Abstract Triphala is an anti-oxidant-rich herbal formulation containing fruits of Emblica officinalis, Terminalia chebula and T. belerica in equal proportions. The preparation is frequently used in Ayurvedic medicine to treat diseases such as anaemia, jaundice, constipation, asthma, fever and chronic ulcers. Anti-mutagenic effects of the polyphenolic fractions isolated from Triphala have been reported, thus indicating that the phenols present in the formulation might be responsible for its therapeutic efficacy. A simple high-performance liquid chromatography method for the separation and quantitative determination of the major antioxidant polyphenols from Triphala has been developed. The use of an RP18 column with an acidic mobile phase enabled the efficient separation of gallic acid, tannic acid, syringic acid and epicatechin along with ascorbic acid within a 20 min analysis. Validation of the method was performed in order to demonstrate its selectivity, linearity, precision, accuracy and robustness. In addition, optimisation of the complete extraction of phenolic compounds was also studied. Copyright 2007 John Wiley & Sons, Ltd.
