Description

Picrosideⅱ is a bioactive iridoid glycoside compound isolated from plants of the genus *Picrorhiza*. This high-purity reference standard is essential for research and development in the pharmaceutical and nutraceutical sectors, providing a reliable benchmark for analytical and biological studies. It is primarily sought by professionals in pharmaceutical R&D, quality control laboratories, and academic institutions focusing on natural product chemistry and pharmacology.

Application

• Pharmaceutical Reference Standard: Used as a certified reference material (CRM) for the identification, assay, and purity testing of herbal extracts and finished products.
• Bioactivity Research: Serves as a key compound in pharmacological studies investigating hepatoprotective, neuroprotective, anti-inflammatory, and antioxidant activities.
• Analytical Method Development: Employed as a primary standard for developing and validating HPLC, UPLC, and LC-MS methods in quality control laboratories.
• Nutraceutical Standardization: Critical for standardizing herbal supplements and extracts derived from *Picrorhiza kurroa* to ensure consistent potency and efficacy.
• Academic Research: Used in university and institutional research for metabolic studies, pharmacokinetics, and structure-activity relationship (SAR) analysis.
