Abstract

The invention discloses a quality detection method of berberis poiretii schneid and purslane prepared granules. The quality detection method comprises the following steps: a, preparing a test solution; b, preparing a reference substance solution : using threonine, leucine and berberine hydrochloride as reference substances, dissolving the reference substances to prepare the reference substance solution; c, detecting: dipping the test solution and the reference substance solution on a silica gel G thin layer plate, using n-butyl alcohol-acetic acid-ethanol-water as a developer, developing, taking out the plate, drying, spraying 0.2% of a ninhydrin ethanol solution, heating the plate plate at the temperature of 110 DEG C until the spots are developed clearly. The quality detection method disclosed by the invention is used for detecting threonine, leucine and berberine hydrochloride, meanwhile controlling the quality of berberis poiretii schneid and purslane in the berberis poiretii schneid and purslane prepared granules, and further effectively controlling the quality of the berberis poiretii schneid and purslane prepared granules; the quality detection method is simple and convenient to operate, quick in detection speed, and good in application prospect.
