Allelopathic Potentials of Medicinal Plant, Vinca rosea L.
Allelopathy offers potential for weed control through the production and release of allelochemicals from leaves, flowers, seeds, stems and roots. In this research, allelopathy potentials of ethanolic and aqueous extracts of Vinca rosea L. leaves were evaluated. Three extract concentrations, including 2.5, 5 and 10% (w/v) of both aqueous and ethanolic were prepared from a 10% w/v stock solution...
متن کاملVinca Alkaloids
Vinca alkaloids are a subset of drugs obtained from the Madagascar periwinkle plant. They are naturally extracted from the pink periwinkle plant, Catharanthus roseus G. Don and have a hypoglycemic as well as cytotoxic effects. They have been used to treat diabetes, high blood pressure and have been used as disinfectants. The vinca alkaloids are also important for being cancer fighters. There ar...
متن کاملThe Role of the Alkaloids of Catharanthus Roseus (l.) G.don (vinca Rosea) and Their Derivatives in Cancer Chemotherapy
The search for useful foodstuffs, dyes, medicinal agents, and other materials from plants, animals, or minerals is as old as civilization itself. It should not be surprising, therefore, to learn that all pharmacological prototypes originate from one of these three kingdoms. The alkaloids, nitrogen-containing plant bases, notwithstanding the advent of antibiotics and many valuable synthetic drug...
متن کاملGlucosyl Zeatin and Glucosyl Ribosylzeatin from Vinca rosea L. Crown Gall Tumor Tissue.
Recently detected but unidentified cytokinin activity in crown gall tumor tissue from Vinca rosea L. grown on media containing sources of reduced nitrogen has now been attributed to two adenine-type cytokinins. These compounds are glucopyranosyl derivatives of zeatin and ribosylzeatin. The substitution in each case is on the isopentenyl chain of the parent compound. Neither of these compounds h...
متن کاملRevised Methods for Purification of Ribosyl-trans-zeatin from Vinca rosea L. Crown Gall Tumor Tissue.
Ribosyl-trans-zeatin has been purified from Vinca rosea L. crown gall tumor tissue by using two new sequences of isolation procedures. Identification of the compound has been established by mass spectrometry, ultraviolet absorbancy spectra, chromatographic values, and growth activity. The isolation sequences eliminate the exposures to pH extremes and the strong cation-exchange resin used in the...
