[目的]研究不同物种及品种油茶籽营养物质变化,建立基于理化及营养特性的综合评价技术。[方法]测定11个油茶物种和20个普通油茶品种油茶籽含油率、脂肪酸、酸值、过氧化值、α-生育酚、角鲨烯、β-谷甾醇和酚类物质等理化和营养指标,应用主成分分析法进行综合评价。[结果]不同物种及品种油茶籽酸值和过氧化值均较低,α-生育酚、角鲨烯、β-谷甾醇和总酚含量均存在显著性差异,所含脂肪酸主要有油酸、亚油酸、棕榈酸和硬脂酸,酚类物质主要为没食子酸、表儿茶素、邻香草醛、邻香豆酸和反式肉桂酸。[结论]不同物种及品种油茶籽含油率、微量营养物质(α-生育酚、角鲨烯、β-谷甾醇和总酚)组成存在显著...

[Objective] To establish a comprehensive evaluation technology base on the changes of seed nutriments of different oil camellia species and varieties. [Method] The oil content, fatty acid compound, acid value, peroxide value, α-tocopherol, squalene, β-sitosterol and phenols in the seeds of 11 oil camellia species and 20 oil camellia varieties were determined and analyzed by principal component analysis to comprehensive evaluation. [Result] The acid value and peroxide value were low, the contents of α-tocopherol, squalene, β-sitosterol and p...
