Compositional Analysis of Leaves of Maple(Acer tegmentosum Maxim.)and Study on Antioxidant Capacity of Its Extracts
The general constituent content,free sugar content and antioxidant capacity study of the leaf extracts of Acer tegmentosum Maxim.were investigated using the leaves of Acer tegmentosum Maxim.as raw material.The antioxidant capacity of ATWE and ATEE was determined using DPPH radicals,ABTS+radicals,scavenging capacity of superoxide anion and ferric ion reducing capacity as evaluation indexes.The results showed that the moisture of the leaves of Acer tegmentosum Maxim.was 13.24％,crude ash content was 4.73％,crude fat content was 5.41％,protein content was 19.77％,carbohydrate content was 56.85％,and the total dietary fiber content was 49.57％;Three kinds of free sugars were detected in the leaves of Acer tegmentosum Maxim.,including fructose,sucrose,and glucose with 5.13％,1.38％and 3.45％,and maltose and lactose were not detected.The results showed that both ATEE and ATWE possessed good free radical scavenging and reducing ability,and in general,the antioxidant capacity of ATEE was better than that of ATWE.
