摘要:
A single specimen of the Antarctic nudibranch Austrodoris kerguelensis contained two major glyceride esters, 2'-acetoxyglyceryl (5R,10R,13R)-labda-8-en-15-oate (1) and 3'-acetoxyglyceryl (5R,10R,13R)-labda-8-en-15-oate (4), the diketones 6 and 7 that arise from oxidation of the 8,9-olefinic bond, and glyceryl (5R,10R,13R)-7-ketolabda-8-en-15-oate (8). The probable source of these metabolites is discussed.
