Description

Gomisin U is a bioactive lignan compound isolated from the fruit of *Schisandra chinensis*. This high-purity reference standard is critical for research and development in the pharmaceutical and nutraceutical sectors, where precise chemical characterization is paramount. It serves as a key analytical standard for quality control in the production of botanical extracts and as a vital tool for pharmacological studies targeting liver health and metabolic functions.

Application

• Pharmaceutical Reference Standard: Used as a certified reference material (CRM) for the identification, assay, and purity testing of Schisandra chinensis extracts and finished products.
• Nutraceutical & Dietary Supplement Formulation: Employed in the standardization of botanical supplements to ensure consistent potency and efficacy.
• Pharmacological Research: A vital tool for in vitro and in vivo studies investigating hepatoprotective, anti-inflammatory, and anti-cancer properties.
• Analytical Chemistry: Serves as a critical standard for method development and validation in HPLC, LC-MS, and other chromatographic analyses.
• Academic & Institutional Research: Used in universities and research institutes for studying the biochemistry and mechanisms of action of lignan compounds.
