摘 要 ：应用超声提取法提取文冠果种仁油，通过正交实验法考察了种仁粒径、提取时间、物料与溶剂比和超声功率4个因素对提取率的影响，得到了最佳提取工艺条件：粒径为0.5 mm，提取时间为90 min，物料与溶剂比为1：5(w/v)，超声功率为175 W，并用GC-MS分析了文冠果种仁油的脂肪酸组分，为进一步开发文冠果种仁油作为生物柴油的原料提供了科学依据。

Abstract:Ultrasonic extraction of oil from Xanthoceras sorbifolia kernel was studied with orthogonal method. The influencing factors, such as particle size, extraction time, ratio of material to solvent and ultrasonic power were researched in the experiment. The optimal conditions were obtained as follows: the particle size 0.5 mm, extraction time 90 min, ratio of material to solvent 1:5 (w/v) and ultrasonic power 175 W, the oil composition was analyzed by GC-MS. The present study provides a scientific reference for the potential raw material of biodiesel from Xanthoceras sorbifolia kernel oil.
