Ultrasonic Circulation Technology Crude Extract Of Rhubarb, Dried Tangerine Peel The Study Of The Active Ingredients

Tradional Chinese medicine resources are rich in Our country, using the Chinese medicine to treat disease has the glorious history; Chinese medicine permanent effect, security receive common people's attention in particular.In the world advocation nature, the return nature, gives up affectation specially in the big tidal current, the development of natural medicinal plant resources especially are important. But in the wild medicinal plant contains the ingredient to be complex, not only includes the effective component, but also includes the invalid ingredient and the toxic ingredient.Thus must through carry on its dregs to the wild medicinal plant, takes its essence the extraction process, clarifies in the medicinal plant to contain the ingredient, achieved the discernment and the correct use, can realize medicinal plant's correct use, enhance the clinical curative effect like this.Along with Chinese native medicine modernization advancement unceasingly thorough, the traditional Chinese native medicine extraction technique and the equipment have not been able to meet the need to develop completely, developed the new method and the equipment has become the Chinese native medicine modernization important link. In the recent years, the energy consumption are big in view of the traditional Chinese native medicine extraction craft in, the effective component loses, the impurity in a big way many, the efficiency low status question, had in the Chinese native medicine extraction technique and the equipment aspect progressed greatly, appeared some new methods, the new craft and the new equipment, Specially the ultrasonic wave extraction Chinese native medicine obtained the widespread application, the use ultrasonic vibration and the cavitation pressure, the high temperature effect, urges two kind of liquids, two solids, or fluid - solid, between the fluid - aerosphere surface has the member mutual seepage face shape Cheng Xin material attribute, Sped up the effective component to enter the medium, and with the medium intensive mixing, might accelerate extraction process march, enhanced the extraction rate; Therefore the ultrasonic wave extraction process has the extraction time short, the production rate high, the condition temperate and so on the remarkable characteristic.The circulation main merit is in the reactor fluid directional motion, the circulation fluid is quickly, the gas in its resident time through the way is long, the reactor was always mad including rate , the unit reactor volume air bubble surface area is big, the interaction contacts, the energy consumption is small.The supersonic circulation unified the ultrasonic wave phonochemistry function and the air type circulation, which has displayed the ultrasonic wave and the air type circulation reactor coordination effect, has provided the condition for an ultrasonic wave more effective function.This article has carried on the preliminary discussion through the experiment to the supersonic extraction of the Chinese native medicine, we has done several works:(1) We designed the ultrasonic wave - air type circulation reactor.(2) We took the supersonic electric power, the ultrasonic frequency, the ethyl alcohol density and the extraction time as experiment factor of the extraction of Chinese rhubarb dissociation anthraquinone and the flavanone material, and we gave the supersonic circulation to withdraw these two material the best factor combination, to affected the extraction the factor to carry on the analysis.(3) Under similar experimental condition to carry on the ultrasonic wave circulation extraction experiment of Chinese rhubarb dissociation anthraquinone and the flavanone class material, which the ventilation quantity is in the 0.8L/min ,we gave the best factor combination about the supersonic circulation extraction experiment, and we give the analysis about the affected factor.(4) Compared with the supersonic method extraction of Chinese native medicine and the supersonic circulation extraction , we gave the preliminary explanation about that the supersonic circulation extraction Chinese native medicine is better than the supersonic extraction Chinese native medicine, and discussed in the supersonic extraction and the supersonic circulation extraction affects the extraction the primary factor change and the reason.(5) We had discussed relations of the cavitation and the Chinese native medicine extraction, the test showed that demonstration transient state cavitation is stronger, the extraction rate is higher.
