The objective was to develop a High-Performance Liquid Chromatography (HPLC) method to analyze two specific compounds in the bark of Paeonia Suffuticosa.
The method used a reversed-phase HPLC system with a specific column and mobile phase, operating at a flow rate of 0.8 mL/min and UV detection at 274 nm.
Results showed strong linearity for both compounds tested and high average recovery rates, indicating the method is effective, simple, and suitable for assessing the quality of the bark.
