| Abstract: | Objective] In order to carry out the research on extraction and purification process of hesperidin in citrus peel, make full use of abundant citrus resources in Hanzhong and increase the added economical value.Method] Taking the Hanzhong citrus peel as research mate-rial, hesperidin was extracted by alkali extraction and acid precipitation method.The single factor experiment was carried out with the kinds of alkali, alkali content, extraction temperature, extraction time and the ratio of material to liquid.Alkali dosage, extraction temperature, ex-traction time and solid-liquid ratio were studied by L9 (34 ) orthogonal test to optimize the extraction technology of hesperidin.The ultra per-formance liquid chromatography was used to test the optimization results . Result] The sequence for the factors affecting extraction and purifi-cation process of hesperidin in citrus peel was extraction time, alkali weight, extraction temperature and the ratio of material to liquid.When the process conditions were 0.08 g of Ca(OH)2 per gram citrus peel, extraction time 0.5 h, temperature 30 ℃, and the material and liquid ratio 1∶30 g/mL, the best extraction effect could be obtained.The yield rate of crude product was 4.5%.Conclusion] The optimization pa-rameters and extraction process obtained in the test were stable, and the operation of selected equipment was simple and rapid, which had good application prospects. |
