Sari

The influence of solvents on the gaining of phenolic compounds and antioxidant activity of  meniran herbs (Phyllanthus niruri L.)  have been evaluated. The meniran herbs were extracted with  methanol-water, ethanol-water and acetone-water. Total phenolic content of these extracts were determined by using the Folin-Ciocalteau method and antioxidant activity of these extracts were determined by using  DPPH method. The results showed that extraction with methanol-water, ethanol-water and acetone-water give extractives in ammount of 167.9, 152.8 and 135.7 mg/g, respectively. The total phenolic compound content of these extracts were 73.4584, 59.9798 and 48.9976 mg/g respectively. Where as the antioxidant activity (IC50 value) of these extract were 0.3987,  0.4323 and 0.4495 mg/mL, respectively.
