Nielsen) pods by using DPPH method. The IC50 of extracts obtained from linear regression equation on chart concentration vs % inhibition. Pods of jiringa dried at room temperature 1 x 24 h and then macerated with methanol. Filtrat were evaporated with rotary evapoarator to obtained methanol extract. Further, methanol extract dissolved with water and partitioned with ethyl acetate for several times, and then evaporated to obtained ethyl acetate extract. Ethyl acetate extract partitioned with methanol and n-hexane to obtained n-hexane extract and total phenolic.
