Description

p-Coumaroylastragalin is a specialized flavonoid glycoside compound, a key phytochemical constituent found in certain medicinal plants. This high-purity reference standard is critical for analytical research, quality control, and the development of standardized botanical extracts. It serves researchers and manufacturers in the pharmaceutical, nutraceutical, and cosmeceutical industries who require precise, reliable compounds for method validation and product development.

Application

• Pharmaceutical Reference Standard: Used as a certified reference material (CRM) for the identification, assay, and purity testing of herbal drug preparations and finished products.
• Bioactivity Research: Employed in in vitro and in vivo studies to investigate potential antioxidant, anti-inflammatory, and other pharmacological properties.
• Nutraceutical Standardization: Acts as a marker compound for the quality control and standardization of dietary supplements derived from astragalus or other related botanicals.
• Analytical Method Development: Essential for developing and validating HPLC, LC-MS, and other chromatographic methods for complex plant matrices.
• Cosmetic Ingredient Research: Utilized in R&D for skincare formulations exploring natural active ingredients with purported protective benefits.
