Schisandrin

Schisandrin (CAS 7432-28-2), also known as Schizandrol A, is the primary bioactive lignan extracted from the dried fruit of Schisandra chinensis. Wuweizichun A is the name used in Chinese pharmacopoeia contexts, making it a relevant search term for buyers sourcing to those specifications. It is used commercially as a reference standard, active ingredient, and botanical extract marker compound across pharmaceutical and nutraceutical supply chains. In dietary supplement formulation, it serves as the quantification marker for standardized extracts.

This allows manufacturers to verify potency and meet label claims. Pharmaceutical developers use isolated Schisandrin as an active pharmaceutical ingredient or research compound in hepatoprotective and adaptogenic product development. As a reference standard, it supports QC laboratories performing HPLC-based identity and purity testing of raw botanical materials. In functional food and beverage applications, standardized extracts are used to deliver antioxidant activity.

Schisandrin is supplied as a white to off-white crystalline powder in quantities ranging from analytical-scale milligrams to bulk kilogram lots. It is available in reference standard grade with purity levels of HPLC 98 percent or higher. The material is also available as a component of standardized botanical extracts. Specifications commonly align with Chinese Pharmacopoeia and USP botanical monograph requirements to ensure consistent quality and safety.
