摘　　要：以小叶榕(Ficus microcarpa L.)气生根为研究对象,在测定其不同部位的总酚酸及总黄酮含量的基础上,选用DPPH和ABTS 2种体外抗氧化评价方法比较不同部位的抗氧化活性。结果表明:首部的总酚酸和总黄酮含量高于其他部位,其总酚酸含量分别为首部0.34 mg·L-1,中部0.31 mg·L-1,尾部0.21 mg·L-1;总黄酮含量分别为首部3.88 mg·L-1,中部3.42 mg·L-1,尾部2.91 mg·L-1。抗氧化活性首部最强,中部次之,尾部较弱。总酚酸的含量和抗氧化活性之间具有很高的相关性,表明抗氧化活性可能与酚酸类物质有关。Different parts of aerial roots of Ficus microcarpa L. were collected to determine their content of total phenolic acids and total flavonoids,and the antioxidant activities of the extracts of different root parts were tested by using the DPPH and ABTS methods for assessment of in vitro free radical scavenging activities. Results showed that the top part of the roots contained the highest total phenolic acids and flavonoids,and that the top,middle and bottom parts of the roots contained total phenol of 0. 34 mg·L^-1,0. 31 mg·L^-1and 0. 21 mg·L^-1,respectively,and total flavonoids of 3. 88 mg·L^-1,3. 42 mg·L^-1and 2. 91 mg·L^-1,respectively. The top root part contained the highest antioxidant activity,followed by the middle and bottom root parts. Total phenolic acids were highly correlated with antioxidant activity,which indicates that the antioxidant activity might be related to phenolic acids.
