摘要：

The heterocyst glycolipids of the cyanobacterium Cyanospira rippkae have been isolated and their structures established to be 1-()-alpha-D-glucopyranosyl)-3R,27R-octacosanediol and 1-(O-alpha-D-glucopyranosyl)-27-keto-3R-octacosanol by spectroscopic and chemical means. The absolute configuration at the two stereogenic centres in the aglycone moiety of the former compound has been established in a single step by Mosher's method on the triol derivative. The akinetes of C. rippkae contain the same glycolipids.
