目的:优化野生橄榄提取工艺。方法:利用正交试验优选野生橄榄总多酚的最佳提取工艺,以乙醇浓度、提取时间、提取温度、料液比以及提取次数对总多酚含量的影响。结果:野生橄榄总多酚最优提取工艺为:用60%乙醇、以1:20料液、70℃、提取2 h、2次。结论:优选工艺提取的总多酚含量较高,达5.75%,说明该工艺合理可行,为野生橄榄总多酚进一步研究与应用提供理论参考。
Objective: To optimize the extraction process of wild olive. Methods: The optimum extraction technology of total polyphenols in wild olive was optimized by orthogonal test. The effects of ethanol concentration, extraction time, extraction temperature, solid-liquid ratio and extraction times on the total polyphenols contents were studied. Results: The optimal extraction technology of total polyphenols in wild olives was as follows: 60% ethanol, 1:20, 70 ℃ for 2 h. CONCLUSION: The total polyphenols content of the extraction process is 5.75%, which shows that the process is reasonable and feasible, and provides a theoretical reference for the further research and application of total polyphenols in wild olives.
