Effects of Cultivars and Geography in China on the Lipid Characteristics of Camellia oleifera Seeds.
J Oleo Sci. 2019 Nov 07; 68(11):1051-1061.JO

Abstract

New cultivars of Camellia oleifera have been developed and planted in southern China. However, lipid characteristics of their seed oils were still unclear. In this study, nine C. oleifera fruits were collected from different cultivars in different planting regions, and the lipid characteristics, such as oil content, fatty acid composition, triacylglycerol composition, tocopherol content and sterol composition were investigated for their seed oils. The oil content in Yuekexia-2 was the lowest (11.6%), while those in other cultivars ranged from 22.3% to 29.6%. The major fatty acids of C. oleifera seed oils (COSOs) were palmitic acid (16:0, 8.4-11.5%), oleic acid (18:1, 76.3-80.5%), and linoleic acid (18:2, 7.9-12.2%), respectively. Trioleoylglycerol (OOO) was the most abundant triacylglycerol specie (more than 50%) in the COSOs. COSOs contained 21.2-36.4 mg/100 g of α-tocopherol. Seven sterols and squalene were found in all COSOs, while the COSOs showed significant differences in their contents of unsaponifiable matters. The planting region and the cultivar type significantly affected some of the lipid characteristics with the C. oleifera seeds.
