Description

Ophiopogonin A CAS NO 11054-24-3 is a bioactive steroidal saponin primarily extracted from the tuberous roots of *Ophiopogon japonicus* (Maidong). This high-purity reference standard is critical for analytical research and quality control in the pharmaceutical and nutraceutical industries. It is essential for researchers and manufacturers developing and standardizing herbal medicines, functional foods, and novel therapeutic agents.

Application

• Pharmaceutical Reference Standard: Used as a certified reference material (CRM) for the identification, assay, and impurity profiling of Ophiopogon extracts and related formulations in pharmacopoeial testing.
• Bioactivity and Pharmacological Research: Serves as a key compound in studies investigating anti-inflammatory, cardioprotective, anti-angiogenic, and anti-cancer mechanisms.
• Herbal Medicine Quality Control: Acts as a marker compound for the standardization and authentication of *Ophiopogon japonicus* raw materials and finished products (e.g., Mai Men Dong Tang).
• Nutraceutical and Functional Food Development: Employed in the formulation and quality assurance of dietary supplements targeting cardiovascular and metabolic health.
• Academic and Institutional Research: Used in universities and research institutes for structural elucidation, metabolic pathway studies, and synthesis of derivatives.
