摘要：

The methanol and aqueous extracts of Piliostigma reticulatum barks were investigated for its antioxidant and antibacterial activities. The antioxidant test using 1,1-diphenyl-2-picrylhydrazyl (DPPH) method demonstrated important radical scavenging activity for the methanol extract with IC50 = 0,37 +/- 0,04 mu gmL(-1). The 2 extracts were then examined for antibacterial activity by using the broth micro dilution method. The extracts possessed the antibacterial effect against the almost germs tested; the aqueous extract exhibited a better activity than methanol extract. These results indicate that methanol and aqueous extracts of P. reticulatum could be used as a source of antioxidant and antibacterial ingredients in the food industry.
