Objective： To investigate the optimal water extraction process of Jinyin Lidan oral liquids. Methods： An orthogonal design was used in the extraction optimization using the yield and content of chlorogenic acid,narigin and neohesperidin as the evaluation indices and the volume of water,extraction times,extraction time and soaking time as the influencing factors. The contents of chlorogenic acid,narigin and neohesperidin were detected by HPLC to screen the best extraction technology. Results： The best water extraction conditions were as follows： the amount of the added water was 8 times of the medicinal materials,the soaking time was 1 h,and the decoction was carried out twice with the duration of 1. 5 h for each. Conclusion： The process is stable and reasonable,which provides research foundation for the production and quality control.
