J. of Guangzhou Chem. Engin. 39(1), 144-145 (2011). A course on the technology of TLC/bioautography applied for the analysis of TCM was set-up to enhance students’ understanding of theoretical knowledge and to train and improve the interest and skill of students in chemical experiments. Demonstration of the TLC analysis of rutin and quercetin in Flos Sophorae on silica gel with ethyl acetate – formic acid – water 8:1:1. Detection under UV 254 nm and 366 nm, and by immersing into a solution of 1,1-diphenyl-2-picrylhydrazyl in ethanol (DPPH radical reagent). The result of this practice was satisfactory, and the course proved to be a good example to utilize the modern technology in the experimental teaching.
