Camellia seed oil is widely used in the food, health, cosmetics and medicine industries in China. The present study aimed to investigate fatty acids, triacylglycerols (TGAs) and sn-2 fatty acids distributions variations in seed oil from 46 kinds of Camellia cultivars. The predominant fatty acids was oleic acid (18:1ω9) with 71.30% (average). The sn-2 position was mainly occupied by oleic acid, linoleic acid and palmitic acid. Fifteen TAGs species were found and the main TAGs were OOO + SLO, OOP and OOL+SLL. The trisaturated TAGs species were n...
