    In this study, Peperomia pellucida was subjected to the determination of biological activity and isolation of chemical constituents. Two samples of this plant were used, which were the air-dried and freeze-dried. The sequential maceration of the plant utilized three different solvents with increasing polarities, namely dichloromethane, ethyl acetate and methanol. The Thin Layer Chromatography (TLC) profile showed there was no significant different in the chemical constituents in both samples.
