The extraction results of total alkaloid content under different conditions show that the extraction temperature, pH, extraction time and solvent volume have impacts on total alkaloid content to some degree, which are all obvious to see. The best design scheme through analysis of orthogonal test is to use acid water as solvent, set extraction temperature as 60℃, extraction time as 1h and solvent volume is 90mL while the pH is 2.
