Abstract: 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^-1 and 0. 21 mg·L^-1,respectively,and total flavonoids of 3. 88 mg·L^-1,3. 42 mg·L^-1 and 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.
