Study on identification of compound Shanqidan capsules by ultraviolet spectrophotometry

Objective： To dynamically analyze the spectrum of all components in compound Shanqidan capsules by ultraviolet（ UV ）spectrophotometry and to provide a reference for the quality assessment of compound Shanqidan capsules. Methods： Three batches of compound Shanqidan capsules were subjected to ultrasonic extraction using water, anhydrous ethanol, chloroform,and petroleum ether and were then examined by UV spectrometry ;first and second derivative analysis was performed on the characteristic absorption. Results： The characteristic data of UV absorption spectrum of compound Shanqidan capsules had high reproducibility, high resolution, and strong characteristics. Conclusion： This method is simple,accurate,and sensitive and can be used for identifying compound Shanqidan capsules.
