Effects of ratios of ethanol-water as extracting solvent in obtaining extractable material, phenolic 'compounds and antioxidant activity from the herb of Phyllanthus niruri Linn. have been investigated. The ratios tested were 100:0, 80:20, 70:30, 60:40 and 50:50. The results revealed that the ratio of ethanol-water used gave significant effect on extractable material, phenolic compounds and ant…
