Abstract:

The seed oil of Discocleidion rufescens in euphorbiaceae collected from 4 sampling suburb sites of Jishou city was extracted by ultrasonic wave-assisted extraction, and the fatty acid constituents were analyzed by gas chromatography-mass spectrometry (GC-MS). The results showed that the average extraction percentage of seed oil was 22.71%, and the fatty acid components were of 8, 7, 5 and 4 kinds, respectively. The components of high content from 4 sampling points included linolenic acid (52.38%), linoleic acid (28.18%), stearic acid (13.30%) and palmitic acid (5.78%), with the sum of which took 99.47% of the total fatty acid.

Key words: Discocleidion rufescens, seed oil, fatty acid component
