In five acidic glycerophospholipids (phosphatidylglycerol, phosphatidylinositol, cardiolipin and two N-acyl phospholipids containing ethanolamine) from grains of japonica and indica rices, phosphatidylglycerol had commonly the lowest unsaturation index and cardiolipin had the highest. The order of unasaturation index in each lipid did not depend on the variety of rice. It was assumed that unsaturation index of the lipids changed with temperature during grain ripening except for cardiolipin. Cardiolipin usually had a high level of linoleic acid and a low level of palmitic acid compared with other lipids.
