Problems solved by technology

In addition, in the analysis method, ultrasonic extraction is used to prepare the test solution twice, each time for 30 minutes, and then filtered, and the filtrates are combined and then constant volume. There are problems such as long extraction time, cumbersome operation, and the test substance is easy to remain on the filter paper.
[0004] Some scholars use HPLC to determine the content of paeoniflorin in Zishen Ningshen Pills. In the preparation of the test solution, dilute ethanol is used as the extraction solvent. After ultrasonic extraction, it is centrifuged, and the supernatant is accurately drawn to the volume. This method is cumbersome and time-consuming. long disadvantage
No durability test was conducted, suggesting that the analytical method is limited to specific conditions, and the tolerance level of the measurement results is not known, indicating that its durability is not strong, and the reliability of the analytical method cannot be guaranteed

Abstract

The invention discloses a quality detection method of kidney-nourishing and nerve-calming pills. The quality detection method comprises thin-layer chromatographic qualitative identification and content detection of schizandrin. According to the quality detection method of the kidney-nourishing and nerve-calming pills, the thin-layer chromatographic qualitative identification for prepared polygonummultiflorum and semen cuscutae in the kidney-nourishing and nerve-calming pills is firstly built, and the content measurement is performed on the schizandrin. The detection method is relatively highin specificity and durability, and the accuracy, the repetitiveness and the stability of the detection method all can meet scientific research and production requirements, so that the stability and the controllability of product quality can be effectively guaranteed.
