摘　　要：元宝枫叶含有黄酮、绿原酸、SOD活性酶、丙二醛和VC等多种生物活性物质。以2年生元宝枫苗为试材,对其进行不同光强处理,测定叶内黄酮、绿原酸、SOD酶、丙二醛和VC的含量。结果表明,不同光强处理对元宝枫叶内生物活性物质含量的影响十分显著,其中以60%自然光处理下的元宝枫叶黄酮含量最高,全自然光处理下绿原酸和VC含量最高,而45%自然光处理下的元宝枫叶SOD酶活性和丙二醛含量最高。综合来看,不同的光强处理对元宝枫叶内生物活性物质含量的积累是不同的。The contents of bioactive substances including flavonoids,chlorogenic acids,SOD enzyme,MDA,and VC in the leaves of two-year-old Acer truncatum seedlings were studied under different light intensities.The results showed that the different light intensities had obvious influences on the contents of bioactive substances in the leaves of A.truncatum seedlings.The content of flavonoids in the leaves treated with 60% light intensity was the highest and the contents of chlorogenic acids and VC in the leaves treated with 100% light intensity were the highest.While SOD enzye activity and MDA content in the leaves were the highest under 45% light intensity.Comprehensively,the accumulations of bioactive substances in the leaves of A.truncatum seedlings varied with the light intensities and the bioactive components.
