ABSTRACT
Medicinal plants are the most potential resource of new therapeutic agents. They are diverse, largely productive, biologically active and chemically unique; among their constituents [polyphenol compounds group] one of the main determinant factors in evaluating the pharmacological potentials i.e. polyphenols display an array of pharmacological properties such as antioxidant, immunostimulant, antitumor and antiparasitic effects. Cancer is a dreadful human disease, increasing with changing life style, nutrition and global warming while current available anticancer drugs cause serious side effects in most instances. Several reports suggested the relationship between antioxidant, anticancer and antiparasitic effects; they suggested that they act indirectly through promoting host resistance, restabilizing body equilibrium and conditioning body tissues in addition to their direct effect on certain parasites involved in cancer etiology. This work was conducted for estimation of total phenolic, flavonoids, phenylethanoid glycoside and iridoid content of twenty-three selected Egyptian plants as well as screening of their anticancer, antioxidant and antileishmanial effects, the overall gained results for suggest that the most suitable medicinal plant used as anticancer and antioxidant is Petrea volubilis L. which contain adequate mixture of total phenolic compounds 88.7 mg% and flavonoids 50.80 mg% and also suggest that flavonoid compounds are the category of phenolic compounds possess significant antioxidant and anticancer effects while the antilieshamnia screening revealed that Thymus decussatus Benth. extract exhibited the highest effect due to the presence of flavonoids and iridoids in adequate combination where iridoid compounds 201 mg% and flavonoid content was 128 mg%
