摘要
采用国标方法对山苍子[Litsea cubeba(Lour.)Pers.]果和山苍子叶中挥发油、矿物质元素、氨基酸等营养成分总量及组分进行了测定,旨在为山苍子资源开发利用提供依据。结果表明,山苍子果中的脂肪、粗纤维含量明显高于叶中;山苍子叶的蛋白质、碳水化合物、维生素C含量明显高于果中。山苍子油主要存在于山苍子果中。山苍子果中磷、锌、铜、钾含量较高,山苍子叶中铁、锰、硒、钙、镁含量较高。山苍子果和叶中氨基酸组成相似,果中的必需氨基酸数值低于叶中。综合来看,山苍子果和叶中均含有精油,都可用于精油的提取,同时二者营养价值丰富,有被开发为食物的潜力。
The total amount and components of volatile oil,mineral elements and amino acids in fruit and leaves of Litsea cubeba(Lour.)Pers.were determined by the national standard method,in order to provide a basis for the development and utilization of Litsea cubeba resources.The results showed that,the content of fat and crude fiber in Litsea cubeba fruit was obviously higher than those in leaves;the contents of protein,carbohydrate and vitamin C in Litsea cubeba leaves were obviously higher than those in fruits.Litsea cubeba oil mainly existed in Litsea cubeba fruit.The contents of phosphorus,zinc,copper and potassium in Litsea cubeba fruit were higher,and the contents of iron,manganese,selenium,calcium and magnesium in Litsea cubeba leaves were higher.The amino acid composition of Litsea cubeba fruit and leaves was similar,and the value of the essential amino acid in fruit was lower than that in leaves.Generally speaking,Litsea cubeba fruit and leaves contained essential oils,which could be used for the extraction of essential oils.At the same time,they were rich in nutritional value and had the potential to be developed into food.
