[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. 展开更多

In this study, the ethanol extract of pomegranate seed was prepared and its antioxidant activities were investigated. It was found the total phenolic content in the extract was as high as 41.791 mg GAE/g. And the extract showed high antioxidant activity measured as scavenging of DPPH radicals, hydroxyl radicals. It also exhibited strong antioxidant activity in reducing power and Rancimat test. These results demonstrated Pomegranate seeds could serve as a new source of natural antioxidant. 展开更多
