This research paper consists of three chapters . The first chapter deals with the chemical composition of the the rust gross Flemingia (Flemingia ferruginea Grah. Ex Wall.) Roots . Experimental by plant chemical methods , from extremely heavy rust hair pulling samples were obtained 16 compounds were nine of flavonoids , a color original ketones . They are beta - bean sterols ( 1 ) , stigmasterol -3-β-OD- pyran- glucoside ( 2 ) , the beta - daucosterol ( 3 ) ,5 -hydroxy - 8 - gamma, gamma - dimethylallyl - 6 ' ' , 6 '' -dimethyl - pyrano ( 3 '' , 2'' : 6, 7 ) chromone ( 4 ) , 5 , 7 - dihydroxy-6 , 8 - isopentenyl primary colors of the original one ( 5) , 3 , 5, 7, 3 ' , 5' - hydroxy -4'- methoxy - based flavan ( 6 ) , flemichin D ( 7 ) , 5,7,4' - genistein (8) , 5, 7 , 3 ' , 4'- hydroxy- isoflavone (9 ) , the Mans handle isoflavones ( 10) , daidzein (11 ) , 5, 7, 4'- trihydroxy- isoflavone - 7 - O - beta - D - glucopyranoside ( 12 ) , 5 - hydroxy -4'- methoxy - 7 -O - beta- D - pyran- glucoside ( 13) , 5, 7 , 4' - trihydroxy- isoflavone - 7 -O - beta -D - Qin sugar yl - ( 1 → 6 ) - beta - D grape pyran- glucoside ( 14) , methylparaben ( 15 ) , betulinic acid ( 16 ) . The main components were represented by seven isoflavone genistein , prevention and treatment of breast cancer , prostatitis , and cardiovascular and cerebrovascular disease , the main active ingredient is Flemingia genus . ? The second chapter discusses floral (Anthocephalus chinensis Rich. Ex Walp.) The chemical composition of the bark . By plant chemical methods , in the experiment were found 10 compounds , sterol beta - beans ( 1 ) , beta- daucosterol ( 2) , oleanolic acid (3) , ursolic acid ( 4 ) , clethric acid ( 5 ) antiarol ( 6 ) , benzoic acid ( 7) , 3, 4 - dihydroxy- benzoate ( 8 ) , 2 , 4 - dihydroxy-6 - methyl- benzoic acid ester ( 9) , Kadan Bin ( 10 ) . Wherein the compound is 5,8 and 9 for the first time from this plant isolated , isolated from a large number of Kadan Bin , strong and long-lasting blood pressure lowering effect with good development prospects . Chapter III through data analysis, the anti-tumor activity of flavonoids and alkaloids , which myrtifolic acid , 5,7,4 ' - genistein , 5 , 7 , 4'- hydroxy -8,3 ' - di-iso- flavanone -pentenyl , 5 , 7,4 ' - 3 hydroxy-6- isopentenyl isoflavone lespedezaflavanone a shows cytotoxic activity . ??
