The cells that were specialized and differentiated with the addition of precursors can produce more secondary metabolites than the in vivo cultures . It has been also used for treating fever, malaria, menstrual cycle regulation, as a euphoric drug , as tranquilizer, and for its ability to reduce arterial blood pressure .
Vinca alkaloids are now ve synthetically and used as drugs in cancer therapy and as immunosuppressive drugs.
Conozca las plantas medicinales. Eburnamine derivatives and the brain. Although, the vinca alkaloids are quite similar from a structural position, their toxicologic profiles are different extensively.
Anti-helminthic activity The infections produced by helminths are chronic diseases affecting human beings. Regulation of the terpene moiety biosynthesis of Catharanthus roseus terpene indole alkaloids.
Minor vinca alkaloids include minovincine, methoxyminovincine, minovincinine, vincadifformine, desoxyvincaminol, and vincamajine.
The detection is carried out using a fixed wave UV detector or a fluorescent detector. Biotechnology in Agriculture and Forestry Plant Tissue Cult Biotechnol. Certain chemical constituents are vinblastine, vindoline, catharantine, ajmalicine and serpentine ; the species are also rich in bisindole alkaloids approximately 40 compoundsmany of which contain a molecule of vindoline or catharantine . These drugs should not be used by a patient who is pregnant, has planning for pregnancy or has breast-feeding as it may cause birth defects.
The maximum concentration of vincristine 0. Furthermore, a considerable number of enzymes have been characterized and their respective cloned genes defined, with the production of the alkaloids been found as highly regulated at the transcriptional level.
Additionally, alkaloids have viinca detected in the pollen of C. Patients should not receive any vaccinations while taking this medication. Different percentages alvaloides crude methanol extracts of Catharanthus have shown anti-cancer activity against many types of cells under in vitro conditions  and a greater activity is especially found against multi-drug resistant tumors .

Vincristine regulates the phosphorylation of the antiapoptotic protein HSP27 in breast cancer cells. The influence of tryptophan on growth and catharanthine content in C. Furthermore, it shows high anti-plasmodial activity in vitro because of the presence of terpenoids, flavonoids and sesquiterpenes .
Antimicrobial activity of Catharanthus roseus – A detailed study. For example, the inclusion of pectinase increases alvaloides. The combination of different basal media as carbon sources, phytohormones and inducers of the biotic and abiotic type may provide useful ways for the rational technical development and the increase in production yields of several of these bioactive molecules in vitro.
