A new diacylgalactolipid was isolated from the marine cyanobacterium Oscillatoria sp., and the structure was elucidated as (2 S )‐3‐ O ‐β‐ d ‐galactopyranosyl‐1‐ O ‐(9 Z ,12 Z ‐octadecadienoyl)‐2‐ O ‐(4 Z ‐hexadecenoyl)glycerol by enzymatic partial hydrolysis using lipase and physicochemical evidence, which included determining the double bond position in the hexadecenoic acid moiety.
