ABSTRACT
Objective: To optimize the extraction conditions of baicalin from Scutellariae Radix by electromagnetic pyrolysis. Method: Based on single factor experiments, taking extraction time, material size and liquid-material ratio as factors, yield of baicalin as index, extraction parameters were optimized by response surface methodology, and compared with ultrasonic method, ethanol refluxing method and decoction method. Result: The optimal extraction conditions were as follows:extraction time of 2.41 min, material size of 100 mesh, liquid-material ratio of 33 mL·g-1. Under these conditions, the yield of baicalin was 12.21%. The yields of baicalin by ethanol refluxing method, decoction method and ultrasonic method were 12.91%, 12.62% and 11.61%, respectively. The yield of baicalin by electromagnetic cracking extraction was close to several other conventional extraction methods, and the extraction time was significantly shortened. Conclusion: As a novel extraction technology of traditional Chinese medicine, electromagnetic cracking extraction has the advantages of high efficiency, energy and time saving, green environmental protection, etc. And it can provide a new method for the industrial extraction of baicalin.
