ABSTRACT
This article was aimed to study the chemical constituents of Dioscorea opposita Thunb.The chemical constituents were isolated and purified by Diaion HP-20,Toyopearl HW-40,Sephadex LH-20,MCI Gel CHP-20,silica gel column chromatography and preparative HPLC,TLC,purification and isolation from Dioscorea opposita Thunb.The structures of isolated compounds were identified by thc physicochemical properties and spectral analysis.The result showed that 14 compounds were isolated from Dioscorea opposita Thunb.The chemical structures were elucidated as L-Tryptophane (1),Seguinosides F (2),1-methoxycarbonyl-β-carboline (3),Helichrysin A (4),Bungein A (5),Hydroquinone (6),Zarzissine (7),Cyclo-(Pro-Thr) (8),4-Hydroxy-3-methoxybenzyl alcohol (9),pyridine-3-carboxamide (10),Arbutin (11),Methyl syringate 4-O-β-D-glucopyranoside (12),L-Phenylalanine (13),1,2-benzenedicarboxylic acid,1,2-bis[2-(2-hydroxyethoxy) ethyl] ester (14).It was concluded that chemical compounds 1-14 were isolated for the first time from Dioscorea opposita Thunb.
