In this method, a special double solid membrane was prepared to extract four alkaloids. After extraction, the Solid phase microextraction (SPME), was first introduced enriched target analytes on the membrane were dissociated by Arthur and Pawliszyn in the early 1990s [1], which is by methanol and analyzed by HPLC. The main variables a simple, fast, and efficient sample preparation technique affecting the method were investigated and optimized. that eliminates the need for solvents and integrates sam- Under the optimized conditions, linear range of coptisine pling, isolation, and enrichment http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Chromatographia Springer Journals
