Chinese medicine extraction technology to extract ranunculaceae plants
Dan were phenol is extract from the Chinese peony root bark of a kind of traditional Chinese medicine. Extracted from ranunculaceae plant peony root dry skin. For pressure tail, acetic acid caused by physical or chemical factors such as pain, has obvious analgesic action. At present, the injection is the main clinical medicine formulations were, in both analgesic and dermatology clinical widely used. Drugs were outlook has involved daily hair care, skin care, beauty, and other products.

the properties were white or light yellow luster were needle crystal, colorless needle crystal ( Ethanol) Scientific name, Chinese 2 & # 39; - Hydroxy - 4 '- Methoxy acetophenone. 49 ℃ - melting point 51 ℃ and a special smell, taste spicy, soluble in ethanol and methanol, soluble in ether, acetone, benzene, chloroform and carbon disulfide, slightly soluble in water, dissolved in hot water, insoluble in cold water, can with the steam evaporation. Extraction and separation of


a, water vapor distillation according to Dalton's law, if the liquid mixture between don't dissolve each other don't respond to each other, and they are the sum of total pressure is equal to the sum of each component pressure under this temperature, when the sum of the components of saturated vapor pressure is equal to atmospheric pressure, the liquid mixture begins to boil and distilled out.
will contain volatile medicinal powder, after soaking, directly through the water vapour distillation, and then collect condensate after condensation, distillation for many times repeatedly, can increase the concentration of the effluent and purity, but distillation times is unfavorable and overmuch, avoid some of raw material composition oxidation and decomposition.
advantage: the extract of high purity, the experiment of low cost, no special instrument, is a kind of ideal extraction test method.
2, CO2 supercritical fluid extraction
CO2 supercritical fluid extraction method is to pass under a certain temperature, constantly increasing pressure, the gas into a liquid. Because the material has a critical temperature and critical pressure, higher or regional critical temperature and pressure, measured material won't translate into liquid. According to different material point, the purpose of extraction.
by carbon dioxide extraction was carried out on the material, the extraction method for low temperature, closed the whole process, to achieve extraction cortex moutan.
advantage: safety, fast extraction, high purity, no chemical pollution.

3, solvent extraction method with anhydrous ethanol as solvent, reflux extraction under certain temperature, it can be extracted were. Its craft is simple, is to extract the effective components, but also pay attention to the cortex moutan, low melting point, volatile phenol, avoid to remove ethanol should be paid attention to in the actual production and lost a lot of, were in the extraction of the higher the heating temperature, the longer the time, the yield of were lower.
advantages: simple process, low cost, easy industrial production.
summary: solvent extraction, extraction method is an ideal experiment, in the face of today's industrialized mass production, the solvent extraction method is not very ideal extraction methods were. And solvent extraction process is simple, as long as grasp the low melting point, were volatile features, is easy to implement mass production.
centrifugal extraction machine application of traditional Chinese medicine extraction technology
were extracted with the progress of science and technology, centrifugal extraction machine widely used in the industries of traditional Chinese medicine extraction. Machine is a kind of centrifugal extraction by liquid-liquid extraction, a new type of centrifuge solid-liquid extraction. By adding extraction agent, the two-phase mixture of liquid under the action of centrifugal force field, achieve statified phenomenon, so as to achieve extraction purpose. For the present stage of Chinese traditional medicine extraction process, has the advantage of its natural. Its material adaptability is strong, high flexibility, short contact time two phase material, extraction reagent cost less, very suitable for industrial production.








DE source extraction to recommend Chinese medicine extraction technology to extract ranunculaceae plants help you understand were extraction equipment and production capacity, technological process, characteristics of the equipment, such as detailed specification, at the same time can also see the relevant customer case and extraction equipment solution, the research trend, you can also browse all extraction equipment.
