The preliminary screening of 2.3 African Ghana seed extract extracting methods
Precision weighs 0.5g10 parts of African Ghana's seed (crossing 50 meshes), is placed in boiling flask, each that 50% ethyl alcohol is added
50mL, weighed quality, wherein 5 parts of samples distinguish heating and refluxing extraction 0.5,1,1.5,2,2.5h, ultrasound mentions another 5 parts of samples respectively
Take 10,30,50,70,90min.Standing is extracted to room temperature, weighed to supply quality, 0.22 μm of filtering with microporous membrane takes continuous filter
Liquid, sample detection.The list for selecting 11 shared peaks of S/N > 20 in chromatogram as evaluation index, and being handled with ultrasonic 30min
Position crude drug peak area be 100%, calculate different disposal sample shared peak peak area recovery rate, be compared, by with compare
Product map corresponds to retention time can initial guess;Comprehensively consider the factors such as chemical composition stability, operation convenience, selection ultrasound
Method is the extracting method of African Ghana seed extract.
The process flow of 2.4 African Ghana seed extract ultrasonic extractions
Negated continent Ghana seed crushes, and crosses 50 meshes, and precision is weighed in right amount, set in boiling flask, and the second of respective concentration is added
Appropriate alcohol, weighed, ultrasonic extraction (40kHz, 150W) are taken out and are stood to room temperature, it is weighed supply quality to get.
The single factor experiment of 2.5 African Ghana seed extract ultrasonic extraction process parameters
Using 11 of S/N > 20 in chromatogram shared peak total peak areas as evaluation index, different ultrasounds is investigated respectively and is mentioned
Take time (10,20,30,40,50min), concentration of alcohol (20%, 35%, 50%, 65%, 80%) and liquid-to-solid ratio (50: 1,100
: 1,250: 1,500: 1,800: 1mLg-1) influence to African Ghana's seed extract extraction efficiency.
2.5.1 influence fixer of the ultrasonic extraction time to extraction effect
Material is than being 100: 1 (mLg- 1), concentration of alcohol 50%, selection ultrasound 10,20,30,40,50min is tried
It tests, as a result sees Fig. 2.With the extension of ultrasonic time, shared peak total peak area is gradually increased;But after ultrasound 20min, it is total to share peak
Peak area tends to be steady, and extraction tends to be complete.To prevent ultrasonic time too long, Extracting temperature is caused to increase, African Ghana's seed mentions
It takes effective component in object to degrade, therefore selects 20min for optimal ultrasonic time.
2.5.2 the fixed liquid-to-solid ratio of influence of the concentration of alcohol to extraction effect is 100: 1 (mLg-1), and ultrasonic time is
20min selects 20%, 35%, 50%, 65%, and 80% concentration of alcohol extracts test to African Ghana's seed extract, as a result
See Fig. 3.When concentration of alcohol is 65%, the total peak area at shared peak reaches peak value;When concentration of alcohol is 80%, extraction effect
Weakened again, therefore is selected 65% for optimal concentration of alcohol.
2.5.3 influence of the liquid-to-solid ratio to extraction effect
Fixed ultrasonic time is 20min, concentration of alcohol 50%, selects liquid-to-solid ratio 50: 1,100: 1,250: 1,500: 1,
800∶1(mL·g- 1) tested, as a result see Fig. 4.With the increase of liquid-to-solid ratio, the total peak area at shared peak is gradually increased, because
Constantly increase for Extraction solvent volume, the contact surface of medicinal powder and solvent molecule also constantly increases, and extracted amount is caused constantly to increase
It is more.When liquid-to-solid ratio is greater than 100: 1 (mLg- 1), the growth trend of shared peak total peak area slows down, and extraction tends to be complete;But it considers
Being significantly increased for liquid-to-solid ratio may generate certain influence to extracting solution pH, make sensitive to pH value in African Ghana's seed extract
The content of material such as aromatic acid change, therefore select 100: 1 (mLg- 1) it is more excellent liquid-to-solid ratio.
2.6 response phase methods optimize African Ghana's seed extract ultrasonic extraction process test
On the basis of single factor experiment, the level value of 3 liquid-to-solid ratio, concentration of alcohol and ultrasonic time factors is determined, use
Design-Expert8.0.6 software carries out the design of Box-Behnken response surface and data analysis.Specific experiment factor and each water
Level values are shown in Table 1.
1 response surface experiments factor of table and level
According to the Combination Design principle of Box-Behnken, using 3 factor of De-sign-Expert8.0.6 software design, 3 water
Totally 15 experiments are put down, wherein central point 3 repeated experiments;The total peak area at peak is shared as response using S/N > 20 in chromatogram
(R), specific experiment design scheme and 2 be the results are shown in Table.
2 response surface experimental result of table
Variance analysis and quadratic polynomial regression fit are carried out to experimental data using Design-Expert8.0.6 software,
Regression model P is 0.0032, illustrates that model is extremely significant;Losing quasi- item P is 0.2360, not significantly;The coefficient of determination is 0.9677, explanation
The models fitting degree is good;Factor A, B, B2, C2 is to significantly affect factor, is illustrated to African Ghana's seed extract extraction effect
It is affected.For reduced equation, model is optimized manually, on the basis of original fit equation, remove not significant item BC with
After A2, the results of analysis of variance is shown in Table 3, optimizes resulting actual value equation:
R=2.2806 × 107+7.8125×104A+4.7447×108B+1.5284×108C-1.3857 × 103AB-
1.6157×103AC-3.1633 × 104B2-3.0159 × 104C2。
Analysis of variance table after table 3 optimizes
。
Response surface curved surface can more intuitively reflect each factor and influence of the reciprocation of factor to response two-by-two.Africa
In the contour map and response surface 3D map of Ghana's seed extract ultrasonic extraction.Concentration of alcohol extracts African Ghana's seed extract
Influential effect is maximum, followed by liquid-to-solid ratio, and influence of the ultrasonic time to African Ghana's seed extract extraction effect is minimum.Liquid-to-solid ratio
It is affected with the reciprocation of concentration of alcohol to African Ghana's seed extract extraction effect, is secondly liquid-to-solid ratio and ultrasonic time
Reciprocation, the reciprocation of concentration of alcohol and ultrasonic time is least significant.
With the resulting African Ghana seed extract ultrasonic extraction optimised process of Design-Expert 8.0.6 software optimization
Are as follows: liquid-to-solid ratio 53.38mLg- 1, concentration of alcohol 72.04%, ultrasonic time 20.06min, with this condition share the face peak Zong Feng
Long-pending predicted value is 2.160 8 × 108。
2.7 verification test
For the reliability of auth response face method acquired results, the process conditions of model optimization are verified.In view of reality
The feasibility and convenience tested select technological parameter: solid-liquid ratio 53mLg- 1, concentration of alcohol 72%, ultrasonic time 20min into
Row experiment 3 times, the results are shown in Table 4, illustrate equation and the fitting of actual experimental situation preferably, the process of optimization, feasible.Compare
Each the mentioning by contained content assaying method and Optimized Extraction Process of African Ghana's seed extract in " Chinese Pharmacopoeia " (version in 2010)
Take effect.Test solution 3 is prepared by CP method (liquid-to-solid ratio 500mLg-1, concentration of alcohol 50%, ultrasonic time 30min)
Part, sample detection records chromatogram, is compared with confirmatory experiment result.As a result, it has been found that: it is resulting that response phase method optimizes technique
Shared peak total peak area is high compared with CP method by 10.84%;The resulting African Ghana's seed extract peak area of response surface optimization technique compared with
CP method low 1.30%, no significant difference, and liquid material is bigger in CP method lead in extracting solution each ingredient response relatively
Low, peak number is less in chromatogram.Therefore, from the point of view of African Ghana's seed extract quality thoroughly evaluating, response phase method optimization
Resulting Africa Ghana seed extract ultrasonic extraction process has more advantage compared with pharmacopeia extraction method.
