Updated: 2026-08-04

Overview

Sophora extract is derived from the roots of Sophora flavescens, a plant native to East Asia. It has been used in traditional Chinese medicine for centuries due to its therapeutic properties. The extract is rich in alkaloids such as matrine and oxymatrine, which contribute to its pharmacological effects. Modern applications extend beyond medicine to include cosmetics and agricultural products, where it serves as a natural alternative to synthetic chemicals. In the pharmaceutical industry, Sophora extract is valued for its anti-inflammatory and antimicrobial properties. It is commonly used in treatments for skin conditions, digestive disorders, and respiratory infections. The cosmetic industry utilizes it for its soothing and antimicrobial effects, making it a popular ingredient in skincare products. In agriculture, it acts as a natural pesticide, offering an eco-friendly solution for pest control.

Sophora extract typically appears as a yellowish-brown powder or liquid, depending on the extraction process. It is soluble in water and ethanol, making it versatile for various formulations. The extract's density ranges from 1.1 to 1.2 g/cm³ for liquid forms, though this can vary based on concentration and solvent used. The bioactive compounds in Sophora extract, particularly matrine and oxymatrine, are responsible for its key properties. These alkaloids exhibit strong antimicrobial activity against a wide range of pathogens. The extract also demonstrates anti-inflammatory effects, which are beneficial in medical and cosmetic applications. Its stability under normal storage conditions ensures a long shelf life, provided it is kept in a cool, dry environment.

While Sophora extract is generally safe for use, it can cause skin irritation in sensitive individuals. Proper handling, including the use of gloves and protective clothing, is recommended during formulation and application. Ingestion of large quantities may lead to gastrointestinal discomfort, so dosage control is crucial in pharmaceutical and cosmetic products. Storage conditions play a significant role in maintaining the extract's efficacy. It should be kept in a cool, dry place, away from direct sunlight and moisture. Liquid forms may require refrigeration to prolong shelf life. Manufacturers should provide clear labeling and safety data sheets (SDS) to ensure proper handling and storage by end-users.
