Abstract:
Objective:The different parts of Psidium guajava(Myrrhinaceae) have different bioactivities. There are intensive studies for chemical constituents of its leaves and fruits at present. However,there are a few studies for the roots. Therefore, we systematically investigated the chemical constituents of phenolic acids in roots of P.guajava. Method:The chemical constituents were isolated and purified by various column chromatography methods and semi-preparative HPLC. The isolated compounds were identified by physicochemical properties and spectral analysis. Result:Sixteen phenolic components were isolated from the ethanol extract and identified as 3,3',4'-tri-O-methylellagic acid(1),3,3',4-tri-O-methylellagic acid-4'-O-β-D-glucopyranoside(2),3-O-methylellagic acid-4'-O-α-L-rhamnopyranoside(3),3'-O-methyl-3,4-O,O-metheneellagic acid-4'-O-β-D-glucopyranoside(4),gallic acid(5),methyl gallate(6),ethyl gallate(7), 3,4,5-trimethoxypheny-1-β-D-glucopyranoside(8),3,5-dimethoxy-4-hydroxy-benzoic acid-7-O-β-D-glucoside(9),1-hydroxy-3,4,5-trimethoxyphenyl-1-O-[6'-O-(4″-carboxy-1″,3″,5″-trihydroxy)phenyl]-β-D-glucopyranoside(10),vanillic acid(11),protocatechuic acid(12),secoisolariciresinol 9-O-β-D-glucopyranoside(13),phloretin 4'-O-β-D-glucopyranoside(14),cinchonain Ib(15) and epicatechin(16). Conclusion:Compounds 3,4,6,8-10,13-15 were isolated from this plant for the first time.
