidene] glycerol (1), (2S)-1-O-heptatriacontanoyl glycerol (2), (2S)-1,2-di-O-palmitoyl-3-O-(6-sulpho-alpha-D-quinovopyranosyl) glycerol (3), (2S)-1-O-palmitoyl glycerol (4), (2S)-1,3-di-(O-palmitoyl)-2-O-octadecanoyl glycerol (5), 24-ethylcholest-5,23Z-dien-3beta,28zeta-diol (6), 24-vinylcholest-5-en-24zeta-hydroperoxy (7), 24-ethylcholest-4,24(28)-dien-3beta-ol (8), respectively. Among them, 1 and 2 were new.
