Abstract:
The open silica gel, ODS, and Sephadex LH-20 column chromatography, along with the semi-preparative HPLC was used to isolate and purify the chemical constituents from Murraya euchrestifolia. The structures of the isolates were elucidated by their physiochemical properties, NMR, and MS spectroscopic data, as well as comparison with literature data. Eighteen compounds were isolated from the CH2Cl2 fraction of the 95% aqueous EtOH extract of M. euchrestifolia, and their structures were identified as sakuranetin (1), eriodictyol-7,4'-dimethyl ether (2), isosakuranetin (3), 5-hydroxy-7,4'-dimethoxyflavanone (4), eriodictyol-7-methyl ether (5), lichexanthon (6), 5,6,7-trimethoxycoumarin (7), 5-hydroxy-6,8-dimethoxycoumarin (8), 8-hydroxy-6-methoxy-3-n-pentylisocoumarin (9), ethyl caffeate (10), 4-hydroxy-3,5- dimethoxycinnamic acid ethyl ester (11), methyl 3-(5'-hydroxyprenyl)-coumarate (12), (E)-coniferol (13), β-hydroxypropiovanillone (14), 3-hydroxy-7,8-didehydro-β-ionone (15), 3β-hydroxy-5α, 6α-epoxy-7-megastigmen-9-one (16), grasshopper ketone (17), and 4-hydroxy-3,5-dimethoxybenzaldehyde (18). Compounds 1-15 and 18 were first obtained from the plants of Murraya genus, and compounds 16 and 17 were isolated from M. euchrestifolia for the first time.
