Abstract

The invention provides a graded extraction device for angelica dahurica leaf polysaccharide and relates to the field of angelica dahurica. The device comprises a support, the support is rotatably connected with a supporting rod, the supporting rod penetrates through a precipitation cylinder and extends into the precipitation cylinder, the interior of the supporting rod is hollow, another end of the supporting rod is connected with a medicine bottle through a medicine adding mechanism, a collecting mechanism is movably connected to the precipitation cylinder, and the supporting rod is in transmission connection with a motor through the medicine adding mechanism. According to the present invention, an agent can be quantitatively added according to the extraction progress to change the content of a polysaccharide solvent in the precipitation cylinder such that polysaccharide can precipitate, the agent does not need to be manually measured and added, and the accuracy and the labor saving are achieved. When the precipitation cylinder rotates, a semispherical bag turns over under the action of gravity, and meanwhile, a solution in the collecting mechanism flows back into the precipitation cylinder through a semipermeable membrane, the next-stage precipitation is carried out, and the collection is convenient; and the rotating precipitation cylinder can take down the precipitate collected at the previous stage while collecting the precipitate, and the collection mechanism can be replaced manually or mechanically, and the efficiency is higher.

Description

technical field [0001] The invention relates to the field of Angelica dahurica, in particular to a device for fractionating and extracting polysaccharides from leaves of Angelica dahurica. Background technique [0002] Angelica dahurica is an Umbelliferae plant, and the traditional medicinal part is its underground part "root". With the effect. In addition to being used to treat diseases, Angelica dahurica is also widely used to make spices, cosmetics and health products, etc. Although the planting area of ​​Angelica dahurica is large, the annual output of its roots still cannot meet the demand. Compared with the situation where the supply of roots is in short supply, the above-ground parts of Angelica dahurica are often discarded or burned at will, which not only wastes resources but also pollutes the environment. According to the genetic law of plants and the distribution of secondary metabolites, drugs with important pharmacological effects are often not limited to a ce...
