Influence of Some Heavy Metals on Growth, Alkaloid Content and Composition in Catharanthus roseus L.
Shoot biomass production, alkaloid content and composition as influence by cadmium, manganese, nickel and lead at uniform dose of 5 mM were investigated in Catharanthus roseus plants grown in sand culture. Treatment with Mn, Ni, and Pb significantly enhanced total root alkaloid accumulation. Cd and Ni treatment resulted in two-fold where as Pb treatment resulted in three fold increase in serpen...
متن کاملImproved alkaloid content in callus culture of Catharanthus roseus
The low yield and high market price of the pharmaceutically important alkaloids of Catharanthus roseus (L.) G. Don viz. vincristine, vinblastine and ajmalicine have created interest in improved alternative routes for their production such as using cell and tissue culture. The callus developed on Murashige and Skoog (MS) media supplemented with different concentrations of auxins and cytokinins w...

15 صفحه اولEFFECTS OF DROUGHT STRESS ON THE ALKALOID CONTENTS AND GROWTH PARAMETERS OF Catharanthus roseus
In the present investigation Catharanthus roseus, an important herb used in traditional as well as modern medicine, exposed to water deficit stress and possible changes in chlorophyll contents, photosynthesis rate, transpiration rate, growth parameters as well as total alkaloid content and vincristine and vinblastine levels were studied. Seedlings subjected to 4 different water-regimes. Experim...
متن کاملCryopreservation of Alkaloid-Producing Cell Cultures of Periwinkle (Catharanthus roseus).
A procedure for cryogenic storage of alkaloid producing cell lines of periwinkle, Catharanthus roseus (L.) G. Don., has been developed. The procedure differs from established cryopreservation protocols in several aspects. Specifically, 4-day-old suspension subcultures of three cell lines were precultured in nutrient media supplemented with 1 molar sorbitol for 6 to 20 hours. The cells were then...
