Cytotoxicity Activity of Biotransformed Ethyl p-methoxycinnamate by Aspergillus niger

The extraction of Kaempferiagalanga rhizome using steam distillation and supercritical fluid extraction (SFE) carried out. After fractionation, the major compound of the K. galanga, ethyl p-methoxycinnamate (EPMC) was Aspergillus ethyl p-hydroxycinnamate (EPHC). The biological activity of EPMC and its biotransformed product (EPHC) established by activity on human breast cancer (MCF-7) cell line using MTT assay. Ethyl p-hydroxycinnamate (EPHC) was most cytotoxic at 1000 μg/mL percentage cell viability was 9.87% IC50 was 340μg/mL. showed slight cytotoxicity activity compared to EPMC. that the biotransformation process was able to produce metabolite (EPHC) higher cytotoxicity activity compared to its parent compound (EPMC).
