Description

Hydroxysafflor Yellow A is a high-purity, bioactive flavonoid compound extracted from the safflower plant (*Carthamus tinctorius* L.). This compound is a key marker and active ingredient valued for its significant pharmacological properties, making it a critical standard and raw material for advanced research and product development. It is primarily sought by manufacturers and researchers in the pharmaceutical, nutraceutical, and cosmetic industries for its well-documented bioactivity.

Application

• Pharmaceutical Reference Standard: Used as a certified reference material (CRM) for the quality control and standardization of safflower-based herbal medicines and extracts.
• Active Pharmaceutical Ingredient (API) Intermediate: Serves as a key starting material or intermediate in the synthesis of cardiovascular and cerebrovascular protective drugs.
• Nutraceutical Formulation: Incorporated into dietary supplements for its antioxidant and anti-inflammatory benefits, supporting cardiovascular health.
• Cosmetic & Skincare Actives: Used in advanced cosmetic formulations for its skin-brightening and anti-aging properties, helping to improve skin tone and texture.
• Biomedical Research: Essential for in-vitro and in-vivo studies investigating mechanisms related to neuroprotection, anti-thrombosis, and anti-oxidation.
• Traditional Chinese Medicine (TCM) Modernization: A critical component in the development of standardized, quantifiable TCM products derived from safflower (Hong Hua).
