A novel effervescent-salt-assisted dispersive micro-solid-phase extraction using mesoporous hybrid materials was developed for the extraction of minute traces of constituents in complicated plant preparations. In this study, a special tablet containing carbon dioxide sources (sodium dihydrogenphosphate and sodium carbonate) and the sorbent (mesoporous hybrid materials) was prepared. The effects of different parameters influencing the extraction efficiency such as the concentration of salts, the type and concentration of mesoporous material, pH of diluent, and desorption solvents were investigated and optimized. Results show that the proposed method using green solvents (water) as extraction solutions required low consumption of sample amount and obtained high enrichment efficiency. Moreover, under optimized conditions, the tested tanshinones exhibited good linearity (r (2) > 0.994) in the concentration range of 0.5 to 80 ng mL(-1). The limits of detection values were lower than 0.0803 pg using UV-visible detection. The developed method was successfully applied for the analysis of trace tanshinones in compound Danshen dripping pill and Danqi tablet samples.
