Total phenolic (TP) contents of betel leaves measured using Folin-Ciocalteu’s colorimetric method are presented in Table 1. The TP contents of betel leaf extracts ranged from 59.38 to 202.92 mg GAE/g and 58.54 to 205.20 mg GAE/g using ethanol and methanol solvents, respectively. The TP values of acetone- and ethyl acetate-extracted samples ranged from 47.68 to 191.50 mg GAE/g and from 46.45 to 128.43 mg GAE/g, respectively. In waterextracted samples, the TP content was 71.30 mg GAE/g.
