Abstract
The invention relates to a vitex oil nanoemulsion and a preparation method and application thereof. The preparation method is characterized in that the advanced nanotechnology is used for the formula and process design of the vitex oil nanoemulsion. The preparation method comprises the steps that: vitex oil, medium chain fatty acid triglyceride, soy lecithin, ethanol and the like are evenly mixed to be used as an oil phase; poloxamer is mixed with water and the like to be used as a water phase; the oil phase is added to the water phase to be mixed and emulsified at a temperature of 40 to 60 DEG C and be treated by a two-step high-pressure homogenizer to obtain the milk-white vitex oil nanoemulsion with the average particle size of less than 100nm. The vitex oil nanoemulsion prepared by the invention has high quality, reliable quality stability and good biocompatibility, and simultaneously has good expectorant, antitussive and antiasthmatic effects.
Description
Technical field
The present invention relates to a kind of vitex oil nanoemulsion and its production and application, belong to medical technical field.
Background technology
Chinese medicine is the rarity of Chinese traditional culture, in China long history in several thousand is arranged, and its unique drug effect is very important at world medical circle.Traditional Chinese medicine preparation dosage form mostly is decoction, pill, electuary, powder etc.Traditional heating means make its bioactive ingredients destroyed easily, and mouthfeel is not good and dosage is big, and body absorption rate is low, is difficult to give full play to its usefulness.Especially liquid oiliness Chinese medicine comprises Chinese medicine unsaturated fatty acids oil and volatile oil, has stronger physiologically active usually, but relatively more responsive to air, light and temperature, easily oxidation Decomposition is rotten.Therefore, the development of Chinese medicine preparation presses for modern formulation and combines.Nanotechnology is a kind of effective ways that change medicine existence in preparation.The suitable dosage form of applying nano technology preparation makes oiliness Chinese medicine nanometer emulsified, and then makes injection, oral agents or transdermal agent, can overcome himself shortcoming, significantly improves its physicochemical property, prolongs to store the time limit, enlarges range of application.At present, nano-emulsion has shown comparatively remarkable advantages in the intravenously administrable carrier as traditional medicine volatile oil and poorly water soluble drugs, cause vast medical worker's concern.
Oleum Viticis Negundo is the fresh leaf of Verenaceae plant Herba Viticis Cannabifoliae, the volatile oil that obtains through vapor distillation.Oleum Viticis Negundo eliminates the phlegm, antitussive action is stronger, and more weak antiasthmatic effect is also arranged.Viticis Negundo Oil Emulsion is the oral latex emulsion that is come through form improvement by pharmacopeia kind viticis negundo oil capsules.Viticis Negundo Oil Emulsion is to adopt Oleum Viticis Negundo that emulsifying technology will have a drug effect to be dispersed in the water Emulsion for preparing with the form of droplet.Compare with viticis negundo oil capsules, Viticis Negundo Oil Emulsion is taken medicine conveniently, and the patient of the pill that is particularly useful for being bad at swallowing takes, and is the ideal medicament of chronic pneumatic tube inflammation of treatment.
Summary of the invention
The objective of the invention is advanced person's nanotechnology is used for the prescription and the technological design of Oleum Viticis Negundo Emulsion, best in quality, quality stability is reliable, good biocompatibility thereby prepare, and have simultaneously good eliminate the phlegm, the vitex oil nanoemulsion of cough-relieving, the effect of relievining asthma.
The technical solution adopted in the present invention is: a kind of vitex oil nanoemulsion and preparation method thereof is characterized in that this vitex oil nanoemulsion contains following component:
Oleum Viticis Negundo 1%-15%
Medium chain length fatty acid triglyceride 15%-30%
Soybean phospholipid 1%-4%
Vitamin E 0.1%-0.2%
Oleic acid 0.25%-0.5%
Sorbic acid 0.05%-0.20%

Water 40%-60%
Its preparation methods steps is as follows in the vitex oil nanoemulsion of the present invention:
(1) with 1%-15% Oleum Viticis Negundo, 15%-30% MCT Oil, 1%-4% soybean phospholipid, 0.25%-0.5% oleic acid, 0.1%-0.2% vitamin E, 0.05%-0.2% sorbic acid, 0.1%-1% Mentholum and 10%-20% ethanol mixed dissolution, 40 ℃-60 ℃ insulation 30min, preparation obtains oil phase.
(2) 0.1%-0.5% polyvidone and 1%-6% poloxamer are dissolved in the part pure water (account for Emulsion final volume 40%), 40 ℃-60 ℃ insulation 30min, preparation obtains water.
(3) with the oil phase of above acquisition while hot, under stirring, slowly add aqueous phase, obtain colostrum.
(4) colostrum for preparing more than the general after two circulations of high pressure homogenize (500bar-1000bar), is added pure water, adopts sodium hydroxide solution to regulate pH to 7.5, standardize solution.With the above emulsion that obtains, four circulations of high pressure homogenize (500bar-1000bar) obtain outward appearance and are milky white shape, and mean diameter is less than 100nm, stay-in-grade vitex oil nanoemulsion.
Vitex oil nanoemulsion of the present invention can adopt 100 ℃ of flowing steam 30min, sterilizes.Vitex oil nanoemulsion of the present invention has effectively solved the stability problem of Oleum Viticis Negundo Emulsion in long-term the placement.In the long term store process, can keep the emulsified state of homogeneous, meet in the Chinese Pharmacopoeia rules of preparations requirement to Emulsion: the centrifugal 15min of 4000rpm, Emulsion is not stratified.Thereby a kind of good biocompatibility is provided, and have simultaneously good eliminate the phlegm, the vitex oil nanoemulsion of cough-relieving, the effect of relievining asthma, improved compliance of patients.
