1The extraction rate of transform.
Experimental example 2: macroporous adsorbent resin technical study
Method 1: get the Radix Panacis Quinquefolii of the following long shoot of Jilin, place of production 5g, grind and be powder, cross 100 mesh sieves, and detect ginsenoside Rb1's content.Respectively get 50g, be numbered respectively 2-1 and 2-2 number.Get the 2-1 powder, behind the water logging bubble 15min with 10 times of normal temperature, (ultrasonic wave medicine handler " the 4th generation " frequency 26KHz, 47KHz, 70KHz Jining Sinobest Electronics Co., Ltd. produce with ultrasonic wave, extract 3 times down together), extract frequency 26KHz, each 30 minutes, filter merging filtrate; (model: D-101 is product type lot number only: 070305 product standard: Tianjin Q, HG3790-91 Tianjin sea light chemical industry company limited produce filtrate by 1.5 times of amount macroporous adsorbent resins, down together), after absorption finishes, wash with water to colourless, use 70% ethanol elution of 4 times of amount of resin again, elutriant reclaims ethanol, concentrates, drying under reduced pressure gets the total panaquilon extract 2-1 number.
Method 2: other gets the 2-2 powder, behind the water logging bubble 15min with 10 times of normal temperature, uses ultrasonic extraction 3 times, extracts frequency 26KHz, each 30 minutes, filters merging filtrate; Filtrate is by 1.5 times of amount macroporous adsorbent resins, after absorption finishes, wash with water to colourless, be washed till in addition colourlessly, and wash with water, use 70% ethanol elution of 4 times of amount of resin at last to neutrality with 0.5% NaOH solution, elutriant reclaims ethanol, concentrate, drying under reduced pressure gets the total panaquilon extract 2-2 number.More than experiment repeats 3 times, gets mean number 3 times.Ginsenoside Rb1's content (%) the results are shown in Table 2 after testing.
Table 2 compares with the technology of not washing adsorption column with the solution washing adsorption column of the inorganic salt that contain alkalescence
Experimental example 3: simulated moving bed chromatography technology is separation and purification ginsenoside Rb from the American ginseng total saponins extract
1Monomeric
From the total panaquilon extract, separating purified ginsenoside Rb
1In the monomeric technological process, what we adopted is simulated moving bed chromatography, and vacuum concentration evaporate to dryness and recrystallizing technology obtain ginsenoside Rb
1Monomeric.This technology has the separation efficiency height, and easily technology is amplified, the advantage of clean environmental protection.
Since simulated moving bed system be one non-linear, nonideal many-degrees of freedom system, the purity of product and yield depend on the parameter optimization of this nonlinear many-degrees of freedom system and selection.Below be optimization and selection to several important parameters
1. the selection of proportion of mobile phase
The selection of table 3 proportion of mobile phase
As seen from Table 3, when the methyl alcohol volume fraction is hanged down, ginsenoside Rb
1Yield is very low, and when the methyl alcohol volume fraction was high, separating power was poor, ginsenoside Rb when V (methyl alcohol): V (water)=45: 55
1Yield is the highest, so proportion of mobile phase is decided to be 45: 55.
2. the selection of ginsenoside mass concentration in the sample introduction
The selection of ginsenoside mass concentration in table 4 sample introduction
Rb when as seen from Table 4, the ginsenoside mass concentration is 0.2g/ml in the sample introduction
1Yield is the highest, so it is chosen as ginsenoside mass concentration in the sample introduction.
3. the selection of switching time
The selection of table 5 switching time
As seen from Table 5, switching time is too short, and the flushing of preceding impurity is not enough, is brought in the product and reduces ginsenoside Rb
1Purity.Switching time is oversize, again can be with ginsenoside Rb
1In the impurity, make ginsenoside Rb in the effluent before bringing into
1Purity drop, rear impurity increases.When be 6min switching time, ginsenoside Rb
1Purity the highest, and its yield is not subjected to obviously to influence, so will be chosen to be about 6min switching time.
4. the selection of elution flow rate
The selection of table 6 elution flow rate
As seen from Table 6, when elution flow rate was low, fast component flushing degree was not enough, brings impurity in the product into, has influenced ginsenoside Rb
1Yield.Elution flow rate is excessive, part ginsenoside Rb
1Can flow out from the impurity outlet, make ginsenoside Rb
1Yield and purity all be affected.When elution flow rate is 60ml/min, ginsenoside Rb
1Yield the highest, so the regulation elution flow rate is 60ml/min.
Following embodiment all can realize the effect of above-mentioned experimental example.
