The investigation of embodiment 3 spray coagulation parameters
[screening of poor solvent kind]
In theory, as long as can change the polarity of extractum and all can not realize preparation technology of the present invention with the solvent of water formation azeotropic mixture.But consider that solvent exists potential safety hazard, toxicity etc. when pilot scale and big production, investigated three kinds of solvents that allow use in the Chinese medicine preparation large-scale production process: the influence to testing of ethanol, ethyl acetate and n-butyl alcohol.
In the experiment with the preparation " BAZHEN KELI " be example, poor solvent is investigated:
Get a step gained eight delicacies extractum among 1/5 embodiment 1 that writes out a prescription, relative density 1.18 (60 ℃) sprays into respectively in 4 times of ethanol, ethyl acetate and n-butyl alcohol, investigates and separates out the dry weight of solid content, dried cream amount and both sums of supernatant after spray is coagulated.The results are shown in Table 1:
Table 1
As seen from the above table, the eight delicacies extractum of equivalent sprays in three kinds of solvents, and total solid content is had no significant effect.Experimental selection ethanol is that cost is also minimum because ethanol uses the most extensively, the safest in commercial production, and is also minimum to the influence of workman's health, and therefore, we unify to have selected ethanol for use in experimentation is solvent.
[ethanol adds the screening of parameter]
By " screening of poor solvent kind " result as can be known, poor solvent of the present invention is good with ethanol, therefore, is example with preparation " BAZHEN KELI ", and the spray coagulation parameter is done further screening.
Back solid content weight serves as to investigate index to spray with fixed attention, because the solid content that forms after the spray with fixed attention is many more, solid content residual in the supernatant is just few more, concentrates and carries out with regard to easy more, and follow-up granulation is with regard to easy more success.Adopt L
9(3
4) orthogonal table arranges the level of concentration of alcohol, ethanol consumption and time of repose, inquire into.Factor level table such as table 2:
Table 2: factor level table
The mensuration of total solid weight: use L
9(3
4) orthogonal table arrangement test, take by weighing the extractum that standard prescription 1/10 is measured, spray by the setting scheme and coagulate, the dry weight of separating out solid content after coagulating with spray is an evaluation index.The results are shown in Table 3, table 4.
Table 3: back solid content orthogonal test table and range analysis result are coagulated in spray
Table 4: back solid content orthogonal test analysis of variance table is coagulated in spray
*P<0.05
As shown in Table 2, extractum is sprayed in the 50-95% ethanol of 4-10 times of extractum weight and leave standstill 0.5-1.5h, can from extractum, isolate and be insoluble to alcoholic acid effective ingredient in a large number, reduce the paste-forming rate of extractum significantly.By range analysis and The results of analysis of variance as can be known, the A factor is the significance influence factor (P=0.0287<0.05) of this experiment, and the A value is the bigger the better, and therefore, the optimum level of determining the A factor is 95%.B, C factor do not have the significance influence to experimental result, and actual in conjunction with producing, the ethanol consumption is defined as 4 times, and time of repose is defined as 30min, and therefore, the best experimental program that filters out is A

3, promptly the ethanol with 4 times of amounts 95% leaves standstill 30min.
[ethanol adds the checking of parameter] is used for preparation " Dioscorea nipponica bony spur tablet " with above-mentioned ethanol adding method, coagulates the production needs whether technology can satisfy different prescription drugs with checking the present invention spray.
Dioscorea nipponica bony spur tablet extractum with 1/5 prescription sprays in 1 times, 2 times, 3 times, 4 times, 5 times, 6 times 95% ethanol respectively, leaves standstill 30 minutes, separates out the dry weight of solid content after coagulating with spray, dried cream amount and both sums of supernatant is that evaluation index is estimated.Result of the test such as table 5:
Table 5
As seen from the above table, when the consumption of etoh solvent reaches 4 times, the dry weight substantially constant of the solid content that spray is separated out after coagulating has guaranteed the precipitation molding of most of active ingredient, and has been beneficial to the carrying out of follow-up granulation, when the ethanol consumption more after a little while, form semi-solid less coagulated in spray, and the extractum after the supernatant concentration is more, is unfavorable for pelletizing forming, consider from the angle of energy savings, in experimentation, selected for use 4 times of solvents as optimal dose.
In each parameter that spray is coagulated, the relative density of extractum is not the major influence factors of experiment, and the pharmacy relative density is controlled at 1.20 with interior (60 ℃), all can guarantee good flowability, and spray is carried out with fixed attention smoothly.
According to above result of the test as can be known, Chinese traditional medicine water extract is sprayed into 95% ethanol of 4 times of weight or volumes, leave standstill 30 minutes after, can greatly reduce the paste-forming rate in the extracting solution, consider production cost and to the influence of later stage preparation, preferred 4 times of amount 95% ethanol; When spraying into the water extract, can adopt the sprayer unit of present commercially available routine, atomisation pressure is controlled at more than the 0.2MPa, fogdrop diameter is controlled at 200-500 μ m, all can reach good technical effect.
