Abstract

One new diarylpentanone, 4(S)-hydroxy-1, 5-diphenyl -2(E)-en-1-pentanone (1), two diarylpentanones isolated from Wikstroemia indica for the first time (3 and 5) and two other known diarylpentanones were isolated from petroleum ether fraction of root of Wikstroemia indica. The structure of the new compound including absolute configuration was elucidated by extensive spectroscopic techniques, including 1D, 2D NMR, HR-ESI-MS and ECD spectroscopy. All isolated compounds were tested for their cytotoxic activity against cancer-derived cell lines A549. Compound 5 exhibited remarkable cytotoxic activity comparable to that of positive control cisplatin.
