Fatty acids in polar lipids from etiolated Cichorium intybus.

Changes in the fatty acid (FA) content of polar lipids were studied during the postharvest period of Belgian endive (Cichorium intybus var. foliosum cv. Final). The major fatty acid present in these lipids was linoleic (33-62%) followed by palmitic (24-36%). Changes in the FA composition were observed after harvest in both leaves and flowering stalks. The most pronounced changes occurred in the younger leaves within the first 4 days postharvest. Older leaves showed the greatest amounts of total FA. Younger leaves had higher saturated to unsaturated FA ratios. Floral stalks and leaves showed a decrease in total FA and saturated to unsaturated FA ratios with time. The results are discussed in the relation to the diagnostic value in respect of plant tissue age determination.
