木兰科四种植物种子油的提取及脂肪酸成分分析 . Extraction of seed oil and fatty acid analysisfrom four species in Magnoliaceae

Abstract

The seed oil from Magnolia denudata,M.officinalis sbusp.biloba,Michelia maudiae and M.macclurei in Magnoliaceae were extracted by ultrasonic assisted extraction technology and microwave assisted extraction technology. The compositions of the oil were analyzed by gas chromatography mass spectrometry after methyl esterification. The results revealed that the oil extraction rate were different in four species,the average contents were 27.35% in Magnolia denudata,23.34% in M.officinalis sbusp.biloba,31.66% in Michelia maudiae and 9.27% in M.macclurei. Different extraction methods resulted in different components and relative contents of fatty acid,but the main and common components of above four seed oils were similar,including oleic acid,linoleic acid,stearic acid and palmitic acid.
