The free radical scavenging property and antimicrobial activity of Triphala- the herbal product made of equal proportion of Terminalia chebula, Terminalia belerica and Emblica officinalis, were evaluated. Ethanol extracts of the formulation were tested for its total antioxidant activity using improved ABTS radical cation decolorizing assay and antibiotic assay against Streptococcus mutans (predominantly involved in bio-film formation on human teeth). An effort was also made to correlate its antiplaque activity using an in-vitro assay (conditions were kept similar to oral cavity) with Triphala and two commercial toothpastes (Product 1 and product 2). The herbal extract effectively inhibited the bio-film formation and the better antioxidant activity exhibited by the extract might protect the gum cells effectively from free radicals than the commercial toothpastes. Thus Triphala can be used as an effective antiplaque agent.
Keywords: ABTS, antiplaque, Terminalia, triphala.
