✦ Synopsis

in seed triglycerides has been well characterized using pancreatic lipasel-4). Palmitic, stearic, eicosenoic, and erucic acids are esterified primarily at the 1,3positions; while oleic, linoleic, and linolenic acids occuppy all three positions. The seed triglycerides of numerous monocotyledon and dicotyledon species also contain medium chain length fatty acids such as 10:0, 12:0, and 14:0. Litchfield 5) has reported on the positioning of such acids in Palmae (monocotyledon) seed triglycerides, but only three isolated lipolysis results are available for dicotyledon species 4, 6, 7). The present study was undertaken to characterize the positional distribution of 10:0, 12:0, and 14:0 in various dicotyledon seed triglycerides by hydrolysis with pancreatic lipase. Regular positional distribution patterns correlating with traditional taxonomic groupings have been found.
