A Comparative Study on Antioxidation and Antibacterial Activities Triphala Herb Extracts from Chae Son, Lampang, Thailand

Introduction: Triphala, a herbal medicine which is a product from Chae Son, Lampang, Thailand, is an unequal-proportional mixture of fruits of three herbs, Phyllanthus emblica, Terminalia chebula, and Terminalia bellirica (2:1:1).

Materials and Methods: The contemporary study concentrated on extracts detection and comparative analysis between various annual year (A.D.2017/2018) activities in hexane, ethyl acetate, and methanolic extracts of Triphala. The determination of antioxidant was using by 1,1-diphenyl-2-picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP). The broth dilution and agar well diffusion assay were determined antibacterial.

Results: Results exposed the valuable biological activity extracts from ethyl acetate and methanol solvents of T. chebula and T. bellirica, which strength is accountable for biological activities. Extracts displayed acceptable radical-scavenging activity analogous with ascorbic acid. The methanol extract of T. bellirica (0.0013 mg/mL), ethyl acetate extract of P. emblica (0.0009 mg/mL), in A.D. 2017 and the ethyl acetate extract of P. emblica (0.0090 mg/mL), the methanol extract of Triphala (0.0176 mg/mL) in 2018, were exhibited higher antioxidant activity. Also, extracts indicated hopeful antibacterial potential against tested strain comparable to chloramphenicol.

Conclusion: The results in A.D. 2017 showed that inhibition zone of P. emblica in ethyl acetate extract; S. aureas (8.67 mm), E. aerogenes (8.67 mm), E. coli (EPEC) (7.67 mm), P. mirabilis (7.73 mm) , S. typhimurium (8.33 mm), S. flexneri (8.33 mm) and V. cholera (7.33 mm) together with P. emblica methanol extract; S. aureas (6.67 mm), E. aerogenes (7.76 mm.) and V. cholera (4.0 mm). Therefore, it could be concluded that Triphala may be a talented candidate in pharmaceutical and future medicine.
