Embodiment 1

[0022] The extraction and processing method of Houttuynia cordata in the formulation of antiviral particles includes the following steps:

[0023] (1) Place Houttuynia cordata in a stainless steel extraction tank, add production water 8 times the weight of Houttuynia cordata, boil for 45min, and release the medicinal liquid for filtration;

[0024] (2) Put the medicinal liquid in a stainless steel open steam pot, heat and concentrate it to a clear paste with a density of 1.03 (measured with a Pomei hydrometer at 60-70 °C), and then put the clear paste into a stainless steel bucket Internal cooling to room temperature;

[0025] (3) Add 95% ethanol of 1.2 times the weight of the clear paste to the clear paste under stirring, and then let it stand for more than 24 hours;

[0026] (4) Use a centrifuge for separation, and then discard the sediment;

[0027] (5) After evaporating and recovering the ethanol in the liquid separated in step (4), the Houttuynia Herbs liquid is obtaine...

Abstract

The invention discloses an extracting treatment method of cordate houttuynia in an antiviral particle formula, which is used for solving the problems of the existing cordate houttuynia extracting process that production cost of drug is high and the drug quality is unqualified. The extracting treatment method comprises the following steps of: firstly, boiling and extracting the cordate houttuynia material by using water as a solvent; then, carrying out a precipitation process by adopting alcohol and carrying out separation by adopting a separator; and finally, evaporating and recycling alcohol from the liquid to obtain the cordate houttuynia liquor. By the extracting treatment method, cordate houttuynia products can be contained in the traditional Chinese preparation; the cordate houttuynia can be extracted by adopting water as a solvent independently, wherein the water is cheap and easily available, the heating and extracting time is short and the efficiency is high. Besides, the density of the particle liquid medicine containing cordate houttuynia prepared by the extracting treatment method disclosed by the invention is extremely high and the auxiliary agent is greatly reduced, so that the pesticide effect is improved and the production cost is lowered. Moreover, the prepared particle form is good in solubility, so that the quality of the product is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to a method for extracting and processing Houttuynia cordata in an antiviral particle formulation. Background technique [0002] Traditional Chinese medicine granules are the mainstream dosage form in the domestic pharmaceutical market due to their fast absorption, good curative effect, and convenience in taking and carrying. The conventional practice of granules is: decoct all the traditional Chinese medicines in the formula, concentrate the filtrate into a thick paste with a relative density of 1.30-1.35, and add 4-5 times the amount of adjuvant to the thick paste to make granules. The core of this process is that the relative density of the thick paste should be 1.30-1.35. The granules made in this way can be products with high drug content, good solubility, low dosage and the best quality. [0003] When the applicant was engaged in the development of antiviral gra...
