ABSTRACT
OBJECTIVE:
To study the chemical constituents of the fruits of Embelia laeta.METHODS:
The compounds were isolated and purified by MCI, medium pressure TLC on silica gel column, ODS column chromatography, semi-preparative HPLC, and so on. The structures were elucidated on the basis of various modern spectroscopic techniques using physical, chemical properties and spectral data.RESULTS:
Fifteen compounds were isolated and identified as nantenine(1), oxonantenine(2), physcion(3), syringic acid(4), vanillic acid(5), stigmast-4-ene-3,6-dione(6), (+)-lyoniresinol(7), 75,85-threo-4,7,9,9'-tetrahydroxy-3,3'-dimethoxy-8-O-4'-neolignan(8), 1,3-dihydroxylpropyl-(9Z,12Z)-octadeca-9,12-dienate(9),(22E)-5a,8a-epidioxyergosta-6,22-dien-3b-ol(10), dihydroxyisoechinulin A(ll), hydroxybenzoic acid(12), stigmasterol(13), sitosterol(14), and daucosterol(15).CONCLUSION:
Compounds 1,2, and 5-13 are isolated from the genus Embelia for the first time, and compounds 1-15 are isolated from this plant for the first time.
