一种植物提取方法
摘要：
本发明公开了一种植物提取方法，包括以下步骤：步骤1)：制备植物粗提液；步骤2)：所述粗提液经阳离子树脂和任选的阴离子树脂分离，得到收集液；步骤3)：对步骤2)得到的收集液进行浓缩处理；步骤4)：对步骤3)得到的浓缩液进行醇沉处理；任选的步骤5)浓缩干燥处理。该方法能够有效降低提取物中重金属的含量，同时大大减少提取过程中的乙醇用量，从而在提高产品品质的同时降低生产成本，有利于提高工业生产效率和安全性。
摘要（英）：

The invention discloses a plant extraction method, which comprises the following steps of a step (1), preparation of a plant crude extraction solution; a step (2), separation of the crude extraction solution through cation resin and optional anion resin to obtain a collection solution; a step (3), concentration of the collection solution obtained in the step (2); a step (4), alcohol precipitationof the concentration solution obtained in the step (3); and an optional step (5) concentration and drying. The plant extraction method can effectively reduce the content of heavy metals in extract, and at the same time, greatly reduce the using amount of ethanol in the extraction process, so as to improve the product quality and lower the production cost, and the industrial production efficiency and safety improving are facilitated.
