Isolation of Active Compounds from Original Plants of East Kalimantan as Cosmetics

Abstract

Phytochemical and antioxidant activity tests were conducted on ethanol extracts of the trunk, flower and leaf of Senggani (Melastoma candidum D.Don). Each sample was macerated with ethanol, and then it was concentrated with a rotary evaporator. The secondary metabolites of each sample's phytochemical test (Senggani) showed that the ethanol extract taken from the trunk was phenolics and triterpenoids. In contrast, the sample taken from the flower were steroid, and from the leaf were saponins. The result showed that in ethanol extract taken from the trunk exhibited antioxidant activities subtuance at 39.087 %, the ethanol extract from the flower was at 6.548 % and the ethanol extract taken from the leaf at 60.913 ± 0.002 µg/ml for the ethanol extract of the trunk, EC50 µg/ml at 93.452 ± 0.005 µg/ml for the ethanol of the flower and , EC50 (µg/ml) at 42.063 ± 0.015 µg/ml for the ethanol of the leaf.
