Description

Blood-activating pain-relieving tincture and preparation method thereof
Technical Field
The invention belongs to the technical field of traditional Chinese medicines, and particularly relates to a pain relieving tincture for promoting blood circulation to arrest pain and a preparation method thereof.
Background
The pain relieving tincture is a reddish brown clear liquid, has slight fragrance and pungent taste, has the effects of dispelling wind and eliminating dampness, and activating blood circulation to relieve pain, is mainly used for stomachache, traumatic injury and rheumatism osteodynia, and has obvious curative effect. The traditional preparation method of the Ketongding tincture comprises the following steps: pulverizing the rest 18 medicinal materials except Camphora and Mentholum into coarse powder; then mixing 16 medicinal materials except Camphora, Mentholum, Scutellariae radix and fructus Gardeniae, adding 80% ethanol, and sealing and soaking for 10 days; filtering the extractive solution, collecting filtrate, distilling the residue with steam, and collecting distillate; mixing the distillate and the filtrate, controlling alcohol content at 55-65%, adjusting to 400ml, adding Camphora, oleum Menthae Dementholatum, fructus Gardeniae and Scutellariae radix coarse powder in corresponding parts, stirring, sealing, soaking for 10 days, standing, and filtering. The extraction method is long in time consumption, and 80% ethanol is soaked for 10 days, so that not only the effective components but also a plurality of fat-soluble impurities are dissolved in 80% ethanol, so that the pain relieving tincture contains more impurities, suspended matters or precipitates can be generated after long-term storage, and the stability is poor; the subsequent high-temperature distillation extraction is adopted, so that the active ingredients in the medicinal materials are easily damaged, and the extraction is incomplete. Therefore, a simple and rapid preparation method of the tincture for treating the pain is urgently needed, can effectively extract the effective components in the medicinal materials, and can ensure that the tincture for treating the pain has good stability.
The principle of the supercritical carbon dioxide fluid extraction separation process is carried out by utilizing the relation between the dissolving capacity and the density of the supercritical fluid, namely, the influence of pressure and temperature on the dissolving capacity of the supercritical fluid. In the supercritical state, the supercritical fluid is contacted with the substance to be separated, so that the components with polarity, boiling point and molecular weight are selectively extracted in turn.
Chinese patent application CN1899567A discloses a kaleidoscope oil spray for traumatic injury and a preparation method thereof, the medicinal part of the kaleidoscope oil spray for traumatic injury is prepared by extracting 77 medicinal materials with supercritical carbon dioxide to obtain a fat-soluble extract and mixing the fat-soluble extract with the following medicaments, wherein the extraction conditions of the supercritical extraction are as follows: the extraction pressure is 15-40M Pa, the separation pressure is 3-8MPa, the extraction temperature is 30-60 ℃, the separation temperature is 30-40 ℃, and the flow is 26-32Kg/h for extraction for 1-5 h. The method adopts supercritical extraction of 77 medicinal materials, each of which has different effective components, and many traditional Chinese medicine effective components such as flavonoid glycosides, alkaloids, proteins, etc. with high molecular weight and water soluble substances are difficult to extract or have low extraction rate.
Although the supercritical carbon dioxide extraction has the advantages of convenient separation, low toxicity, little or even no solvent residue, and the like, and can be operated at normal temperature, the supercritical carbon dioxide extraction also has the defect of poor dissolving capacity to strong polarity, and an entrainer needs to be added. The entrainer is also called as carrying agent, and is a substance which is added into the supercritical fluid solvent, has strong affinity with the extracted substance, can be mixed with the fluid solvent, has volatility between the extracted substance and the supercritical component, and mainly aims at improving the selectivity and the solubility of the extracted substance.
Chinese patent application CN105396069A discloses a preparation method of a traditional Chinese medicine for treating chronic gastritis, the traditional Chinese medicine composition is prepared from 19 medicinal materials such as coptis chinensis, pinellia ternate, herba eupatorii, fructus amomi, salvia miltiorrhiza and the like, a preparation method combining supercritical extraction, ultrasonic extraction and reflux extraction is adopted, the content of effective components in the composition is comprehensively improved, the curative effect of a final preparation is further improved, and the traditional Chinese medicine composition has the characteristics of controllable curative effect, controllable quality and the like. However, the composition adopts 3 extraction methods, so that the active ingredients of 19 medicinal materials can be extracted to a great extent, and the method is complicated. Wherein, ethanol is selected as entrainer in the supercritical extraction, but the extracted dregs of a decoction are added with ethanol for reflux extraction, which indicates that the effective components of the medicinal materials are not completely extracted out by the supercritical carbon dioxide extraction with ethanol as entrainer.
In order to solve the technical problems, the pain relieving tincture with good stability and remarkable efficacy needs to be provided, and the preparation method of the pain relieving tincture with simple operation and high extraction rate of effective components is provided.
