Abstract

Various diseases including cancer and cardiovascular diseases are induced by free radicals via lipid peroxidation, protein peroxidation, DNA damage, and cellular degeneration in the cells. Piper betle L., commonly called betel, belongs to the Piperaceae family. It originated from South and South East Asia, and has been used as a traditional medicine by people there due to its medicinal properties. In the present study, free radical scavenging activity of ethanolic leaves extract of Piper betle L. together with its different solvent fractions (hexane, ethyl acetate, butanol, and water) were evaluated by DPPH free radical scavenging assay. The ethanolic extract and the ethyl acetate fraction had shown very significant DPPH (1,1-diphenyl-2-picryl-hydrazyl) radical scavenging activity compared to the other fractions. In DPPH free radical scavenging assay, the IC50 value of the ethanolic extract and the ethyl acetate fraction were found to be 17.43µg/mL and 11.53 µg/mL, respectively. The free radical scavenging activity was assumed due to the total phenolic content. The total phenolic content was found to be highest in the ethanol extract (277.68 μg EGCG/mg) and the ethyl acetate fraction (559.38μg EGCG/mg). The results concluded that the ethanolic leaves extract of Piper betle L. and its ethyl acetate fraction have a considerably free radical scavenging activity.Keywords: Piper betle L., Piperaceae, free radical scavenging, DPPH

Abstract

Drug discovery for cancer medication is the most important effort that researcher do at this time. Indonesia bio diversities have possibility as a cancer medicine sources. Finding a herbal medicine for cancer treatment is a first step to find a right cancer medicine in the future. This research has already completed for the earlier another research. Some fractions of Hedyotis corymbosa extract has been analyzed using Sulforhodamine B method with UV wavelength 515 nm against T47D cell line, a human breast cancer. There are Hexane extract, Methylene chloride extract and Ethyl acetate extract, and give inhibitory concentration 50 (IC50)  of 33.45 µg/ml, 54.59 µg/ml and 52.58 µg/ml, respectively. Ethanolic extract, itself has IC50 of 61.57 µg/ml, whereas IC50 value of Cisplatinum is  9.63 µg/ml. There is a difference between the ethanolic extracts with the other fraction.Keywords: breast cancer, herbal medicine, T47D, Hedyotis corymbosa
