中文摘要：

研究以正己烷为溶剂超声辅助提取山茱萸籽油的工艺,并对其成分进行分析。采用响应曲面优化法（RSM）优化山茱萸籽油的提取工艺,确定最佳提取工艺参数为提取温度40℃、提取时间40min、液料比10：1（mL/g）,在此条件下,山茱萸籽油的一次提取率为97.08%（出油率7.90%）。利用GC-MS对山茱萸籽油中脂肪酸成分进行分析,结果表明：山茱萸籽油的主要脂肪酸成分为油酸（61.89%）、硬脂酸（19.99%）、棕榈酸（7.63%）和亚油酸（6.33%）等,不饱和脂肪酸占脂肪酸总量的69.45%;采用高效液相色谱法测定,山茱萸籽油中VE含量为76.0mg/100g。

Abstract： Response surface methdology was employed to optimize the ultrasound-assisted extraction of Comus officinalis seed oil. Meanwhile, its chemical composition was analyzed by GC-MS. The optimal extraction conditions were determined as 40 ℃ of extracion temperatrure, 40 rain of extraction time, and 10：1 of liquid-to-solid raio （mL/g）. Under these conditions, the extraction yield of Comus officinalis seed oil based on the dry weight of Comus officinalis kernels was 7.90%, accounting for 97.08% of that obtained from Soxhlet extraction. The predominant fatty acids in Comus officinalis seed oil were oleic acid （61.89%）, stearic acid （19.99%）, palmitic acid （7.63%）, linoleic acids （6.33%）, and so on. The percentage of unsaturated fatty acids relative to total fatty acids was 69.45%. In addition, the vitamin E content in Comus officinalis seed oil, as determined by HPLC, was 76.0 mg/100 g.
