Abstract
This research established an easy method to retrieve scutellarin from the acid precipitation waste liquid. The waste liquid in scutellarin production process was collected and concentrated. Then, it was added with one to five times volume of distilled water and the coarse-grain of scutellarin was collected as the sediment. Finally, the scutellarin with high purity (90.1-90.2%) was retrieved by recrystallization with absolute ethyl alcohol. The content of scutellarin in every step was determined by HPLC-UV method. This is a handy method to retrieve scutellarin from the acid precipitation waste liquid and it can increase the availability of crude material.
