Abstract
BackgroundExtraction of active compounds from plants using microwave can be utilized as an alternative solution for conventional extraction. To well understand this technology, the study of the modelization and kinetics mechanism of the extraction method is necessary. This study aimed to evaluate the suitable kinetics models for MAE of the Xanthones from Securidaca longepedunculata Fresen roots.ResultsThe experimental data (xanthones versus time, power and ratio, respectively) were fitted to three-parameter empirical kinetics models. The second-order models appear to be the best fit to explain kinetics study of MAE than the first model. The second-order model was acceptable, with elevated value of the correlation coefficient (R2 = 0.9861), showing that it perfectly relates the process.ConclusionBased on the results obtained, the extraction of xanthones from roots of S. longepedunculata is done successively in two steps, washing and diffusion of compounds from matrices as described by second-order kinetics model. The latter could report the kinetics model of extraction process from S. longepedunculata Fresen using microwave technology.
