| Abstract: |
| OBJECTIVE To study the extraction technology condition of solanesol from discarded potato leaves by microwave-assisted extraction (MAE) method. METHODS 95% ethanol was used as extraction solvent, the content of solanesol was determined by the reversed phase high performance liquid chromatography (RP-HPLC), the influence of ratio of material to solvent, radiation time, microwave power, temperature and extraction times were studied so as to analyze the factors which effect the extraction yield of solanesol by MAE, the effects of microwave-assisted extraction method was compared with those of soxhlet extraction method. RESULTS The optimum extraction parameters were chosen as follows: the ratio of material to solvent was 1∶10, the microwave power was 450 W, the temperature was 55 ℃, extraction 2 times and 20 minutes for each time. CONCLUSION The results indicate that MAE is fast, efficient, and can save energy consumption, and it has good prospects of application. |
