| 摘 要： | 为研究不同提取方法对核桃青皮多酚提取效果的影响，以乙醇为提取溶剂，分别采用溶剂提取法、微波辅助提取法、超声波辅助提取法、六偏磷酸钠（SHMP）辅助提取法提取核桃青皮多酚。研究结果表明：在试验条件下不同提取方法对核桃青皮的影响效果不同，其中SHMP辅助微波提取法效果最好，得率为4.01?mg/g，高于对照溶剂提取法的73.4%。因此，SHMP辅助微波提取方法是一种新型高效的核桃青皮多酚提取方法。

| Abstract: | In order to research the influence of different methods on polyphenols extraction from walnut green husk, ethanol was taken as extraction solvent, and the effects of different methods (solvent extraction, microwave extraction, ultrasonic extraction and sodium hexametaphosphate extravtion) on polyphenols extraction from walnut green husk were researched. The results showed that the yield of SHMP assisted microwave extraction was found to be superior to other methods, its yield was 4.01 mg/g. The yield of SHMP assisted microwave extraction was 73.4% higher than solvent extraction. Therefore, SHMP assisted microwave extraction method is a kind of new, more efficient polyphenols extraction method from walnut green husk. |
