新疆伽师酸梅核仁油中脂肪酸及不皂化物组成分析_白希 . Analysis of Fatty Acid and Unsaponifiable Matters in Jiashi Plum Kernel Oil from Xinjiang

Abstract

Basic components of Jiashi plum kernel was analyzed,and Jiashi plum kernel oil were extracted by Soxhlet extractor,after being methylated and saponified,the fatty acids composition and unsaponifiable matters were analyzed by gas chromatography-mass spectrometry(GC-MS).The results indicated that the content of crude protein and crude fat in the kernels of Jiashi plum kernel were 35.24% and 32.61%respectively.The total unsaturated fatty acids of the Jiashi plum kernel oil was 91.09% with oleic acid being the dominant fatty acid(up to 65.87%).Phytosterols were the main component of the unsaponifiable matters in Jiashi plum kernel oil,and the relative content of stigmast-7-en-3-ol,(3beta,5alpha) was up to 68.06%.So Jiashi plum kernel has the potential to be exploited as a valuable oil resource.
