Objective:To develop the qualitative and quantitative methods for Qingyan spray.Methods:Figwort root
Honeysuckle flower
Baikal skullcap Root in the spray were identified by TLC.The content of Andrographolide was determined by HPLC.Results:The TLC methods for the indentification of Figwort root Honeysuckle flower Baikal skullcap Root was reliable and specific.The calibration curve for Andrographolide was linear in the range of 48.1~240.3 μg/ml(r=0.999 9).The average recovery of Andrographolidewas 100.1%(RSD=0.32%).Conclusions:The methods can be applied to the quality control of Qingyan Spray.
