  • Exploration of secondary metabolites was the focus of this research, especially of Artocarpus calophylla species to look for a potential cytotoxic agent. An arylbenzofuran derivative compound, namely heterophyllene A was isolated from the stem bark of Artocarpus calophylla. Structure determination of this compound has been elucidated using UV-Vis spectroscopy, 1D, and 2D NMR analysis. This compound has a lower IC50 than ethyl acetate extract. The IC50 of this compound (57,54 μg/mL) to HeLa and (25,80 μg/mL) to T47D cells, ethyl acetate extract (>100 μg/mL) to HeLa and (84,16 μg/mL) to T47D cells.
