摘要
本研究旨在优化索氏法提取琉璃苣籽油的工艺,以琉璃苣籽油提取率为指标,利用单因素试验和响应面法研究索氏法提取工艺中提取时间、提取剂体积和提取温度对提取率的影响,同时利用气相色谱仪对琉璃苣籽油中的脂肪酸进行分析鉴定。结果显示,粉碎的琉璃苣种子10 g,工艺条件为提取时间4.16 h,提取溶剂体积108.81 ml,提取温度83.15℃时,琉璃苣籽油提取率最高(34.05%)。提取的琉璃苣籽油中共鉴定出15种脂肪酸,包括9种不饱和脂肪酸,其中亚油酸占37.75%,γ-亚麻酸占20.96%,油酸占9.20%。本试验的提取方法简单易操作,可为琉璃苣的产业化开发和利用提供依据。
To optimize the Soxhlet extraction technology for borage seed oil,the influences of extraction time,extraction solvent volume and extraction temperature on the extraction rate of the borage seed oil were studied by single factor test and response surface method.The fatty acids in borage seed oil were determined by gas chromatography.The results showed that borage seed oil extraction rate reached the highest level (34.05%) under the conditions of extraction time 4.16 h,the volume of extraction solvent 108.81 ml and extraction temperature at 83.15 ℃.Totally 15 kinds of fatty acids were identified in borage seed oil,including nine kinds of unsaturated fatty acids,among which,linoleic acid accounted for37.75%,gamma linolenic acid accounted for 20.96%,and oleic acid accounted for 9.20%.
