摘要

One kinds of glycolipid (SBI) have been isolated from the marine brown alga Sargassum hemiphyllum (Turn.) Ag. The structures of SBI have been determined as the sodium salt of 1-0-acyl-3-0-(6′-sulfo-c-D-quinovopyrannosyl) glycerol (acyl: tetradecanoyl, pentadecanoyl, 11-hexadecenoyl, hexadecanoyl, 10,13-octadecadienoyl, 9-octade cenoyl, 15-metylheptadecanoyl and 11-eicosenoyl 17:1.5:19:153:1: 19:1:2) on the basis of chemical and spectral evidence and GC-MS analysis, respectively. Four constituents of the SBI were new compounds [the sodium salt of 1-0-(ll″-hexadecenoyl)-3-0-(6′-sulfo-α-D-quinovopyrannosyl) glycerol, the sodium salt of 1-0-(10",13"-octadecadienoyl)-3-0-(6′-sulfo-α-D-quinovopyrannosyl) glycerol,and the sodium salt of 1-0-(15"-metylhexadecenoyl)-3-0-(6′-sulfo-c-D-quinovopyrannosyl)glycerol, and the sodium salt of 1-0-(ll"-eicosenoyl)-3-0-(6′-sulfo-α-D-quinovopyrannosyl)glycerol]. All compounds were isolated from marine brown alga for the first time.
