Description

p-Coumaroylastragalin is a specialized flavonoid glycoside compound, a key marker and active constituent found in various 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 phytochemical industries who require precise, reliable materials for method validation, bioactivity studies, and product formulation.

Application

• Pharmaceutical Reference Standard: Used as a certified reference material (CRM) for the identification, assay, and purity testing of herbal drugs and preparations in pharmacopeial methods.
• Bioactivity & Pharmacological Research: Employed in in vitro and in vivo studies to investigate potential anti-inflammatory, antioxidant, and metabolic regulatory properties.
• Nutraceutical & Dietary Supplement Quality Control: Acts as a quantitative marker for standardizing botanical extracts (e.g., from Astragalus species) to ensure consistent potency and efficacy in finished products.
• Analytical Method Development: Essential for developing and validating HPLC, UPLC, and LC-MS/MS methods in analytical laboratories for natural product analysis.
• Academic Research & Teaching: Used in university and institutional labs for phytochemical isolation, structural elucidation, and metabolic pathway studies.

Quality Control

Our p-Coumaroylastragalin is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing including HPLC for purity, NMR and MS for structural confirmation, and residual solvent analysis. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting the exact specifications and test results. We support compliance with ISO, GMP, and relevant pharmacopeial guidelines for reference standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C. This product is hygroscopic (moisture-sensitive) and should be handled in a low-humidity environment. For long-term storage, consider desiccation. Keep container tightly sealed when not in use.
