Abstract

The invention discloses a preparation method of a pyrolin microcapsule, wherein a microcapsule structure is formed by wrapping pyrolin with gelatin. The pyrolin is a traditional Chinese medicine effective component obtained by artificial chemical synthesis and has strong antibacterial activity; the microcapsule is used as a drug carrier, and has many characteristics of drug stability improvement, sustained or controlled release effect, targeted property, high bioavailability and the like superior to those of a traditional preparation; the pyrolin microcapsule can effectively improve the stability of drug preparation, changes the taste sense, and can be applied to a clinical new preparation.

Description

technical field [0001] The invention belongs to the field of veterinary drug research, and in particular relates to a preparation method technology of wintergreen microcapsules. Background technique [0002] Wintergreen, also known as little guohun grass and diarrhea grass, is a plant of the wintergreen family. Traditional Chinese medicine generally uses it in combination with other medicines for dispelling rheumatism, tonifying the kidney, and stopping bleeding. Single wintergreen has the functions of nourishing the waist and kidneys, promoting blood circulation and regulating menstruation, but there are few records of treating acute infections. In 1957, Mr. Bao Youdi, a Chinese scholar, conducted an antimicrobial experiment on its single prescription, and the results showed that the effect of wintergreen on various types of Shigella was better than that of sulfonamides, synmycin, streptomycin, aureomycin, and berberine , Plantain, etc. In the same year, the Department o...
