Description

Gomisin K1 is a bioactive lignan compound isolated from the fruit of *Schisandra chinensis*. This high-purity reference standard is critical for analytical research, quality control, and the development of nutraceutical and pharmaceutical products. It serves as an essential material for scientists and manufacturers in the phytochemical, natural product, and life science industries requiring precise identification and quantification.

Application

• Pharmaceutical Reference Standard: Used as a certified reference material (CRM) for the identification, assay, and impurity profiling of herbal extracts and finished products in HPLC and LC-MS analysis.
• Nutraceutical R&D: Serves as a key marker compound for the standardization and quality assurance of Schisandra chinensis (Wu Wei Zi) extracts in dietary supplement formulations.
• Biological Activity Research: Employed in in vitro and in vivo studies to investigate its potential pharmacological properties, including hepatoprotective, anti-inflammatory, and antioxidant effects.
• Cosmetic Ingredient Analysis: Utilized in the quality control of natural cosmetic ingredients where Schisandra extract is valued for its skin-beneficial properties.
• Academic Research: Provides a pure compound for university and institutional research into lignan chemistry, biosynthesis, and metabolic pathways.
