山茱萸籽油的理化性质及脂肪酸组成分析

主要对山茱萸籽的组成、山茱萸籽油的理化性质及脂肪酸组成进行了分析.结果表明:山茱萸籽中还原糖、总糖、粗蛋白和粗脂肪含量分别为29.2％、64.7％、21.7％和13.1％.山茱萸籽油酸值(KOH)、碘值(Ⅰ)、过氧化值及皂化值(KOH)分别为0.97 mg/g、113.8 g/100 g、8.9 mmol/kg、186.5 mg/g.山茱萸籽油中饱和脂肪酸以棕榈酸(10.40％)为主,其次是硬脂酸(3.49％)和山嵛酸(3.32％)；不饱和脂肪酸中油酸(35.80％)和亚油酸(34.60％)含量较高,还含有5.51％的芥酸.

Physicochemical properties and fatty acid composition of Cornus officinalisseed oil

The composition of Cornus officinalis seeds,the physicochemical properties and the fatty acid composition of the Cornus officinalis seed oil were mainly analyzed.The content of the reducing sugar,total sugar,crude protein and crude fat of the Cornus officinalis seed were 29.2%,64.7%,21.7% and 13.1%,respectively.The acid value,iodine value,peroxide value and saponification value of Cornus officinalis seed oil were 0.97 mgKOH/g,113.8 gI/100 g,8.9 mmol/kg and 186.5 mgKOH/g,respectively.The saturated fatty acids of Cornus officinalis seed oil were mainly palmitic acid(10.40%),stearic acid(3.49%)and behenic acid(3.32%),and the unsaturated fatty acids were mainly composed of oleic acid(35.80%)and linoleic acid(34.60%).Moreover,it was found that there was 5.51% of the erucic acid in Cornus officinalis seed oil.
