Two Diarylundecanones Isolated from Ardisia tenera

Ardisinones G-H (1–2), two new diarylundecanones, were isolated from the ethanol extract of aerial parts of Ardisia tenera Mez. Their structures were elucidated by interpretation of the spectroscopic evidence. The isolated compounds were evaluated for cytotoxicity against four cell lines (MV4–11, MCF-7, HCT116 and A549) and displayed moderate inhibitory activities.
