ABSTRACT
In this study, the effect of various parameters such as solvent concentration (50 and 80%), extraction temperature (30, 40, and 50°C), and solvent/solid ratio (1:20, 1:25, and 1:30 g ml−1) on the extraction yield of apigenin-glycosides from parsley were investigated. The high-performance liquid chromatography analysis of parsley extracts confirms the presence of two apigenin-glycosides: apiin and malonyl-apiin. The kinetics of extraction was described using non-stationary diffusion model and Ponomarev’s model. Models have a good fit to the experimental data (root mean square: RMS<±1.6%; standard deviation: SD<±1.5%; the coefficient of determination: R2 > 0.82). The effects of the process factors on the kinetic model parameters, equilibrium constant and Gibbs free energy change were assessed using the full factorial test plan 23.
