Abstract:
This research aims to study bioactivity of leaf, inflorescence and branch extracts from Acacia auriculiformis that has been used as forest plantation in Thailand. The extracts were evaluated of antioxidant activities by DPPH scavenging method, branch extract gave the best 50 percent Inhibition Concentration (IC50) at 19.36 mg/ml. To find out total phenolic contents, branch extract had the highest total phenolic contents at 597.22 mg GAE/g extract. Antibacterial studied of extracts against five bacterial strains; Escherichia coli TISTR 780, Staphylococcus aureus TISTR 1466, Micrococcus luteus TISTR 2374, Bacillus cereus TISTR 687 and Xanthomonas campestrispv.campestris TISTR 2065. The result of antibacterial activity using agar well diffusion method was found that all of extracts could not inhibit the growth ofE. coliwhileleaf, inflorescence and branch extract could inhibit the growth ofother four bacterial strains S. aureus, M. luteus B. cereus and X. campestrispv campestris. And MIC studied found thatinflorescence extract used the lowest concentration to inhibit the growth ofS. aureus, M. luteus, B. cereus and X. campestrispv campestris. According to the bioactivities results, branch and inflorescence extracts of A. auriculiformis have potential for remedy aspects to add value of this plant.
