By table 1 as seen, higher with ethyl acetate, chloroform, water-saturated n-butanol as its extraction yield of solvent.
Embodiment 7.The orthogonal test of extraction conditions.
Three principal elements that influence extraction conditions are solvent and medicinal material ratio (A), extraction time (B) and extraction time (C), and each factor is got three levels (seeing Table 2) and carried out orthogonal test, and experimental technique is as follows:
The level of factor table that table 2 extracts
Figure A20041001406100151
Accurately take by weighing gamboge meal (20 order), every part of about 1 gram is respectively with each orthogonal experiment condition refluxing extraction in 80-90 ℃ of water-bath.After each extraction finished, the extracting solution suction filtration was got filtrate, and the dregs of a decoction (when needing) extract once more by test requirements document, handle with method.After extracting end, with the ethyl acetate 5ml washing dregs of a decoction, merging filtrate and washing lotion, concentrating under reduced pressure reclaims solvent to dried, is washed till in the 25ml volumetric flask, with methanol constant volume with the small amount of methanol gradation.Behind 1000 times of this solution dilutions, by the content assaying method (ZrOCl of this product morellic acid 2Colorimetry), surveying uv-absorbing at the 410nm place, is contrast with the morellic acid methanol solution, calculates the extraction yield of morellic acid.
Calculate the k and the K value of each each level of factor respectively according to each experiment extraction yield.The k1 value of the 1st level is the extraction yield sum that contains three orthogonal experiments of Al, K1=k1/3.According to the K value, calculate the D value of each factor, be example with factor A, D=K Amax-K AminoThe D value is big more, and the influence of this factors on extraction rate is big more.The results are shown in Table 3

From last table as seen, D C>D A>D B, so extraction time is to the having the greatest impact of extraction yield, and three best separately levels of factor are respectively A 2B 2C 3, promptly the ethyl acetate extraction of 6 of medicinal material times of amounts is 3 hours, carries altogether 3 times.
Be the confirmatory experiment of extraction time below.
Because selected extraction time factor (3 times) be the edge level, the result that so carry out confirmatory experiment, the investigation extraction is more than three times (3 times, 4 times, 5 times).
Precision takes by weighing three parts of each 1.0 grams of gamboge meal (20 order), respectively extracts 3 times, 4 times, 5 times with the ethyl acetate of 6 times of amounts, and each three hours, after each extraction finished, the extracting solution suction filtration was got filtrate, and the dregs of a decoction (when needing) extract once more by test requirements document, handle with method.After extracting end, with the ethyl acetate 5ml washing dregs of a decoction, merging filtrate and washing lotion, concentrating under reduced pressure reclaims solvent to dried, is washed till in this 25ml volumetric flask, with methanol constant volume with the small amount of methanol gradation.Behind 1000 times of this solution dilutions, by the content assaying method (ZrOCl of this product morellic acid 2Colorimetry), surveying uv-absorbing at the 410nm place, is contrast with the morellic acid methanol solution, calculates the extraction yield of morellic acid.The results are shown in Table 4.
The proof test of table 4 extraction time
Extraction time sample weighting amount (g) A C (mg/ml) extraction yield (%)
3 times 1.007 0.566 0.0219 54.4
4 times 1.019 0.557 0.0216 53.0
5 times 1.102 0.621 0.0241 54.7
The result shows, extracts can reach the optimum extraction effect 3 times.Therefore, selected extraction time is three times.
In influencing each factor of extraction efficiency, extraction time is a principal element, and the consumption of solvent and extraction time are secondary cause.In process of the test, find that also most effective constituent concentrates in the primary extracting solution.Therefore under the prerequisite that guarantees extraction yield, for cutting down the consumption of energy and the consideration of cost, the solvent load of second and third time is decided to be 3 times, extraction time be 1 hour for best.So best former real extracting method is, reflux extraction extracts 3 times, and solvent load is 12 times of amounts of raw material, and consumption is 6 times of medicinal material for the first time, refluxes 3 hours; The 2nd time and the 3rd consumption are 3 times of amounts of medicinal material, and each refluxed 1 hour.
Embodiment 8.The investigation of separation and purification condition.
1, select for use basic solution to separate the foundation of utmost point morellic acid.
Morellic acid is a ketone compounds, contains carboxyl in the structure, and acidity is stronger relatively, can be dissolved in 5%NaOH solution, 5%Na 2CO 3Solution, 5%NaHCO 3Solution and 5%Ca (OH) 2In the solution.And other the main ketone compounds in the gamboge does not contain carboxyl, and 1-2 phenolic hydroxyl group only arranged, and 6 phenolic hydroxyl groups and 8 carbonyls formation intramolecular hydrogen bonds, and acidity is less relatively, can not be dissolved in above-mentioned inorganic alkaline solution, they can be separated whereby.
2, select the salifiable foundation of organic bases for use.
Morellic acid and neogambogic acid are the arborescens organic compound, only depend on solvent extraction method can not reach and other compound separation purpose.In experimentation, NaOH, Na have been investigated 2CO 3, NaHCO 3, alkaline reagentss such as diethylamine, triethylamine, pyridine, organic basess such as diethylamine, triethylamine, pyridine can generate the crystallization of stable salt in mutually at organic solvent with them, so selected organic bases for use in this technology.
It is 3, selected that ether-organic bases-sherwood oil is the foundation of recrystallisation solvent
Because morellic acid solubleness in the ether of heat is bigger, and solubleness is little when cold.This technology adds a small amount of organic bases in ether-sherwood oil, can make its salify crystallization on the one hand, has reached the purpose of purifying, compares with document on the other hand, has reduced the consumption of organic bases such as triethylamine, pyridine, diethylamine in a large number.
4, the investigation of ether or acetone consumption in the step (3).
With the ether is example, has investigated the ether dissolution morellic acid crude extract of 1 times, 1.5 times, 2 times, 2.5 times, 3 times and 5 times amount respectively.When consumption is lower than 2.5 times, be difficult to dissolve fully, be higher than 3 times and all can dissolve fully, so the consumption of selected ether is 3 times of morellic acid.
5, the investigation of step (3) PetroChina Company Limited. ether consumption.
Investigated 1/10,1/5,1/4,1/2 of ether or acetone respectively, the sherwood oil consumption of 1 times of volume influences crystalline.Get each 1g of morellic acid pyridinium salt crude product, use the 10ml ether dissolution, and add 1,1.5,2,2.5,5 and the sherwood oil mixing of 10ml respectively, room temperature was placed three hours, suction filtration, and it is dry under infrared lamp to get solid, weighs, and calculates yield.Crystallization sees Table 5.
With when 1/4 times of consumption, all can in a few hours, separate out solid during 1/2 times of volume, eduction rate does not have notable difference; When being 1/10,1/5 times of volume, solid generates very slow, and eduction rate is lower in the time of three hours; Yet, when consumption is 1 times, but can not separate out solid, only at the bottom of bottle, have one deck oily matter.The 1/4-1/2 that therefore selected sherwood oil consumption is ether or acetone doubly.
The investigation of table 5 sherwood oil consumption
The sherwood oil consumption 1/10 times 1/5 times 1/4 times 1/2 times 1 times
Phenomenon is described Crystallization speed is slower Crystallization Can not crystallization
Yield (%) ??21.1????37.9 ??56.2????54.7
