The present invention relates to the Chinese medicine extraction method on the medical industry.
Originally produce the technology of the former powder of Crassula argentea Thunb, be to get according to the method for Japan special permission communique 5-19554, lay a good foundation for from natural plants, finding new high protein and efficient blood glucose material, but it is long that this method has run into technological process in process of production, complicated operation, inflammable and explosive ethanol and the petroleum ether of a large amount of uses, the production cost height, problems such as the product poorly water-soluble and the response rate are low, in order to address these problems, in Japan and domesticly carried out a series of further investigation and in production practices, carried out repetition test, proposed to be divided into the new production technology of two classes by chemistry and physical method breaking cell wall.
The characteristics of new technology: 1. cut down inflammable, explosive petroleum ether; 2. reduce alcohol concentration and make it nonflammable in process of production, keep the effect of the broken plant cell wall of ethanol simultaneously from 49%-5%; 3. leaching process is to carry out under room temperature 5-35 ℃, to guarantee the physiologically active of its effective ingredient; 4. simplified with the proteinic operation of 70% alcohol precipitation, kept high protein and trace element and the bioactive substance thereof in the plant; 5. product quality and yield have been improved than old technology.The former powder elaboration of producing with new technology of Crassula argentea Thunb carries out the test of pesticide effectiveness referring to table 3, and is respond well.
1, chemical method breaking cell wall embodiment sees Table the 1-10 example of enumerating in 1.
Embodiment 1 operates by the new technological flow figure of Fig. 1 .49%-5% ethanol breaking cell wall: stem, the leaf of bright Crassula argentea Thunb of 100kg or cajaput are cleaned, placed pulper for example, 49% the medicinal alcohol that adds 50 liters again, soaked 4 hours, high-speed stirred is homogenate, filters.Filtering residue is pressed above-mentioned repetitive operation 3 times with 50 premium on currency respectively, merge 4 times filtrate, be evaporated to behind the recovered alcohol and be thick, put into evaporating pan and be placed on far-infrared oven, dry at 40-50 ℃,, get the former powder of elaboration Crassula argentea Thunb (hereinafter to be referred as the former powder of DSP) 2.4kg with crossing 60 mesh sieves after the pulverizer fragmentation, with the Crassula argentea Thunb fresh weight is that benchmark calculates, yield is 2.4% (original production technology yield: 1.1-2.33%; Average yield is 1.59%).
Embodiment 2-10 gives an example: press the technology of Fig. 1, and operation the same (summary), its alcohol concentration yield is as shown in table 1.

Embodiment 11. filtering residues reclaim to be operated by the recovery artwork of Fig. 2 Crassula argentea Thunb filtering residue for example: the 4.1kg filtering residue is soaked into 50 premium on currency, and 24 hours post-heating to 50 ℃ are cooled to room temperature, filter pressing, and filtering residue is pressed above-mentioned repetitive operation 4 times, merges 5 times filtrate.50-70 ℃ of concentrating under reduced pressure is concentrated into slightly thickly, puts into evaporating pan, is placed in the far-infrared oven again, do 40-50 ℃ of baking, 60 orders of pulverizing, sieve, elaboration 0.05kg, the response rate is 0.05%.
The response rate saw Table shown in 1. embodiment during the filtering residue of embodiment 2-10 reclaimed for example.The filtering residue of embodiment 12. embodiment 2-10 reclaims the same for example (summary)
2, physical method breaking cell wall embodiment:
1. quick-freezing freezing process: operational approach is pressed Fig. 3 quick-freezing speed thawing technique flow operations, quick-freezing speed thaw point scope, and yield sees table 2 for details.
*-5 ℃ refer to quick freezing temperature, about 24 hours of quick-freezing time, thaw and need heat rapidly to 50 ℃.
2. ultrasonic disruption cell wall embodiment
Embodiment: the new technological flow figure by Fig. 4 ultrasound wave breaking cell wall operates, getting the fresh Crassula argentea Thunb of 100kg cleans, add 50 premium on currency, smash to pieces with bruisher and to be homogenate,, filter with ultrasonic stirring 2 hours, repeat aforesaid operations 3 times, merge 4 times filtrate, the filtering residue response rate is 0.08%, the former powder yield 2.56kg of DSP.Yield: 2.56%.Total recovery: 2.64%.
The test of pesticide effectiveness:
1. the former powder hypoglycemic activity of DSP effect observation test: experiment material is the female Wistar rat, body weight 230-260g, and test method sees the special permission communique for details puts down into 5-19554, repeats no more here, and result of the test is as shown in table 3.The former powder of DSP is from example 10 sampling from table of table 1.
Table 3 is respectively organized blood glucose mean variation situation (mg/dl M ± SD)

* with before the administration compare P<0.05 * * P<0.01 △ and compare P<0.05 △ △ P<0.01 with positive control
Check through the t value, compare before each day after positive controls and the administration of glyburide group and the administration and find no statistical significance and difference (P>0.05), and 5g/kg is organized in the 6th day and begins to have significance difference (P<0.05), still has the difference (P<0.01) of highly significant to compare with positive group after the drug withdrawal in 6 days: the 5g/kg group all promptly has remarkable reduction (P<0.05) from the 2nd day beginning blood glucose; The glyburide group also had significant difference (P<0.05) at 2 days and 5 days.
This shows that the former powder of DSP (fresh weight Crassula argentea Thunb extracting solution is dried to powder) acting duration is longer, drug withdrawal still can be kept blood sugar reducing function after 6 days.Thereby its blood sugar reducing function is better than glyburide.
