Mutation breeding in Catharanthus roseus (L.) G. Don: An Overview
Induced mutagenesis is best approach for creation of genetic variability but most of interest is paid towards crop plants with only a few exceptions. But even widely used medicinal plants could receive a little attention in this direction. Catharanthus roseus is an important plant medicinal plant yielding antihypertensive alkaloid ajmalcine and anticancerous alkaloid vincristine and vinblastine...
متن کاملAction of aqueous extracts of Phyllanthus niruri L. (Euphorbiaceae) leaves on meristematic root cells of Allium cepa L.
This study aimed to evaluate the effects of aqueous extracts of dried Phyllanthus niruri L. (stonebreaker) leaves on Allium cepa L. root meristem cells at four concentrations, 0.02 (usual concentration), 0.04, 0.06 and 0.08mg/mL and exposure times of 24 and 48 hours. For each concentration we used a group of five onion bulbs that were first embedded in distilled water and then transferred to th...
متن کاملFreezing Characteristics of Cultured Catharanthus roseus (L). G. Don Cells Treated with Dimethylsulfoxide and Sorbitol in Relation to Cryopreservation.
The freezing behavior of dimethylsulfoxide (DMSO) and sorbitol solutions and periwinkle (Catharanthus roseus) cells treated with DMSO and sorbitol alone and in combination was examined by nuclear magnetic resonance and differential thermal analysis. Incorporation of DMSO or sorbitol into the liquid growth medium had a significant effect in the temperature range for initiation to completion of i...
متن کاملAntidiabetic and antioxidant properties of alkaloids from Catharanthus roseus (L.) G. Don.
Catharanthus roseus (L.) G. Don is a herbal plant traditionally used by local populations in India, South Africa, China and Malaysia to treat diabetes. The present study reports the in vitro antioxidant and antidiabetic activities of the major alkaloids isolated from Catharanthus roseus (L.) G. Don leaves extract. Four alkaloids--vindoline I, vindolidine II, vindolicine III and vindolinine IV--...
متن کاملProduction and characterization of arabinogalactan protein (AGP) from a hairy root line of Catharanthus roseus (L.) G. Don
Arabinogalactan protein (AGP), a class of cell wall proteoglycan, was isolated from the hairy root cultures of a newly developed hairy root line IIT-BT/D1 of Catharanthus roseus (L.) G. Don. AGP was found to be present both in the roots (0.3 mg/g fresh weight) and in the spent media (47 mg/L). The compositional analysis revealed the predominance of arabinose and galactose sugar, a characteristi...
