Problems solved by technology

[0005] Therefore, this problem must be solved as soon as possible. At present, most of the pesticide residues in ginseng extracts exceed the standard, and some of them are processed by repeated extraction with n-hexane to deal with pesticide residues, but the effect is very small. The problem of poor operability

Abstract

The invention relates to the technical field of biological medicines, in particular to a preparation method of a low-pesticide-residue ginseng root extract, which comprises the following steps: S1, selecting cleaned ginseng raw materials, shearing roots of the ginseng raw materials, crushing the ginseng raw materials into coarse powder by a crusher, and then adding water and mixing to obtain a to-be-extracted initial solution; S2, adsorption treatment: carrying out macroporous resin D101 adsorption on the specifically obtained extracting solution, analyzing with ethanol, filtering with a plate frame, and concentrating; S3, pesticide residue removal treatment: diluting the obtained concentrated solution with water, removing pesticide residues with resin, and then carrying out secondary concentration treatment; and S4: finished product preparation: performing vacuum drying on the secondary concentrated solution obtained in the step S3, then performing crushing, and finally performing sieving to obtain an extract finished product. According to the technical scheme, the preparation method of the low-pesticide-residue ginseng root extract is high in pesticide residue removal treatment efficiency and low in organic solvent residue content, and meanwhile, the ginsenoside content of the ginseng extract is not lower than 55% HPLC.

Description

technical field [0001] The invention relates to the technical field of biomedicine preparation, in particular to a preparation method of ginseng root extract with low pesticide residues. Background technique [0002] With the development of agricultural industrialization, the production of agricultural products is increasingly dependent on exogenous substances such as antibiotics and organic pesticides, and the large-scale use of pesticides will inevitably lead to the problem of excessive pesticide residues in agricultural products, affecting the food safety of consumers, and in serious cases. consumer life. In addition, many countries have strict restrictions on the amount of pesticide residues in natural plant products. Excessive pesticide residues directly affect the export of products and cause trade problems. [0003] The found active ingredients of total saponins in ginseng stems and leaves are mainly ginsenosides, which have the effects of nourishing and strengthenin...
