Determination of Fatty Acid Composition and Vitamin E Content of Camellia Oleifera Oil by Chromatographic Technique

Abstract:

In this manuscript,fatty acid composition and Vitamin E content of Camellia oleifera oil were analyzed by Gas Chromatograph and HPLC respectively.The results show that: the primary crushing oil and refining oil are both contain 4 kinds of fatty acids mainly,which are palmic acid(7.68% and 8.92%),stearic acid(1.66% and 1.78%),oleic acid(82.90% and 81.90%),linoleic acid(7.17% and 7.22%);the linear range of VE was 0.5~2.5 μg(R2=0.999 3),and the mean recovery was 98.05%,RSD=0.75%(n=5).The VE content of primary crushing oil was 207mg/kg,which declined to 107.07mg/kg in refining oil.The chromatographic methods established in this text are fast,convenient and reliable.
