1. Monogalactosyl diglyceride (MGD), digalactosyl diglyceride (DGD), trigalactosyl diglyceride (TGD) and sulfoquinovosyl diglyceride (SQD) were found to be present in pumpkin. MGD, DGD and TGD were isolated and purified.
2. Main fatty acids of glyceroglycolipids isolated were linoleic and linolenic acid, and major sugar component was galactose.
3. Fundamental structure of TGD in pumpkin was presumed to be 1, 2-diacyl-3-O-[α-D-galactopyranosyl-(1'→6')-O-α-D-galactopyranosyl-(1'→6')-O-β-D-galactopyranosyl]-sn-glycerol.
