Title: Study on triterpenoid and flavonoid contents of Rabdosiajaponica
Abstract: Objective To extract and identify the chemical constituents of Rabdosia japonica.Methods The constituents were isolated and purified by chromatography on silica gel,Sephadex LH-20and HPLC.The structures of the compounds were determined by mass spectrometry(MS)and nuclear magnetic resonance(NMR)spectra1analysis.Results Totally 10 compounds were isolated and their structures were identified as four triterpenoids:oleanolic acid(1),ursolic acid(2), 2α-hydroxyursolic acid(3),2α,23-dihydroxyursolic acid(4);six flavonoids:quercetin(5),apiginin(6),luteolin(7),rutin(8),isorhamnetin(9),and tricin(10).Conclusion Isorhamnetin(9)and tricin(10)had been isolated from this plant for the first time
