目的 :研究影响锦灯笼匀浆提取工艺研究的因素并确定最佳提取工艺。方法 :以木犀草苷的含量为评价指标,研究了提取次数、提取时间、固液比等不同影响因子对提取效果的影响,确定匀浆提取适宜条件。结果 :优化的提取条件以液固比(mL:g)为15∶1加入体积分数为80%的乙醇,匀浆3 min,提取2次。结论 :匀浆提取比其他常规提取方法操作简单,省去了对物料进行烘干、粉碎的步骤,并使物料破碎和有效成分的提取同步进行,是一种对植物有效成分提取速度快、强度高的方法。
Objective: To study the factors that affect the extraction process of Jin lantern homogenate and determine the best extraction process. Methods: The content of luteolin was used as the evaluation index to study the influence of extraction time, extraction time, solid-liquid ratio and other influencing factors on the extraction efficiency, and to determine the suitable conditions for homogenate extraction. Results: The optimal extraction conditions were as follows: the volume fraction of 80% ethanol was added at a ratio of liquid to solid (mL: g) of 15:1, homogenized for 3 min and extracted twice. Conclusion: The homogenate extraction is simpler than other conventional extraction methods, eliminating the need for steps of drying and comminuting the material, breaking the material and extracting the active ingredients simultaneously. It is an effective method to extract the active ingredients of plants with high speed, High way.
