Abstract:
Objective To study the constituents in Melicope pteleifolia. Methods Plant material was isolated with 80% EtOH. Compounds were separated with chromatographic methods and their structures were elucidated on the basis of spectral analysis (EI-MS, 1H-NMR, and 13C-NMR) and chemical evidence. Results Five compounds were isolated from petrol ether or ethyl acetate soluble fraction. Their structures were identified as 3,5,3'-trihydroxy-4'-methoxy-7-(3-methylbut-2-enyloxy) flavone (pteleifolosin C, 1), 3,7-dimethoxyl kaempferol (kamatakenin, 2), vanillic acid (3), tricosanoic acid tetradecyl ester (4), and p-sitosterol (5), respectively. Conclusion Compound 1 is a new structure named pteleifolosin C. Compounds 2-4 are isolated from this plant for the first time.
