preparation example

[0047] Preparation example: Preparation of acidic silica gel

[0048] I. Bake 200-300 mesh neutral silica gel in a muffle furnace at 500°C for 4 hours. After baking, cool to 260°C and keep it for 45 minutes, and finally cool to room temperature to obtain activated silica gel;

[0049] II. Add dropwise an aqueous sulfuric acid solution with a concentration of 25% by mass to the activated silica gel. The mass ratio of the activated silica gel to the sulfuric acid contained in the aqueous sulfuric acid solution is 1:0.04, then fully shake it uniformly, and vacuum dry completely to obtain Acidic silica gel.

[0050] Unless otherwise specified, the acidic silica gel used in the following examples is the acidic silica gel obtained in this preparation example.

Embodiment 1

[0052] S1: Preparation of Purple Golden Beef Root Powder

[0053] Take dried purple golden bull root with mass water content less than 2%, and use NaHCO with a mass percentage concentration of 1% 3 Soak in the aqueous solution for 20 hours, then wash it with deionized water for 2-3 times, and after it is completely dried, pulverize and pass through a 100-mesh sieve to obtain purple golden bull root powder (ie raw material);

[0054] S2: Preparation of multi-component composite extract

[0055] Mix acetone, petroleum ether and cis-3-hexenyl 2-methylbutyrate in a mass ratio of 2:1.5:1 to obtain a mixed solution; then add 5% of the weight of the mixed solution as an auxiliary 1-butanol 3-methylimidazole dicyandiamide salt, stirred and mixed for 5 minutes at room temperature, which is a multi-component composite extract;

Abstract

The invention provides a method for extracting active acid from Japanese ardisia root, and the method comprises the following steps: S1, preparing Japanese ardisia root powder; S2, preparing a multi-component compound extracting liquid; S3, preparing a crude product; S4, refining the crude product; S5, purifying and separating. The method is subject to comprehensive selection and combination of multiple extracting processes, parameters and key factors, so that respective key factors achieve an optimal coordinated effect, and a target product can be obtained with high yield and high purity, and the use ratio of raw materials is maximized, and the method has well application potential and industrialized prospect in the technical field of extracting of plant active components.

Description

Technical field [0001] The invention relates to a method for extracting active ingredients from plants, more specifically to a method for extracting an active acid from the roots of purple golden bull, belonging to the technical field of plant active ingredients extraction. Background technique [0002] In the field of plant extraction, the extraction of active ingredients from plants has become an important method for finding active ingredients in the current pharmaceutical field. For example, the common active acids in plants, such as pyrrolic acid derivatives, are a common active acid, and 4- (2-Formyl-5-hydroxymethylpyrrol-1-yl)butyric acid is a kind of pyrrolic acid substance with a variety of pharmacological activities. It has a variety of biologically active milks to protect the liver, etc. Its chemical structure is as follows: [0003] [0004] It is precisely because of the biological activity of this substance that people have carried out a lot of in-depth research on its...
