title: A new diacylgalactolipid containing 4Z-16:1 from the marine cyanobacterium Oscillatoria sp.
abstract: A new diacylgalactolipid was isolated from the marine cyanobacterium Oscillatoria sp., and the structure was elucidated as (2S)-3-O-beta-D-galactopyranosyl-1-O-(9Z,12Z-oc-tadecadienoyl)-2-O-(4Z-hexadecenoyl)glycerol by enzymatic partial hydrolysis using lipase and physicochemical evidence, which included determining the double bond position in the hexadecenoic acid moiety.
