Natural 100%Pure Bulk Periwinkle Extract Vinca Minor Extract with High Quality
Product Description
Introduction:
Periwinkle extract is derived from Catharanthus roseus (formerly Vinca rosea), a flowering plant with a dual identity in both traditional medicine and modern pharmacology. This complex extract contains over 130 characterized alkaloids, most notably vinblastine and vincristine - two compounds that revolutionized cancer chemotherapy. The extract's phytochemical profile varies significantly between leaf, root, and flower sources, with leaf-derived extracts containing the highest concentration of bioactive vinca alkaloids. While the whole plant has been used in Ayurvedic medicine for diabetes management, modern applications focus on its cytotoxic alkaloids which interfere with microtubule formation in rapidly dividing cells. The extract's bitter taste and light-to-dark brown coloration reflect its complex mixture of indole and dihydroindole alkaloids, flavonoids, and phenolic compounds. Current research explores standardized extracts with optimized alkaloid ratios to balance efficacy and safety profiles.

Applications of Periwinkle Extract
Periwinkle extract serves critical roles in both pharmaceutical and nutraceutical applications. In oncology, isolated vinca alkaloids form the basis of chemotherapeutic regimens for lymphomas, leukemias, and solid tumors, with vinblastine particularly effective against Hodgkin's disease and vincristine essential for pediatric ALL protocols. The extract's hypoglycemic properties, attributed to alkaloids like leurosine, support its use in diabetic supplements targeting glucose metabolism. Neurological applications are emerging for vincamine-rich extracts, which demonstrate cerebrovascular dilating effects potentially beneficial for cognitive function and age-related memory decline. The extract's antimicrobial activity against drug-resistant pathogens has spurred research into topical formulations for wound care. In controlled doses, specific alkaloid fractions show promise for autoimmune condition management through immunomodulatory mechanisms. Recent advances in plant tissue culture allow for sustainable production of target alkaloids without wild harvesting. Quality standardization is particularly crucial, with HPLC analysis required to verify alkaloid concentrations and ratios - typically 0.2-1% total vinca alkaloids for therapeutic extracts. Emerging biotechnological approaches focus on elicitation techniques to enhance production of specific alkaloids while reducing unwanted compounds. The extract's multifaceted bioactivity continues to inspire research into novel applications, including anti-angiogenic therapies and microtubule-stabilizing approaches for neurodegenerative diseases.
