1. Product Description & Key ParametersSchisandra Chinensis Extract (Wuweizi Extract) is a natural botanical extract derived from the dried ripe fruits of Schisandra chinensis (Turcz.) Baill., a deciduous woody vine belonging to the Schisandraceae family, commonly known as "Wuweizi" in traditional Chinese medicine. It has a long history of application in traditional Chinese medicine for its effects of astringing the lung and stopping cough, tonifying the kidney and securing essence, nourishing the heart and calming the mind, and protecting the liver. The extract is produced through advanced water-ethanol mixed solvent extraction (ratio 58:42 v/v), purification, concentration and spray-drying processes, which effectively retain the plant's bioactive components. The final product is a reddish-brown to dark brown fine powder with a characteristic sour-sweet herbal odor, good flowability and no visible impurities, consistent with the typical appearance of Schisandra chinensis extract.

The product complies with international standards of food grade, cosmetic grade and pharmaceutical grade, ensuring high quality, safety and reliability for wide application in multiple fields. It also contains characteristic dibenzocyclooctadiene lignans of Schisandra chinensis, which are the main material basis for its traditional medicinal effects and modern biological activities.2. Features - Natural and High-Quality Sourcing: Sourced from high-quality Schisandra chinensis grown in pollution-free areas (main producing areas: Liaoning, Jilin, Heilongjiang of China), the raw materials are strictly selected-plump, uniform dried ripe fruits are cleaned, dried and processed to ensure no impurities. No artificial colors, flavors or preservatives are added during the extraction process, making it a safe and natural botanical ingredient with a long history of traditional application. The raw materials are grown in cool and humid mountainous areas, ensuring the natural active components of the fruits are fully retained.
- Standardized Parameters and High Purity: Strictly controlled parameters (active ingredient content, particle size, solubility, etc.) ensure batch consistency. Precise extraction and purification technologies concentrate core active ingredients such as schisandrin and total lignans, with high-purity specifications reaching HPLC ≥98%, resulting in high bioavailability that better exerts its functional effects, especially in liver protection and antioxidant activities. The content of active ingredients can be accurately determined by HPLC method, ensuring product quality stability.
