沙枣种子油的超声波辅助提取及理化性质分析 GC-MS . Ultrasound-Assisted Extraction of Elaeagnus Angustifolia Seeds Oil and Its Physical-Chemical Properties

Abstract

In this paper,the effect of ultrasonic power,extracting temperature,extracting time,and ratio of material to liquid was studied.The result by an orthogonal experiment indicated that effectiveness factors on oil yield was the order as follows: extracting temperature extracting time ultrasonic power ratio of material to liquid.The optimum factors were: ultrasonic power 120 W,extracting temperature 30 ℃,extracting time 30 min and the ratio of material to liquid 1∶ 6 g / mL.The extraction rate of Elaeagnus angustifolia L.seeds oil was 26.07%.The results of GC-MS analysis showed that the main components of fatty acids were: 9,12-octadecadienoic acid 49.12%,9 octadecenoic acid 37.26%,hexadecanoic acid 3.91% and octadecanoic acid 1.63%,etc.
