Introduction Catharanthus roseus ( Vinca ) also known as the Madagascar periwinkle or rosy periwinkle or Sadabahar is grown as an ornamental plant in the garden as well as used for medical purpose. The plant is a native of Madagascar but also found in Australia, South Africa and Asia. In India, it is mostly found in Tamil Nadu, Karnataka, Gujarat, Odisha, West Bengal and Andhra Pradesh. Kingdom: Plantae Division: Magnoliophyta Class: Magnoliopsida Order: Gentianales Family: Apocynaceae Genus: Catharanthus Species: C. roseus (http://www.visionlearning.com/)

Vincristine & Vinblastine Catharanthus roseus –Studied extensively for its remarkable anticancer constituents i.e.-Vincristine & Vinblastine. These two are very powerful anticancerous compounds of terpenoid indole alkaloids. The productivity of vinblastine and vincristine is very low in plants (0.001-0.0003%) resulting in their extraordinary high price.This poses a serious challenge to all including biotechnologists as to improve the yield and to reduce unit cost. Vincristine – C 46 H 56 N 4 O 10, more active,less stable,less used,used in acute leukemia especially in children.
Vincristine & Vinblastine Vinblastine- C 46 H 58 N 4 O 9 ,more used,used for Hodgkin's lymphoma, non-small cell lung cancer, bladder cancer, brain cancer, melanoma, and testicular cancer .
Extraction Method- 5 kg powdered plant of C. roseus was percolated with methanol (95 %, 10 L × 3) for 1 hour each. The methanolic extracts were filtered and concentrated at 50 °C in vacuo to 500 ml, diluted with water (200 ml), acidified with 1 N sulfuric acid (pH 2) and extracted with ethyl acetate (500 ml × 3). The EtOAc extract was discarded out. The aqueous solution was adjusted to pH 6.4 using NH 4 OH solution (25 %) and then extracted with methylene chloride (500 ml × 3). The combined methylene chloride extract was washed with water till free from acidity, dried over anhydrous sodium sulfate, filtered and evaporated to dryness under reduced pressure to give an alkaloidal fraction (F). www.mdpi.org/molecules(A Simplified Procedure for Indole Alkaloid Extraction from Catharanthus roseus )2007, Arvind Verma 1,2,*, Into Laakso 2,*, Tuulikki Seppänen-Laakso 3

Side effects Loss of white blood cells and blood platelets, Hair loss,high blood pressure gastrointestinal problems,depression,muscle cramps vertigo and headaches Vinblastine -Causes birth defects so not used for pregnants,Bonemarrow damage is a limiting factor Vincristine- Neurotoxicity is dose limiting factor causes damage to peripheral NS
Therapeutic properties/uses Anti diabetic property- The ethanolic extracts of the leaves and flower of C. roseus showed a dose dependent lowering of blood sugar in comparable to the standard drug gliben clamide . The Hypo glycemic effect has appeareddue to the result of the increase glucose utilization in the liver. Anti bacterial property- Crude extracts from different parts of the plant was tested for anti bacterial activity. Extract from leaves showed significantly higher efficacy. The anti bacterial activity of the leaf extract of the plant was checked against micro organism like Pseudomonasaeruginosa NCIM2036, Salmonella typhimuruim NCIM2501, Staphylococus aureus NCIM5021and was found that the extracts could be used as the prophylactic agent in the treatment of manyof the disease. Anti oxidant property- The anti oxidant potential of the ethanolic extract of the roots of the two varieties of C. roseus namely rosea (pink flower) and alba (white flower) was obtained. www.ijpab.com ( Catharanthus roseus (An anti-cancerous drug yielding plant) (2013),Author-Monika sain,Vandana sharma
Continued.. Anti helminthic property- Helminthes infections are the chronic illness, The ethanolic extract was found to show the significant anti helminthic activity. Anti ulcer property- Vincamine and Vindoline alkaloids of the plant showed anti ulcer property. Antihypertensive property- Extract of leaves of th plant made significant change in hypotensive. Anti diarrheal property-
Conclusion Catharanthus roseus has been investigated clinically as it is an important medicinal plant with immense anti cancerous potentiality. C.roseus is an amazing chemical factory,producing more than 130 TIAs,some of which exhibit strong pharmacological activities. The plant also possess various properties.Hence most work could be done on the above plant to reveal the unknown mysteries.
