Description

Calycosin 7-o-Glucoside is a bioactive flavonoid glycoside, a key marker compound derived from the roots of *Astragalus membranaceus* (Huangqi). This high-purity reference standard is essential for ensuring the quality, consistency, and efficacy of herbal extracts and finished products. It is primarily utilized by manufacturers and researchers in the pharmaceutical, nutraceutical, and cosmeceutical industries for analytical, research, and development purposes.

Application

• Pharmaceutical Reference Standard: Used as a primary chemical reference marker for the quality control and standardization of *Astragalus*-based herbal medicines and extracts.
• Nutraceutical Ingredient: Incorporated into dietary supplements targeting immune support, anti-aging, and cardiovascular health, leveraging its bioactive properties.
• Biomedical Research: Serves as a critical tool in pharmacological studies investigating anti-inflammatory, antioxidant, anti-diabetic, and neuroprotective mechanisms.
• Cosmeceutical Formulations: Applied in advanced skincare products for its potential anti-aging and skin-rejuvenating effects.
• Analytical Chemistry: Employed as a calibration standard in HPLC, LC-MS, and TLC methods for quantitative and qualitative analysis.
• Traditional Chinese Medicine (TCM) Modernization: Supports the scientific validation and standardization of TCM formulas containing Huangqi.
