Embodiment 1
[0059] The present invention is made of the following medicines in parts by weight: 800 parts of honeysuckle, 800 parts of scutellaria, and 1600 parts of forsythia.
[0060] The preparation method of Shuanghuanglian soluble powder of the present invention is:
[0061] First, decoct the honeysuckle with water for two times, the first time is 1 hour, the second time is 45 minutes, combine the decoction, reduce pressure and concentrate 1:2, cool to 45℃, add 25% lime milk to make the PH value reach 12.0, filter After adding 2 times the amount of 95% ethanol to the precipitate, place it through a 60-mesh sieve, adjust the pH to 3 with 50% sulfuric acid, stir well, filter, and neutralize the filtrate with 45% sodium hydroxide solution to a pH of 6.5. After filtration, the filtrate was concentrated under reduced pressure, dried, and set aside; Scutellaria baicalensis was decocted with water for three times, the first time was 2 hours, the second and the third time were each for 1 hour.

Abstract
The invention relates to a Shuanghuanglian soluble powder preparation technique. The Shuanghuanglian soluble powder is prepared by the following medicines with parts by weight: 800 to 1000 parts of honeysuckle, 800 to 1000 parts of radices scutellariae and 1600 to 2000 parts of fructus forsythiae; the preparation technique is characterized by comprising the steps of decocting the honeysuckle with water for two times (one hour for the first time and 45 minutes for the second time), collecting decoction, decocting the radices scutellariae with water for three times, collecting decoction, filtering, concentrating filter liquid, drying under reduced pressure, standby, grinding the fructus forsythiae, adding water and decocting for three times, depositing, filtering, and spray drying concentrated liquid which is then ground into fine powder with the extraction of the honeysuckle and the fructus forsythiae, adding proper grape sugar and obtaining the Shuanghuanglian soluble powder. The Shuanghuanglian soluble powder is characterized by high active component content, slight toxicity and side effect, no drug residues, capability of being used in the mixed feeding and drinking of large-scale culture, convenient storage and transportation, and meets the requirements of new veterinary drug preparations. The Shuanghuanglian soluble powder is applicable to curing livestock infectious diseases with determined curative effect.
Description
Technical field [0001] The invention relates to a Chinese veterinary medicine preparation with antibacterial, antipyretic and antitussive effects and its preparation process and application, in particular to the preparation process and application of Shuanghuanglian soluble powder. The invention belongs to the field of traditional Chinese medicine. Background technique [0002] Infectious diseases of the respiratory system are one of the most common diseases affecting the livestock and poultry breeding industry, especially the emergence of mixed infections, secondary infections, and drug-resistant bacterial infections in recent years, showing high incidence, complicated disease sources, and difficulty in controlling conventional drugs. Characteristics, bring serious losses to the aquaculture industry. [0003] At present, chemically synthesized non-steroidal anti-inflammatory analgesics are commonly used in the treatment of such diseases, and the drug residues are relatively seri...
