RESUMEN
AIM To study the chemical constituents from Phyllodium pulchellum (L.) Desv..METHODS The ethyl acetate and n-butanol fractions of P.pulchellum 95％ ethanol extract were isolated and purified by Sephadex LH-20,silica,ODS and pre-HPLC column,then the structures of isolated compounds were identified by physicochemical properties and spectral data.RESULTS Eleven compounds were isolated and identified as phydroxybenzoic acid (1),protocatechuic acid (2),protocaechuic acid methyl ester (3),protocatechuic acid ethyl ester (4),ethyl gallate (5),p-coumaric acid (6),caffeic acid ester (7),loliolide (8),uridine (9),arbutin (10),daucosterol (11).CONCLUSION Compounds 4-11 are isolated from genus Phyllodium for the first time,compounds 2 and 3 are first obtained from this plant.
