Characterization of phospholipids from glyphosate-tolerant soybeans

The phospholipids from three control and two glyphosate-tolerant soybean cu ltivars were isolated by extraction of soy flakes with hexane and character ized after separation by high-pressure liquid chromatography. In addition, several lots of commercial fluid lecithin were analyzed and the results wer e compared to values published in the literature. Phosphatidylcholine, phos phatidylethanolamine, phosphatidylinositol, and phosphatidic acid were iden tified as major components in these cultivars and in the commercial lecithi n samples. The results showed that glyphosate-tolerant soybeans yield lecit hin comparable and equivalent to conventional soybean cultivars.
