Abstract

The invention discloses a content determination method for paeoniflorin and calycosin-7-glucoside in a traditional Chinese medicine preparation. According to the method, the content of the paeoniflorin and the calycosin-7-glucoside in Xiaokeling tablets and Xiaokeling capsules is detected by adopting a high-performance liquid chromatography, and effective evidence is provided for inspecting whether enterprises have no material feeding or less material feeding and poor-quality medicinal material feeding behaviors or not. According to the content determination method, detection conditions are improved and a solution preparation method is optimized according to Volume Four 0512 of Pharmacopoeia of the People's Republic of China of 2015 Edition, so that the determination method is more efficient and more accurate and the determination method has specificity and no interference on negative control.

Description

Technical field [0001] The invention relates to a method for detecting traditional Chinese medicine preparations, in particular to a method for determining the contents of paeoniflorin and verbasil glucoside in Xiaokeling tablets and Xiaokeling capsules.
