Abstract: To understand content and its constituents of waxgourd seed oil,univariate and orthogonal experiment and Weighing method and gas chromatography-mass spectrometry techniques was employed in the research. Through research obtained,the oil was well extracted at 80 ℃ for 2 h with 12 times (V/W) mixed solvent;and 14 kinds of fatty acids were contained.The oil rate is 16.0% by the extraction process.In the oil,unsaturated fatty acid contents are 88.6%;and linoleate is main component,and its content is 84.7%.The results are a reliable groundwork for reasonable exploitation of waxgourd seed oil.

Key words: waxgourd seed oil, extraction process, GC-MS, fatty acid
