Chemical studies of launaea nudicaulis hook f. Extracts with antioxidant and urease inhibitory activities

An activity guide isolation of launaea nudicaulis hook f,medicinal plant of indo-pak region has shown antioxidant potentials via its polar solvent soluble fractions while urease inhibition studies (in vitro) indicated compound 8 and 9 as a good urease inhibitors. eight compounds have also been isolated for the first time from launaea nudicaulis hook f.,namely,scopoletin 1,lupeol 2,β-amyrin 3,β-sitosterol 3-o-β-d-glucopyranoside 4,stigmasterol 3-o-β-d-glucopyranoside 5,6- hydroxy flavone 6,7-methoxy flavone 7 and kaempferol 8,respectively. their structures were elucidated by ei-ms,fabms,1h-nmr spectroscopic data.
