Abstract

The garlicin emulsion injection is a kind of water base dispersion; has dispersed phase of average size smaller than 1 micron, and with garlicin in 0.5-2.5 weight portions, emulsifier for injection 0.2-7.5 weight portions, co-emulsifier 0-3 weight portions, oil phase dispersing medium 5-20 weight portions and isosmotic agent 0.5-3 weight portions; and contains garlicin in 1-20 mg / ml. The preparation process includes mixing garlicin, emulsifier, co-emulsifier, oil phase dispersing medium and isosmotic agent and adding water for injection; ultrasonic crushing to form initial emulsion and further emulsification in high pressure emulsifying machine to form water base dispersed phase of average size smaller than 1 micron; regulating pH to 5-7, microporous film filtering, packing and sterilizing to obtain garlicin injection. The present invention solves the problem of poor water solubility and less stimulation to blood vessel and raised garlicin stability.

Description

technical field [0001] The invention relates to an allicin injection emulsion and a preparation method thereof, belonging to the technical field of medicine. Background technique [0002] Allicin is the main component of garlic volatile oil obtained from underground bulbs of Allium Satirum L., which is a plant of the genus Allium in the Liliaceae family, after crushing and steam distillation. The English name of allicin is Allitride, and its chemical name is trithiodipropylene. for C 6 h 10 S 3 , the molecular weight is 178.33, and the molecular structure formula is as follows: [0003] [0004] Allicin is mainly used for sterilization. It is known as a natural "broad-spectrum antibiotic" in nature. It has inhibitory and killing effects on a variety of bacteria and fungi. It can be used to treat dysentery and enteritis. In recent years, allicin has also been used clinically. used in the treatment of tumors. In addition, allicin also has the effects of improving the b...
