Abstract:ObjectiveTo prepare the Sauropus spatulifolius Beille dispersing granules and determine its quality,to provide the basis for the quality analysis.MethodsSauropus spatulifolius Beille dispersing granules were prepared by boiling water extraction method of crude drug,and the suitable HPLC method was established.The content of kaempferol -3-O-gentiobioside of Sauropus spatulifolius Beille dispersing granules was determined by using methanol and 0.4% phosphoric acid solution in accordance with the proportion of 48∶52.ResultsThe linear range of kaempferol-3-O-gentiobioside was 0.1208-1.098 μg,r=1.002.The relative standard deviation was 1.03%.ConclusionThe preparation and quality analysis method of Sauropus spatulifolius Beille dispersing granules established in this study is accurate and reliable,it can lay a foundation for further analysis and research.
