Abstract

Comparing different extraction agents which were used to extract the seed oil of Chinese Dwarf cherry, the petroleum ether is the best. To study the impact of the extraction temperature, extraction time and solid-liquid ratio these three factors on kernel oil extraction, the best extraction parameters was found out: 60 ℃, 6 h, and the solid-liquid ratio is 1 : 10. Under the best extraction process, the oil extraction rate is 97.62%. Gas chromatography was also used to determined the fatty acid composition. Five main fatty acids including palmitic acid, palmitic acid, stearic acid, oleic acid and linoleic acid were detected, of which are mainly oleic acid (68.53%) and linoleic acid (27.43%).
