摘要(Abstract):

[Objective] To isolate and detect the antioxidants in the dried leaves of Malus melliana( Hana-Mazz) Rehd. [Methods] Isolation and purification were carried out by silica gel,Sephadex LH-20 chromatography,and recrystallization. According to the physicochemical properties,spectra data and relevant literatures,the structure of monomer was identified. A total of 9 chemical components were isolated from the ethyl acetate part of dried leaves of M. melliana,which were β- sitosterol( 1),daucosterol( 2),oleanolic acid( 3),ursolic acid( 4),arjunolic acid( 5),chrysin( 6),phloridzin( 7),trilobatin( 8) and isoetin 5'-glucoside( 9). [Conclusions] The chemical components mentioned above were isolated from the plants for the first time. Chemical compound 5 was firstly isolated from the plant of genus Malus; and chemical compound 9 was firstly isolated from the plant of family Rosaceae.
