Description

Puerarin is a major bioactive isoflavone-C-glucoside primarily extracted from the root of the kudzu vine (*Pueraria lobata*). This high-purity compound is valued for its significant role in research and development across the pharmaceutical and nutraceutical industries. It serves as a critical reference standard and active ingredient for applications targeting cardiovascular health, neuroprotection, and metabolic regulation. Global suppliers in the life sciences sector rely on consistent, high-quality Puerarin CAS NO 3681-99-0 for product formulation and advanced clinical studies.

Application

• Pharmaceutical Intermediate: Used in the research and development of cardiovascular drugs, neuroprotective agents, and treatments for diabetes and osteoporosis.
• Dietary Supplement & Nutraceutical Formulation: Incorporated into capsules, tablets, and powders for its antioxidant and anti-inflammatory properties.
• Reference Standard: Serves as a certified standard for quality control and analytical testing (HPLC, LC-MS) in laboratories.
• Cosmeceutical Research: Investigated for its potential in anti-aging and skin-brightening topical formulations.
• Academic & Clinical Research: Employed in biochemical, pharmacological, and pharmacokinetic studies to elucidate mechanisms of action.
• Traditional Medicine Modernization: Used as a marker compound in the standardization of herbal extracts derived from kudzu root.

Quality Control

Our Puerarin is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, identity confirmation by IR and UV, and residual solvent analysis, to ensure it meets stringent specifications for research and production use. Certificates of Analysis (COA) detailing all test results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture.
