P. indica has been used in folk medicine in Southeast Asia including Thailand. Its leaves are used as a nerve tonic and for treating inflammation and the bark in decoction form against hemorrhoids. Additionally, P.indica leaves are used in the preparation of a herbal tea consumed for promoting good health. However, the characteristics of herbal tea are undescribed. Currently, The study of the biological activity in a number of Khlu. It has been reported that Khlu that each region has different antioxidant or not. This study aimed to study the effect of the tea Khlu in each area to volume ratio of phenol and flavones affect overall activity of free radicals. By examining the antioxidant properties of extracts from tea leaves Khlu in the three areas and extracts from tea leaves Samutsakorn Khlu, Udon Thani Khlu. And Chanthaburi Khlu of the both extracted water and the extraction of ethanol. The results showed that the extracts from tea Khlu from Chanthaburi extracted with water and ethanol have the most effective DPPH radicals. The IC50 DPPH radical elimination of the extracted water is equal 0.0257 ± 0.02 mg per mL, and the extraction with ethanol is equal to 0.2007 ± 0.02 mg per mL, respectively. The extract water of tea Kloe from Chanthaburi is also capable of reducing the highest was 175.5 ± 0.01 mg gallic acid equivalent/g extract. The tea leaves Khlu ethano extract from Udon Thani is capable of reducing the high is 80.39 ± 0.00 mg gallic acid equivalent/g extract. But the tea leaves Khlu water extraction of three areas was percentages of metal chelating no different. The three areas of Kloe tea ethanol extract. Found that tea Khlu from Udon Thani has the highest percentage of chelating metals.
