Establishment and Evaluation of Determination of Cinnamaldehyde in Baoyuanqingxue Granules by HPLC

Abstract:

To examine the extraction method and chromatographic conditions that affect the determination of cinnamaldehyde in Baoyuanqingxue granules and make clinical evaluation about the determination of cinnamaldehyde.Ultrasonic methanol extraction was used before the detemination of cinnamaldehyde in Baoyuanqingxue granules. High Performance Liquid chromatography (HPLC) method was applied to detect samples. The SB-C18 column (Agilent, ZORBAX, 4.6×150mm, 5μm) was adopted, the mobile phase was acetonitrile-water (35:65) at the flow rate of 1.00mL•min-1 with DAD detection wavelength at 290nm, the volume of injection was 20μL and the column temperature was 30°C. The resolution between cinnamaldehyde and other peaks was good. The calibration curve was linear in the range of 0.5035~50.35μg•mL-1(r=0.99976). The average recovery (n=6) of cinnamaldehyde was 99.2% with RSD of 0.5%. The HPLC-DAD method to detect the content of cinnamaldehyde in Baoyuanqingxue granules is simple and accurate. It can be used for quality control of cinnamaldehyde in Baoyuanqingxue granules.
