摘要
以樟树籽为研究对象,对其仁油及壳油的油脂组成进行分析比较。结果表明,仁油中富含癸酸和月桂酸,占95%左右,并且均匀分布在甘油三酯Sn-1,2和3位上;壳油中脂肪酸主要为癸酸、月桂酸和油酸,其中癸酸和月桂酸总量为48%左右,半数分布在Sn-2位上,油酸含量达27.60%,并集中在Sn-1,3位上。仁油中豆甾醇含量为33.89mg/100g,壳油中豆甾醇含量是仁油的3倍左右。仁油中不含角鲨烯或者其含量低于HPLC检出限,壳油中角鲨烯含量为1.88mg/100g。樟树籽仁油中主要含有α-VE,δ-VE和γ-VE,总量为30.45mg/100g,其中以γ-VE含量最高,为19.47mg/100g;壳油中VE总量是仁油的2～3倍,其中以α-VE含量最高。
The grease composition of Cinnamomum camphora seed kernel oil and shell oil was analyzed and compared.The results indicated that the kernel oil was rich in capric acid and lauric acid accounting for about 95%,and evenly distributed at Sn-1,2 and 3 positions of triacylglycerols.The major fatty acids of the shell oil were capric acid,oleic acid and lauric acid.The total content of capric acid and lauric acid was about 48%,half of which was distributed at Sn-2 position.The content of oleic acid was 27.60% and concentrated at Sn-1 and Sn-3 positions.The stigmasterol content of the kernel oil was 33.89 mg/100 g,which was three times of that in the shell oil.The kernel oil contained without squalene,or with content lower than the HPLC detection limit.The squalene content of the shell oil was 1.88 mg/100 g.Cinnamomum camphora seed kernel oil mainly contained α-VE,δ-VE and γ-VE with 30.45 mg/100 g totally,among which the γ-VE content was highest with about 19.47 mg/100 g.The total VE content of the shell oil was two or three times than that of the kernel oil,with highest content of α-VE.
