The record crocin has effect promoting blood circulation and removing blood stasis, as to scatter knot in the prior art; Be used for apoplexy syndrome of blood stasis (brain vessle-Bi symptom-complex plug) etc.
The finger-print experimental technique of prior art is to test according to the high performance liquid chromatography of an appendix VID of Chinese Pharmacopoeia version in 2000 defined to carry out, but the high performance liquid chromatography of an appendix VID of Chinese Pharmacopoeia version in 2000 defined is a general rule, not to that concrete kind descriptive analysis method.
General provision is:
1, chromatographic condition and system suitability test
Make filling agent with reverse-phase chromatographic column; Organic phase-buffer solution is moving phase, the moving phase processing of should filtering, outgas, and the detection wavelength is 440nm.It is 2.8-3.3 minute that the adjustment flow velocity makes the retention time at crocin-1 peak, and number of theoretical plate calculates with crocin-1 peak should be not less than 1500.
2, the peak at the total peak of technical parameter number and relative retention time: 1 (0.67-0.72): 2 (0.80-0.85); 3 (S is with reference to peak-crocins-11.0), 4 (1.1-1.2), 5 (crocin-21.4-1.6), 6 (crocin-42.4-2.6), 7 (crocin-36.4-7.0), 8 (7.4-8.1).Peak area ratio: 5: S=(0.40-0.75).
3, the about 5mg of crocin-1 reference substance is got in the preparation of object of reference solution, accurate claims surely, puts in the measuring bottle of 25ml, with dissolve with methanol and be diluted to scale, shakes up.Precision is measured above-mentioned crocin-1 reference substance solution 2.0ml and is put in the 25ml measuring bottle, adds moving phase and is diluted to scale, shakes up, and promptly gets object of reference solution.
4, the preparation of need testing solution
The west safflower medicinal material is got the about 20mg of the dried fine powder of this product, puts in the apparatus,Soxhlet's, adds methyl alcohol 50ml, and reflux is to extracting liquid colourless, put coldly, use the methanol wash extraction apparatus, merge extract and cleansing solution and put in the 100ml measuring bottle, add moving phase and be diluted to scale, shake up, promptly.Crocin is got the about 20mg of this product, puts in the measuring bottle of 25ml, with dissolve with methanol and be diluted to scale, shakes up.Get this liquid 1.0ml and put in the 25ml measuring bottle, add moving phase and be diluted to scale, shake up, promptly.
The injection crocin is got 2 bottles of this product, with moving phase dissolving and be diluted in the measuring bottle of putting 50ml.Get this liquid 1.0ml and put in the 50ml measuring bottle, add moving phase and be diluted to scale, shake up, promptly.
5, accurate respectively above-mentioned object of reference solution and each 10ul of need testing solution of drawing of determination method, inject liquid chromatograph respectively, write down 1 hour chromatogram, calculate the retention time and the peak area of each chromatographic peak, the peak at the total peak of contrast number and relative retention time should be up to specification.
According to the technical requirement of State Food and Drug Administration to the research of traditional Chinese medicine finger-print, when the finger-print of crocin and medicinal material and injection has been carried out analysis, owing to there is the carboxylic acid (seeing following formula) of a part in crocin-3 molecular structure, in organic phase-water, can ionization go out H
+Or and H
+In conjunction with forming carboxylic acid, this mobile equilibrium is unsettled, therefore causes crocin-3 when fingerprint map analyzing, and the retention time of each sample introduction is unsettled, and drift is indefinite, and repeatability is very poor, does not meet the requirement of fingerprint map analyzing.
Summary of the invention
In order to overcome the deficiencies in the prior art part, the object of the present invention is to provide the fingerprint analysis method of a kind of improved Chinese medicine and extract thereof, particularly crocin is carried out the method for fingerprint map analyzing.
In order to finish above-mentioned goal of the invention, the present invention by the following technical solutions:
The analytical approach of the finger-print of a kind of Chinese medicine crocin composition and extract thereof comprises and adopts chromatographic column or reverse-phase chromatographic column high performance liquid chromatography, and organic phase-buffer solution is moving phase, it is characterized in that:
The filler of chromatographic column is selected from C1, C3, C6, C8, C18, CN, NH
2, described organic phase-buffer solution is organic phase-salt or the acids buffer solution of pH value for 1.5-8.5, and wherein the volume ratio of organic phase is 5%-80%, and preferably the volume ratio of organic phase is 10%-60%.
Described organic phase comprises tetrahydrofuran, methyl alcohol, acetonitrile.
The preferred pH value of described organic phase-buffer solution is 2.8-8.0.
Analytical approach of the present invention is to find employing organic phase-buffer solution to make moving phase, for the analytical approach of the finger-print of west safflower glycoside Chinese medicine that contains carboxylic acid structure and extract thereof.The filler of chromatographic column that concrete is is selected from C1, C3, C6, C8, C18, CN, NH
2, moving phase consist of organic phase-buffer solution, pH value wherein is 1.5-8.5, the ratio of organic phase is 5%-80% (v/v), the ratio of buffer solution is 20%-80% (v/v).
What the present invention adopted is that organic phase-buffer solution is moving phase.If not adopting organic phase-buffer solution is moving phase, be moving phase and adopt organic phase-water, then contain the crocin-3 of carboxylic acid, when analyzing is unsettled, and it is unsettled therefore causing each retention time, and drift is indefinite, poor repeatability does not meet the requirement of fingerprint map analyzing.
The present invention's (concentration of salt is that 0.005mol/L-0.2mol/L, pH value of buffer solution scope are 2.0-8.0) when in aqueous solution, adding various salts with corresponding acid or polyprotonic acid formation buffer solution, the retention time of crocin-3 is stable, the retention time of crocin-1, crocin-2, crocin-4 is constant substantially, the stable in properties of compound meets the requirement of fingerprint map analyzing.
Principal ingredient is a crocin-1 in the specimen of the present invention, its stable in properties, and relative content is elected object of reference as more than 50%.
