Two novel coumarins bearing an acetophenone derivative from the leaves of Melicope Quercifolia
Meliquercifolins A (1), and B (2), two new coumarins are bearing an acetophenone derivative were isolated from the leaves of Melicope quercifolia along with three known compounds, melicodenines E (3), F (4)andI(5). Structures of two new compounds were identified based on spectroscopic analyses (UV,...

| Summary: | Meliquercifolins A (1), and B (2), two new coumarins are bearing an acetophenone derivative were isolated from the leaves of Melicope quercifolia along with three known compounds, melicodenines E (3), F (4)andI(5). Structures of two new compounds were identified based on spectroscopic analyses (UV, HR-ESI-MS, 1 D and 2 D NMR). Cytotoxic activities of compounds (1–5) towards three human cancer cells (HeLa, MCF-7, P-388), compounds 1, 4 and 5 showed very potent activity against Hela cells with IC 50 values 2.6; 0.8; 1.1 lM, respectively. |
