摘　　要：紫苏(Perilla frutescens)是我国传统的药食兼用型植物。本研究对药用紫苏M424和油用紫苏M84的叶中主要营养及药用成分进行检测分析。结果发现:M424与M84两种紫苏叶片中氨基酸种类齐全,蛋白含量分别为8.62%及12.67%,显著高于常见叶菜,必需氨基酸占总氨基酸含量比值(EAA/TAA)及必需氨基酸与非必需氨基酸的比值(EAA/NEAA)均达到理想蛋白的标准。2种紫苏叶片中纤维素含量分别为23.84%和18.60%,总糖含量分别为2.84%和2.08%,脂肪含量分别为1.53%和2.39%。2种紫苏叶矿物质元素含量丰富,其中钙、铁和硒含量均显著高于普通叶菜。β-胡萝卜素含量分别为0.38和0.32 mg·g^(-1),维生素C含量3.27和3.03 mg·g^(-1)。2种紫苏叶挥发油含量约为0.765%及0.312%。药用紫苏的迷迭香酸、总黄酮及花青素等抗氧化成分含量均高于油用紫苏;而油用紫苏叶片中蛋白及脂肪含量较高。Perilla(Perilla frutescens)is a traditional edible and medicinal plant in China.In this study,the main nutritional and medicinal components of medicinal perilla M424 and oil perilla M84 leaves were detected and analyzed.The results showed that the amino acids in the leaves of M424 and M84 were complete,and the protein contents were 8.62%and 12.67%respectively,which were significantly higher than those of common leafy vegetables.The ratio of essential amino acids to total amino acids(EAA/TAA)and the ratio of essential amino acids to nonessential amino acids(EAA/NEAA)reached the standard of ideal protein.The contents of cellulose,total sugar and fat of medicinal perilla and oil perilla were 23.84%and 18.60%,2.84%and 2.08%,1.53%and 2.39%respectively.The contents of calcium,iron and selenium in the leaves of two kinds perilla were significantly higher than those of common leafy vegetables.The contents ofβ-carotene and vitamin C were 0.38 and 0.32 mg·g^(-1),and 3.27 and 3.03 mg·g^(-1),respectively.The contents of volatile oil in the leaves of two kinds perilla were about 0.765%and 0.312%.The contents of rosmarinic acid,total flavonoids and anthocyanins in medicinal perilla were higher than those in oil perilla,and the contents of protein and fat in oil perilla leaves were higher.
