Camparison of Fatty Acid between Camellia reticulate f. simpex Seed and Camellia oleifera Seed in Yunnan

The oil content of Camellia reticulate f.simpex seed and Camellia oleifera seed were determined by extraction with ultrasonic method.And the fatty acid compositions of their oil were analyzed by the GC/MS method,after esterification with methanol at NaOH,respectively.The results show as follows:(1)The oil content of Camellia reticulate f.simpex seed is higher than Camellia oleifera seed,and the ratio of content up to 38.3% and 36.0%s respectively;(2)The constitutes of fatty acid oil from Camellia oleifera seed and Camellia reticulate f.simpex seed are comparability,but there are some differences in ratio.The unsaturated acids and saturated acids are up to 83.5% and 16.5%,among the palmitic and stearic acid being 16.4%,and the oleic and linoleic acid being 83.0% in Camellia reticulate f.simpex oil.The unsaturated acids and saturated acids are up to 89.7% and 10.2%,among the palmitic and stearic acid being 10.1%,and the oleic and linoleic acid being 89.1% in Camellia oleifera oil;(3)The palmitic and stearic acid in Camellia reticulate f.simpex oil are higher,and the oleic acid is lower,and the linoleic acid is similar,than in Camellia oleifera oil.
