Embodiment 1

[0016] A percolation extraction method of belladonna extract, comprising medicinal material treatment, wetting, packing, percolation, and preparation of dry extract; the medicinal material treatment process is to take belladonna roots, remove impurities and mildewed parts, and use Take out after washing with a saline solution with a mass concentration of 3%, the water content of the roots of belladonna washed with a saline solution is 25-30%, and knead with a kneading machine. The kneading machine is a crank rocker type root class Chinese medicinal material kneading machine, and the feeding rate is 800kg / h;

[0017] Wetting: Spray water equivalent to 35% of its weight into the belladonna rubbing silk. During the spraying process, turn the belladonna rubbing silk to make it wet evenly; then keep it in a sealed tank with a humidity of 65%. In 25 minutes, wetting material was obtained;

[0018] Packing: after padding the absorbent cotton, load the wet material several times. The...

Abstract

The invention belongs to the technical field of atropa belladonna extract extraction, and concretely relates to a percolation extraction method of atropa belladonna extract. The percolation extractionmethod comprises the steps of medicinal material treatment, wetting, barreling, percolation, and dry extract preparation, and the medicinal material treatment process comprises the steps of taking roots of atropa belladonna, removing impurities and mildewed parts, washing with a saline solution with the mass concentration of 3%, taking out, rubbing with a rubbing machine, and removing non-shredded parts after rubbing to obtain atropa belladonna rubbing shreds; wherein the percolation speed and the solvent temperature are adjusted in the percolation process. Compared with the prior art, the method has the following advantages that the impregnation time and the percolation time can be shortened, and meanwhile, the obtained dry extract can meet the provisions about the belladonna herb dry extract; the extraction time can be shortened by about a half from the traditional 10h, 168-173g of dry extract can be prepared by rubbing every 1000g of atropa belladonna shreds, and the yield of hyoscyamine reaches 85.5% or above.

Description

technical field [0001] The invention belongs to the technical field of extraction of belladonna extract, in particular to a percolation extraction method of belladonna extract. Background technique [0002] The active ingredient of the traditional Chinese medicine belladonna is hyoscyamine. The conventional extraction method is the percolation method, but the extraction time is longer, which affects the extraction efficiency. In the prior art, in order to improve the extraction rate, ultrasonic extraction is used. The paste meets the requirements, that is, every 1g extract contains more than 5g of belladonna, which can greatly shorten the extraction time; the percolation method in the prior art uses 85% ethanol as a solvent for the belladonna coarse powder, impregnated for 48 hours, with 1 -3mL / min speed percolation, percolation time is 10 hours, per 1000g belladonna coarse powder dry extract amount 163.2g, yield is 81.60%; but in practical application, due to the larger dia...
