Catharanthus roseus (L.) which is an important medicinal plant of the family Apocynaceae is used to treat many of the fatal diseases contains a virtual cornucopia of useful alkaloids, used in diabetes, blood pressure, asthma, constipation, and cancer and menetrual problem. There are about two common cultivars of C. roseus which is named on the basis of their flower colour that is the pink flowe...

In the present study aqueous extract of Piper nigrum seeds and Vinca rosea flowers were administered orally to alloxan induced diabetic rats once a day for 4 weeks. These treatments lead to significant lowering of blood sugar level and reduction in serum lipids. The levels of antioxidant enzymes, catalase and glutathione peroxidase decreased in alloxan induced diabetic rats however these levels...

Catharanthus roseus (= Vinca rosea), Adenine Phosphori­ bosyltransferase, Subcellular D istribution, Mitochondria, Purine Salvage Subcellular localization of adenine phosphoribosyltrans­ ferase was examined in Catharanthus roseus cells. At least 13% of the activity was observed in the particulate fraction with the rest observed in the cytosol. Both differential and Percoll density gradient cent...

Oral administration of water fraction of alcoholic extract of leaves of Vinca rosea (fam. apocynaeceae) led to marked lowering of blood glucose level in normal and streptozotocin induced diabetic rats. The hypoglycemic effect of the fraction was comparable with that of tolbutamide.

Catharanthus roseus is a medicinal herb found in many tropical and subtropical regions around the world. This plant produces a diverse array of secondary metabolites that are pharmaceutically important like vinblastine and vincristine used as chemotherapeutic agents in the treatment of several types of cancers. Low yield of these vinca alkaloids from the plant in vivo and the challenges to meet...

Medicinal herbs are significant source of synthetic and herbal drugs. Before the availability of synthetic drugs, man was completely dependent on herbs as healthcare system. Medicinal herbs have been on the forefront whenever we talk about anticancer remedies. Vinca rosea (sadabahar) alkaloids, Vinblastine and Vincristine, are the most potent anticancer drugs known. Taxol isolated from Taxus br...
