Trace Component Characteristic of Petroleum Ether Extracts from Different Camellia Seed Oil Products

Camellia oleifera b is an evergreen tree that are widely planted in the subtropical region of southern China. The oil from C. oleifera seed is high-grade edible oil that is unique to China, with rich unsaturated fatty acids. C. oleifera can be obtained through a series of processing technology, such as hair oil, refined oil and so on. However, the trace active components vary in Camellia seed oil products at different processing stages, therefore, the trace components characteristic of petroleum ether extracts from 5 Camellia seed oil products (crude oil, first-grade finished oil, second-grade finished oil, refined oil, cold-pressed oil) were analyzed. The petroleum ether extract of first-grade finished oil is rich in Elaidic acid, while the contents in other 4 Camellia seed oil products are different distinctly, which ban be used to reduce cholesterol content and as food additive. The petroleum ether extracts from all 5 Camellia seed oil products have cis-11-octadecenoic acid, cis-9-Octadecenoic acid, octadec-9-enoic acid, and some components which can be developed into materials for cosmetics and biomedicine.
