采用超声波辅助提取黄秋葵籽油并采用 GC - MS 对其脂肪酸组成进行分析。通过单因素试验考察提取溶剂、原料粒度、料液比、提取温度、提取时间、超声功率对黄秋葵籽油得率的影响。在单因素试验基础上采用正交试验优化得到最佳提取工艺条件为：正己烷为提取溶剂，原料粒度40~60目，料液比1：9，提取温度50℃，提取时间75 min，超声功率80 W。在最佳条件下，黄秋葵籽油得率为26．26%。从黄秋葵籽油中鉴定出11种脂肪酸，主要为不饱和脂肪酸，含量最高的为亚油酸，占34．06%。%The ultrasonic - assisted extraction of Abelmoschus esculentus seed oil was studied and the fatty acid composition of Abelmoschus esculentus seed oil was analyzed by GC - MS. The effects of extraction solvent, material granularity, ratio of material to liquid, extraction temperature, extraction time and ul-trasonic power on the yield of Abelmoschus esculentus seed oil were studied by single factor experiment. Then the ultrasonic - assisted extraction conditions were optimized by orthogonal experiment as follows:with n - hexane as extraction solvent, material granularity 40 - 60 meshes, ratio of material to liquid 1: 9, extraction temperature 50 ℃, extraction time 75 min, ultrasonic power 80 W. Under the optimal conditions, the yield of Abelmoschus esculentus seed oil was 26. 26% ,and eleven kinds of fatty acids were identified from Abelmoschus esculentus seed oil, among which the content of linoleic acid was the highest, reaching 34. 06% .
