Description

Salvianolic Acid K is a bioactive phenolic acid compound derived from the traditional medicinal herb *Salvia miltiorrhiza* (Danshen). This high-purity standard is critical for research and development in the pharmaceutical and nutraceutical sectors, where precise chemical identity and activity are paramount. It serves as a key reference material for analytical laboratories, quality control departments, and formulation scientists working on cardiovascular, anti-inflammatory, and antioxidant applications.

Application

• Pharmaceutical Reference Standard: Used as a certified reference material (CRM) for the identification, assay, and impurity profiling of Danshen extracts and related pharmaceutical preparations.
• Biomedical Research: Employed in *in vitro* and *in vivo* studies to investigate mechanisms related to cardiovascular protection, neuroprotection, and anti-inflammatory pathways.
• Nutraceutical & Dietary Supplement Formulation: Incorporated as a standardized active ingredient in high-end supplements targeting circulatory health and antioxidant support.
• Quality Control & Analytical Testing: Serves as a primary standard for HPLC, LC-MS, and other chromatographic methods to ensure the quality and consistency of raw botanical materials and finished products.
• Cosmeceutical Development: Explored for its antioxidant properties in skincare formulations aimed at reducing oxidative stress and supporting skin health.
