Content and Fatty Acid Composition of Sulfoquinovosyldiacylglycerol in Conifer Leaves Grown in Hokkaido, Japan

Abstract

Sulfoquinovosyldiacylglycerol (SQDG) contents in conifer leaves and their fatty acid (FA) compositions were determined. The SQDG content was 16–36 mg/100 g, and was high in Picea glehnii. Palmitic and α-linolenic acid were the usually predominant FAs. In Picea, the proportion of α-linolenic acid was low, and those of oleic and linoleic acid were high. The essential oil residues of Abies sachalinensis leaves were found to be a potential source of SQDG material.
