Description

Calycosin is a bioactive isoflavone compound, a key marker constituent derived from the roots of *Astragalus membranaceus* (Huangqi). This high-purity phytochemical is valued for its significant role in research and development within the life sciences sector. It serves as a critical reference standard and active ingredient for manufacturers in the nutraceutical, pharmaceutical, and cosmetic industries. Its consistent quality and reliable supply are essential for ensuring the efficacy and standardization of final products.

Application

• Pharmaceutical Reference Standard: Used as a certified reference material (CRM) for the quality control and standardization of herbal extracts and finished pharmaceutical products.
• Nutraceutical Formulations: Incorporated into dietary supplements and functional foods for its researched bioactive properties, supporting immune and cardiovascular health.
• Biomedical Research: Serves as a crucial tool in pharmacological and biochemical studies investigating mechanisms of action, pharmacokinetics, and bioactivity.
• Cosmeceutical Ingredients: Utilized in advanced skincare products for its potential antioxidant and anti-aging benefits.
• Herbal Extract Standardization: Acts as a quantitative marker to ensure the potency, consistency, and authenticity of *Astragalus* and related botanical extracts.

Quality Control

Our Calycosin is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity verification and identity confirmation by spectroscopic methods (IR, UV, MS). We provide Certificates of Analysis (COA) with detailed specifications to ensure compliance with research and cGMP-grade requirements for reference standards and active ingredients.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its light-sensitive nature and propensity to be easily oxidized (store under inert atmosphere), prolonged exposure to air and light should be avoided. For long-term storage under an inert atmosphere such as argon or nitrogen, please contact us.
