Study on Quality Standard of Longchuancaogutong Granule
Abstract:ObjectiveTo establish a standard for the quality control of Longchuancaogutong Granule.MethodsRamulus Cinnamomi, Radix Achyranthis Bidentatae, Ru Xiang,Mo Yao and Rhizoma Corydalis were identified by TLC,and the control of Chlorogenic acid in Cortex Eucommiae was determined by HPLC. ResultsThe calibration curve was linear in the range of 1.62~21.60 μg(r =1.0000).The average recovery of the method was 98.7%,RSD was 2.29%(n =5). ConclusionThis method is reliable and accurate, and can be used for the quality control of this preparation.
