Aphidicidal Activity of Different Aqueous Extracts of Bitter Apple Citrullus Colocynthis (l.) against the Bird Cherry-oat Aphid, Rhopalosiphum Padi (l.) (homoptera: Aphididae) under Laboratory Conditions
The impacts of aqueous extracts from different parts (root, stem, leaf and fruit) of bitter apple Citrullus colocynthis (Cucurbitales: Cucurbitaceae), with five different concentrations, on controlling the bird cherry-oat aphid, Rhopalosiphum padi (L.) (Homoptera: Aphididae) were investigated under laboratory conditions. Results showed that the effects of the aqueous extracts from different par...
متن کاملEvaluation of antioxidant activity of Citrullus colocynthis (L.) Schrad. extracts and their effect on urease activity
This study was aimed to evaluate the antioxidative and urease inhibitory properties of the extracts from Citrullus colocynthis L. The extracts of the root and pulp of fruit were prepared by soxhlet apparatus in methanol as solvent. The antioxidative activities, including DPPH radical scavenging activity, reducing power and total antioxidant activity were studied in vitro. The ...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولCucurbitacins from the Leaves of Citrullus colocynthis (L.) Schrad.
Two new tetracyclic cucurbitane-type triterpene glycosides were isolated from an ethyl acetate extract of Citrullus colocynthis leaves together with four known cucurbitacins. Their structures were established on the basis of their spectroscopic data (mainly NMR and mass spectrometry). Evaluation of the in vitro cytotoxic activity of the isolated compounds against two human colon cancer cell lin...
