A study of some biological and chemical studies Of Mirabilis jalapa L

Abstract

This study included preperation cold alcoholic (Methanolic ) extract of the parts of Mirabilis jalapa L. and the extract percentage was determined , the result included ( 10.66 % ) and the extract was viscoid , soluble inwater . The detection on the active materials was done and the results were that the crude extract containsi Alkaloids , Tanrins , Glycosides , Saponins , Resins , Volatile oils , Terpens Steroids at pH = 5.5 The elements N,P, Ca , K , Mg , Fe , Mn , Na , pb , Cr Were also determined in plant ash . The results indicate that the plant contains : ash , Total lipids , Crude protein and Mucilage : ( 6.1 , 2.02 , 1.6 and 3.7 ) % respectively . The effect of the extract was applied on Staphy lococcus aureus and Escherichia coli at the Concentrations ( 200,100,75 , 50 ) mg / ml , and it showed inhibition activity against S.aureus by means of inhibition zones : ( 21 , 18 , 16 , 2 ) mm respectively . While its activity against E. coli at the concentrations above was : ( 17, 15, 10.3 , 0.0 ) mm rospectively . The cellular toxicity of the plant was determined and it Showed the toxicity towards Red Blood cell of Humam and Animal through the hemolysis Invitro .
