Description

Capillarisin is a bioactive flavonoid compound isolated from the traditional medicinal herb *Artemisia capillaris*. This high-purity reference standard is essential for research and development in the pharmaceutical and nutraceutical sectors, where precise chemical characterization is critical. It is primarily sought after by scientists and quality control professionals for its role in analytical method development, phytochemical research, and the standardization of herbal extracts.

Application

• Pharmaceutical Reference Standard: Used as a certified reference material (CRM) for the identification, assay, and purity testing of herbal medicines and related products.
• Bioactivity and Pharmacological Research: Serves as a key compound in studies investigating hepatoprotective, anti-inflammatory, choleretic, and antioxidant effects.
• Herbal Extract Standardization: Acts as a marker compound for the quality control and batch-to-batch consistency of *Artemisia capillaris* (Yin Chen) extracts in TCM and dietary supplements.
• Analytical Method Development: Employed in developing and validating HPLC, UPLC, and LC-MS/MS methods for flavonoid analysis.
• Academic and Institutional Research: Used in universities and research institutes for chemical, biological, and metabolic pathway studies.
• Cosmeceutical Ingredient Research: Investigated for potential applications in skincare formulations due to its antioxidant properties.
