From EtOAc-soluble fraction of the aerial parts of (Vitaceae), two new meroterpenoids named ampechromonol A () and ampechromonol B (), together with five known compounds (-), were isolated. Their structures were elucidated based on NMR spectroscopic analysis. The plausible biosynthesis pathway for the formation of two new meroterpenoids was proposed. This research is the first isolation of meroterpenoids from genus. Compounds and showed weak cytotoxicity against MCF-7 breast cancer cells.
