摘要
为了明确冬瓜子油的含量与组成,本研究采用单因素实验与正交实验综合评定相结合的方法,以称重法和气相色谱-质谱联用(GC-MS)技术,对冬瓜子中油脂的提取及其组成进行了研究。结果显示冬瓜子油的最佳提取工艺为:使用12倍(V/W)量的复合溶剂,于80℃,提取2 h,提取率可达16.0%;GC-MS分析显示冬瓜子油含有14种脂肪酸,亚油酸为主要成分,含量为84.7%,不饱和脂肪酸总含量为88.6%。多种不饱和脂肪酸的存在,为冬瓜子油的开发利用奠定了物质基础。
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 re- search 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 ex- ploitation of waxgourd seed oil.
