[Microwave-assisted extraction of Hesperidin from pericarpium citri reticulate]

Microwave-assisted extraction (MAE) method was studied for the extraction of Hesperidin from the pericarpium citri reticulate. Several factors, such as the concentration of extraction solvent, MAE time, MAE temperature, microwave power and liquid/ solid ratios were investigated, and the optimal conditions were obtained. The extraction percentage of hesperidiin was obtained by 2.40%, under 14 minutes extraction in 70% methanol water solvent at 65 degrees C , and the liquid/solid ratios of 25:1 (ml/g). Furthermore, compared with the other extraction methods, the MAE was more timesaving and effective. The result indicated that the MAE method is fast, efficient and energy saving, which is useful for active compounds extraction from orange peel.
