Description

Tangshenoside I is a bioactive saponin compound primarily extracted from the roots of *Codonopsis pilosula* (Dangshen). This high-purity reference standard is critical for analytical research and quality control in the herbal medicine and nutraceutical industries. It serves as a key marker compound for the authentication and standardization of *Codonopsis*-based products, ensuring efficacy and batch-to-batch consistency for manufacturers and research institutions globally.

Application

• Pharmaceutical Reference Standard: Used as a certified reference material (CRM) for the quantitative analysis and quality control of herbal drugs and finished formulations containing *Codonopsis pilosula*.
• Nutraceutical & Dietary Supplement Standardization: Acts as a primary bioactive marker for standardizing extracts used in immune-support and energy-boosting supplements to guarantee potency.
• Biomedical Research: Employed in pharmacological studies to investigate its potential effects on the immune system, gastrointestinal function, and anti-fatigue properties.
• Herbal Medicine Authentication: Essential for HPLC and LC-MS methods to authenticate Dangshen raw materials and detect adulteration in the supply chain.
• Cosmeceutical Ingredient Analysis: Used in the quality assessment of skincare products that utilize *Codonopsis* extract for its purported antioxidant and revitalizing benefits.
