Abstract
The present invention provides a technological process for extracting effective components from a medicinal plant, which comprises: pulverizing the raw medicinal plant material, screening the powder with an 80-mesh sieve, soaking the fine powder in distilled water, vibrating the solution with ultrasonic sound, centrifugally removing residues, controlling temperature below 40 DEG C, distilling under reduced pressure, precipitating with alcohol, taking supernatant fluid, controlling temperature below 40 DEG C, distilling under reduced pressure, recovering alcohol and drying by freezing so as to prevent the effective components of the medicinal plant from being influenced by heating in the whole extraction process. Thus, the therapeutic effect of effective ingredients which are easily damaged by heating is guaranteed.
Description
The present invention relates to a kind of active principle from plant medicine process for extracting, particularly plant amedica and exempt from the process of extraction under the heating condition.
Existing plant amedica is extracted main employing decocting and concentrating, precipitate with ethanol, is added thermal distillation recovery ethanol, there is following defective in this process: some active ingredient long-time heating is destroyed, some medicine is difficult for dissolving and extracts not exclusively with general decocting time in water, some contains the volatility active ingredient and adopts the method for decoction to make the volatile component mistake of escaping in a large number.
The present invention is directed to the scarce limit of existing technology and adopted the fine powder dipping, ultrasonic wave concussion, centrifugally take off slag, control temperature distilling under reduced pressure concentrates under 40 degrees centigrade the condition being no more than, alcohol taking the pulse heavily supernatant control temperature reclaims ethanol being no more than under 40 degrees centigrade the condition, lyophilization, whole technical process exempt from heating, avoided plant amedica to be heated going to pot and affect the treatment.
The object of the present invention is achieved like this: with plant drug material crushing screening 80 orders, the adding distil water dipping, use ultrasonic wave concussion during dipping simultaneously, impel active ingredient to precipitate in the solution, then adopt the centrifugal slag that takes off to obtain medicinal liquid, place vacuum equipment to be decompressed to the medicinal liquid that obtains and make water explosive evaporation when being no more than 40 degrees centigrade, the moisture content of evaporation with vacuum equipment extract discharge concentrated solution, concentrated solution is added the heavy partial impurities of going of ethanol alcohol get supernatant, again its supernatant is put be decompressed to ethanol in the vacuum equipment can explosive evaporation when being no more than 40 degrees centigrade, the ethanol of evaporation is recovered to such an extent that thing is got in proposition, lyophilization must be extracted dry powder again, whole technical process need not heating, the influence that the active ingredient of the destructible of having avoided being heated is heated.
The present invention realizes by this technological process operation.
Fig. 1 is a process chart of the present invention.
Claims (1)
1, a kind of active ingredient of autonomic drug heating free method for extracting, it is characterized in that: form: plant drug material crushing screening 80 orders by the following step, the adding distil water dipping, ultrasonic wave concussion, the centrifugal slag that takes off, temperature control are no more than 40 degrees centigrade of distilling under reduced pressure, precipitate with ethanol, temperature control is no more than 40 degrees centigrade of distilling under reduced pressure and reclaims ethanol, lyophilization.
