[Quality control of semen Cassiae]
Summary
A new HPLC method accurately quantifies chrysophanol in Semen Cassiae. This method ensures reliable analysis of chrysophanol content in medicinal plant samples.
Area of Science:
- Pharmacognosy
- Analytical Chemistry
Context:
- Semen Cassiae is a traditional Chinese medicine.
- Chrysophanol is a key active compound in Semen Cassiae.
Purpose:
- To develop and validate a reversed-phase High-Performance Liquid Chromatography (HPLC) method for determining chrysophanol in Semen Cassiae.
Summary:
- A reversed-phase HPLC method was established for chrysophanol determination.
- Extraction conditions for free and combined chrysophanols were optimized.
- The method demonstrated high average recoveries (101.2% and 103.3%) and low relative standard deviations (RSDs) (3.5% and 1.8%) for 14 samples.
Impact:
- Provides a reliable analytical method for quality control of Semen Cassiae.
- Facilitates research on chrysophanol's pharmacological activities and applications.
