Abstract
Seasonal changes in lipid composition in the flavedo tissues of Naruto fruit were determined during August to early June.Total fatty acid content of phospho- and glycolipids, particularly that of glycolipids, decreased considerably with increased aging of the rind except during midwinter. In mid-winter that of neutral, phospho- and glycolipids showed a sharp peak, due largely to an increase in linoleic (18:2) acid in the first two and linolenic (18:3) acid in the last.Content of major phospholipids, phosphatidylcholine (PC) and phosphatidylethanolamine (PE); and content of major glycolipids, mono-(MGDG) and di-galactosyl-diglyceride (DGDG), behaved in a way similar to that of phospho- and glycolipid total fatty acids, respectively. Seasonal variations in DGDG content were paralleled by, but greater than MGDG content. The PC/PE ratio decreased steadily from August to December and thereafter remained unchanged. Free sterol content decreased from August to October and thereafter changed little except for showing a peak in mid-winter. However, the sterol/phospholipid ratio was relatively constant during winter. The sitosterol/stigmasterol ratio more than doubled in the maturing period (December-June) compared with that in the growing period (August October).
