The antioxidant activities of two groups of Homalium paniculiflorum stem extracts, accelerated solvent extracts and conventional solvent extracts, were evaluated respectively with microplate reader, by DPPH method and FRAP method, taking ascorbic acid (Vc), butylated hydroxytoluene (BHT) and rutin (Rutin) as positive controls. Results showed that among these extracts, ASE-EtOAc extract had the strongest (yet weaker than all positive controls) capacity of DPPH free radical scavenging (EC50=20.8 μg/mLASE-DCM had the strongest (stronger than BHT yet weaker than Vc and Rutin) reduction capacity of Fe3+(FRAP value=793.3±45.7 mol TE /g);conventional water extract W displayed the weakest capacity in either DPPH free radical scavenging or Fe3+ reducing. Judging from comprehensive comparison, conventional NBA extract has better applied prospect and is worthy of extensive research, for it is easily prepared and has noticeable antioxidant ability.
