Antioxidant Activity from Baccaurea lanceolataMuell. Arg fruit

Abstract

Abstract. Fruits of Baccaurealanceolata is commonly used by tribe banjar in south Borneo to protect the skin damages due to sun light. People apply the pulverized fruits to the skin that will be exposed to sunlight. Antioxidant bioassay method (DPPH) is used to prove the effectiveness of the fruits.Baccaurealanceolata fruitsvwere extractedby 70% ethanol, followed by fractionation with n-hexane, ether, ethyl acetate and methanol to give n-hexane (fr-H), ether (fr. Et2O), ethyl acetate (fr.EtOAc) and methanol (fr. MeOH) fractions respectively. Preparative TLC (SiO2) of the fr.EtOAc that showed the the highest antioxidant activity among those fractions. This compound was active as antioxidant 1.124 mg/ml.
