摘　　要：以42份不同种质藏茴香的幼嫩叶片为试验材料,对其维生素C、总糖、氨基酸等营养成分进行测定,比较不同种质间的营养成分含量差异,并进行相关性分析和营养品质评价。结果表明,藏茴香叶片维生素C平均含量为485.2 mg/kg,氨基酸1817.7 mg/kg,总糖118.4 g/kg,可溶性蛋白质71.9 g/kg,纤维素545.3 mg/kg。不同藏茴香种质资源叶片的营养成分存在一定的差异性,维生素C、氨基酸和总糖的变异系数大,可溶性蛋白质变异系数小。相关性分析结果表明,维生素C、总糖的含量与海拔呈负相关,氨基酸、可溶性蛋白质和纤维素的含量与海拔呈正相关,其中纤维素含量与海拔呈显著正相关。同时,用隶数函数法对42份藏茴香种质资源叶片的营养品质进行评价,将其营养品质分为4个等次。The leaves of 42 germplasm of Carum carvi were used as experimental materials,the nutritional components such as vitamin C,total sugar and amino acid were determined,the differences of nutritional components among different germplasm were compared,and the correlation and the nutritional quality was analyzed.The results showed that the average content of vitamin C,amino acid,total sugar,soluble protein and cellulose respectively was 485.2 mg/kg,1817.7 mg/kg,118.4 g/kg,71.9 g/kg,545.3 mg/kg.There were some differences in nutrient components in leaves of different Carum carvi germplasm resources.The coefficients of variation of vitamin C,amino acid and total sugar were large,while the coefficient of variation of soluble protein was small.The results of correlation analysis showed that the content of vitamin C and total sugars were negatively correlated with altitude,the content of amino acids,soluble protein and cellulose were positively correlated with altitude,and the content of cellulose was significantly positively correlated with altitude.At the same time,the nutritional quality of fresh leaves of 42 Carum carvi germplasm resources was evaluated by means of the log number function method,and the nutritional quality was divided into 4 grades.
