330DETERMINATION OF PRELIMINARY PHYTOCONSTITUENTS, TOTAL PHENOLIC AND FLAVONOIDS CONTENTS IN THE ROOTS, LEAVES AND STEMS OF CLEOME VISCOSA LINNCleome viscosa Linn, belongs to family Capparidaceae, it is widely distributed sultry herb with yellow flowers and long slender pods containing seeds. It is widely distributed throughout the tropics of world and has been used as medicinal herb due to its various biological activities like stomachic, laxative, diuretic, anthelmintic, skin diseases: itching, leprosy. In the present study, three different parts: roots, stems, and leaves of C. viscosa were extracted with Pet. ether , Chloroform, methanol, and water and all these extracts were screened for the presence of various plant metabolites (primary and secondary) including proteins, alkaloids, steroids, flavonoids, carbohydrates, and tannins. Further, these primary metabolites were quantitatively estimated, the results showed that maximum amount of soluble sugars and starch was found in the root and the alkaloid are absent in all three plant parts. Total flavonoid and phenolic contents were also determined in all three parts of C. viscosa, the results showed that.lalitkumar170@gmail.comResearch4122013Flavonoid,Phytoconstituents,Methanol extractLalit Kumar Bainiwal,Pratima Vijayvergia,Rekha VijayvergiaPlant Pathology and Biochemistry Laboratory, Department of Botany, University of Rajasthan, Jaipur-302004, India.,Plant Pathology and Biochemistry Laboratory, Department of Botany, University of Rajasthan, Jaipur-302004, India.,Plant Pathology and Biochemistry Laboratory, Department of Botany, University of Rajasthan, Jaipur-302004, India.
