Description

o-Acetylschisantherin L is a bioactive lignan derivative, a key marker compound for the quality control of *Schisandra* species. This high-purity reference standard is critical for ensuring the efficacy, safety, and batch-to-batch consistency of botanical extracts and finished products. It is primarily required by analytical laboratories, nutraceutical manufacturers, and pharmaceutical R&D teams focused on natural product development and standardization.

Application

• Pharmaceutical Reference Standard: Used as a certified reference material (CRM) for the quantitative and qualitative analysis of Schisandra chinensis extracts in drug development and quality control.
• Nutraceutical Standardization: Serves as a primary marker for standardizing herbal dietary supplements to ensure consistent potency and meet label claims.
• Pharmacological Research: Employed in in vitro and in vivo studies to investigate its hepatoprotective, anti-inflammatory, and neuroprotective biological activities.
• Analytical Method Development: Essential for developing and validating HPLC, UPLC, and LC-MS/MS methods for the identification and assay of schisantherin compounds.
• Botanical Extract Authentication: Acts as a key identifier to authenticate Schisandra raw materials and detect adulteration in the supply chain.
• Cosmeceutical Ingredient Analysis: Used to quantify active constituents in cosmetic formulations claiming antioxidant benefits from Schisandra extracts.
