ABSTRACT

Objective:To optimize the extraction technology of radix scutellariae. Methods: The extraction of radix scutellariae was scanned by ultraviolet spectrophotometry from 200 to 400nm. The content of baicalin was determined by HPLC. The ultraviolet ab-sorption, baicalin content and extraction rate were used as the indices, and the optimal extraction conditions were investigated by single factor experiments and orthogonal design tests. Results: The optimal extraction conditions were as follows: the ethanol concentration was 60%, the solid-liquid ratio was 1∶40, ultrasound extraction time and temperature was 40 min and 60℃, respectively. Conclusion:The extraction of radix scutellariae has good sunscreen with promising ultraviolet absorption in UVB. Ultrasound extraction has high ex-traction yield with short time, which can be used to extract sun-screening constituents from radix scutellariae.
