GC-MS Analysis of Seeds from Different Pomegranate Varieties

摘要

[Objectives]This study aimed to study and analyze the main components of the oil from seeds of 8 different pomegranate varieties.[Methods]The oil in sour and sweet pomegranate seeds was extracted by ultrasonic-assisted method,and the composition of the soil after methyl esterification was identified by GC-MS.[Results]The oil yield of the four sweet pomegranate varieties and the four sour pomegranate varieties ranged from 9.43%-16.97%.A total of 6 compounds were identified in the methyl esterified pomegranate seed oil by GC-MS.[Conclusions]There were no significant differences in oil yield between sweet and sour pomegranate varieties(P>0.05).The content of methyl punicate in the four sweet pomegranate varieties was 52.18%-78.06%,and that in the four sour pomegranate varieties was 78.25%-84.55%.The content of methyl punicate in sour pomegranate was slightly higher than that in sweet pomegranate.
