Abstract
The production process for preparing fine ephedra powder and its by-product tanning matter by using macroporous resin method includes the following steps: (1). breaking Chinese ephedra herb and extracting according to the conventional extraction process of ephedrine; (2). straining the digested liquor, regulating pH value by using hydrochloric acid, precipitating and taking supernatant fluid, and making one pass through macroporous adsorption resin bed; (3) concentrating the solution flowed from the macroporous adsorption resin bed, spray-drying to obtain the fine ephedra powder; (4) using ethyl alcohol to elute the material adsorbed on the macroporous adsorption resin bed, recovering ethyl alcohol, spray-drying to obtain the by-product tanning matter.
Description
The present invention relates to a kind of new process of production with method for preparing Ephedra sinica fine powder and byproduct tannin thereof.
Chinese ephedra is China's special product and world-famous a kind of Chinese medicine, just is used as the peaceful antiasthmatics of coughing of sudorific before four over thousands of years.Ephedrine is an adrenomimetic drug.There is a large amount of Chinese ephedras provinces and regions such as the Inner Mongol of China, Liaoning, Qinghai, and resource is extremely abundant, about more than 300 tons of year production racephedrine.Along with the growth of world market to the Chinese ephedra powder demand of 4-10%, a roughing factory that criticizes very much the Chinese ephedra powder produces immediately in recent years, its fair≤4% (Chinese ephedra total alkali).Because total alkali is low thereby earn foreign exchange fewly, what bring enterprise is low profit high energy consumption.In addition, mensuration, analysis through to ephedra sinica, epheday intermedia and ephedra equisetina all contain higher tannin, are respectively 6.5%, 7.6%, 7.4%; And these tannins all are wasted when roughing Chinese ephedra powder, and do not make full use of.Tannin is the important source material of oil production, light industry and medicine.Usually the production of tannin needs starting material such as a large amount of barks, and this is a kind of extremely harmful production that destroys the limited forest reserves.And the tannin of high level is corrosive to used vessel in the extraction of extracting racephedrine, the separation production process.If can produce on the Chinese ephedra powder craft basis at primary be that poach is carried, after filtration, concentrate drying or the spraying drying product≤4%, this resource of comprehensive development and utilization Chinese ephedra is extracted its byproduct tannin simultaneously, can reduce cost like this and can reduce the wasting of resources again.
The present invention seeks to utilize in order to provide a kind of that existing technology basis comprehensive utilization Chinese ephedra resource, less investment, power consumption are low, the method for preparing Ephedra sinica fine powder of instant effect and the new process of production of byproduct tannin thereof.
Purpose of the present invention can realize by following measure:
The new process of production of a kind of method for preparing Ephedra sinica fine powder and byproduct tannin thereof contains following processing step: 1. with the Herba Ephedrae fragmentation, put forward technology by the conventional boiling water cover of racephedrine and extract; 2. with after the vat liquor coarse filtration, transferring pH value with hydrochloric acid is 5-8, draws supernatant liquor through post precipitation and crosses the macroporous adsorbent resin bed; 3. the effluent liquid of macroporous adsorbent resin bed gets Ephedra sinica fine powder after the concentrating under reduced pressure spraying drying; 4. it is closely colourless the adsorptive on the macroporous absorption village fat bed to be washed to effluent liquid; Use the adsorptive on the ethanol elution macroporous adsorbent resin bed again; Behind the decompression recycling ethanol, spraying drying gets the byproduct tannin.
The present invention has following advantage compared to existing technology:
1, the present invention is on the extraction process basis of existing Chinese ephedra powder, add one vat liquor and cross the operation of macroporous adsorbent resin bed, thereby the byproduct tannin of losing in the Chinese ephedra powder abstraction process is adsorbed, and can utilize again, the Chinese ephedra total alkali that can improve the Chinese ephedra powder like this reaches 6-10%, and can reclaim the byproduct tannin of polymeric adsorbent bed absorption simultaneously, and its tannin content can reach 56.4%.
2, after tannin of the present invention is adsorbed, avoided extraction, when separating the Chinese ephedra powder to the corrosion of iron appearance ware.
3, simple, the less investment of technology of the present invention, power consumption is low, income is big.
The present invention also will be described in further detail in conjunction with the embodiments:
Embodiment:
The new process of production of a kind of method for preparing Ephedra sinica fine powder and byproduct tannin thereof contains following processing step: 1. with the Herba Ephedrae fragmentation, put forward technology by the conventional boiling water cover of racephedrine and extract; 2. with after the vat liquor coarse filtration, transferring pH value with 5% hydrochloric acid is 7, draws supernatant liquor and cross the D101 macroporous adsorbent resin bed that the Tianjin glue works is produced after natural sedimentation, and its adsorptive capacity is 10g/100ml; 3. the effluent liquid of macroporous adsorbent resin bed gets Ephedra sinica fine powder after conventional method concentrating under reduced pressure spraying drying; 4. it is closely colourless the adsorptive on the macroporous absorption village fat bed to be washed to effluent liquid; Use the adsorptive on the 86% ethanol elution macroporous adsorbent resin bed again; Behind the decompression recycling ethanol, the ordinary method spraying drying gets the byproduct tannin.Adopt this production technique per kilogram Herba Ephedrae to get: Ephedra sinica fine powder 75g, yield 7.5%, tannin 98g, yield 9.8%; It is 10% that total alkali titration is surveyed Ephedra sinica fine powder epheday intermedia total alkali, and content of tannin is 56.4% in the complexometry survey tannin extract product.
Claims (2)
1, the new process of production of a kind of method for preparing Ephedra sinica fine powder and byproduct tannin thereof, its feature contains following processing step: 1. with the Herba Ephedrae fragmentation, put forward technology by the conventional boiling water cover of racephedrine and extract; 2. with after the vat liquor coarse filtration, transferring pH value with hydrochloric acid is 5-8, draws supernatant liquor through post precipitation and crosses the macroporous adsorbent resin bed; 3. the effluent liquid of macroporous adsorbent resin bed gets Ephedra sinica fine powder after the concentrating under reduced pressure spraying drying; 4. use the adsorptive on the ethanol elution macroporous adsorbent resin bed; Behind the decompression recycling ethanol, spraying drying gets the byproduct tannin.
2, macropore as claimed in claim 1 village fat legal system is equipped with the new process of production of Ephedra sinica fine powder and byproduct tannin thereof, and it is closely colourless to it is characterized in that the adsorptive on the macroporous adsorbent resin bed is washed to effluent liquid.
