Abstract

Cytotoxic assay of secondary metabolite endophytic fungus 1.2.11 from Brucea javanica (L) Merr has been carried out. Brucea javanica fruit collected from Cianjur was used in this experiment. Cytotoxic assay was done on Raji, NS-1, HeLa and Vero cells. The observation was done for 24 hours and also for 48 hours. IC50 was calculated using the Rich and Muench theory. To observe the working mechanism of cytotoxic process, DNA staining with etidium bromide and acridine orange was conducted. The cytotoxic assay of endophytic fungi 1.2.11 showed an IC50 of 58.35 μg/ml, 88.39 μg/ml on Raji cell,; 162.09 μg/ml, 66.24 μg/ml on NS cell; 361.21 μg/ml, 219.97 μg/ml on HeLa cell; and lastly 1075.18 μg/ml, 656.82 μg/ml on Vero cell after 24 and 48 hour incubation respectively. The results of this study showed that secondary metabolite of endophytic fungus 1.2.11 has selective cytotoxic effect towards cancer cell and also showed that it might cause apoptosis in NS-1cell.

Abstract

Macaranga known locally as mahang-mahangan has uniquely ecological function, and also became a part of traditional medicine in Indonesia. Macaranga genus also known as a sources of terpenoid and phenolic (flavonoid) compounds which have biological activity as antioxidant and anticancer (cytotoxicity).There are few phytochemical investigations have been done on M. gigantifolia species. As a part of our continuing research of isolation anticancer compound from natural product, a geranylated flavonoid compound (macarangin) has been isolated from ethyl acetate fraction of Macaranga gigantifolia leaves using chromatography methods. The isolated compund (isolat MG) was elucidated to gain the chemical structure based on spectroscopic data (LC-MS and FT-NMR). Cytotoxicity test of this compound was tested against MCF 7 cell lines, showed that macarangin has a potential activity with IC50 value 119.12μg/mL. Key words: Macarangin, geranylated  flavonoid, Macaranga gigantifolia, MCF 7 cell lines.
