Abstract

Five O-geranylated coumarins namely as auraptene (1), 7-((2’E,6’E)-5’-hydroxy-3’,7’-dimethylocta-2’,6’-dienyloxy)coumarin (2), 7-(2’E,5’E)-7’-hydroxy-3’,7’-dimethylocta-2’,5’-dienyloxy) coumarin (3), 6-methoxy-7-oxygeranylcoumarin (4), and 8-oxygeranylpsoralen (5) were isolated from the roots of Limonia accidissima L. Their structures were determined based on spectroscopic data such as UV, IR, MS and NMR. Compounds 1–5 were evaluated for their radical scavenging against 2,2-diphenyl-1-picrylhydrazyl (DPPH), showing their IC50 were 462; 13; 260; 210 and 234 µg/ml, respectively. Keywords: Limonia accidissima L., O-geranylated coumarins, antioxidant activity, DPPH

Abstract

Two furoquinoline alkaloids, leptanoine C (1) and haplopine-3,3´-dimethylallyl ether (2) were isolated from the leaves of Melicope moluccana. The chemical structure of both compounds was determined based on spectroscopic data, including UV, IR, HR-ESI-MS, 1D, and 2D NMR spectral data. The antimalarial activity of compounds 1-2 against Plasmodium falciparum 3D7 showing their IC50 values are 0.18 ppm and 2.28 µg/mL, respectively.
