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.
