The specific embodiment
Through following specific embodiment the present invention is described further, but does not play restriction.
Experimental example 1The research of ferulaic acid content assay method
(1) instrument and reagent
High performance liquid chromatograph comprises Tianjin, island LC-10AT pump, SPD-10AVP dual pathways UV-detector; Tianjin, island column oven; Zhejiang University's liquid chromatograph work station, ferulic acid reference substance (lot number: 110773-20061108 supplies assay usefulness, Nat'l Pharmaceutical & Biological Products Control Institute) methanol is U.S. Tedia chromatographically pure; Water is ultra-pure water, and other reagent is analytical pure.Drug sample to be measured is a normal open relaxation grain (lot number: 090101 Jiangxi Jimin Kexin Drug Industry Co., Ltd)
2) chromatographic condition is with reference to Radix Angelicae Sinensis medical material assay
Chromatographic column: Penomenex Luna C18 (2) 4.6mm * 150mm column temperature: 30 ℃ of mobile phases: methanol-1% acetum; The detection wavelength is 316nm; Flow velocity: 1.0ml/min
3) selection of detection wavelength
Get the ferulic acid reference substance solution, in 200nm~400nm scope interscan, the result has absorption maximum at the 316nm place, so select 316nm as detecting wavelength.
4) supersound process choice of Solvent: respectively with 50% methanol, methanol as solvent, according to the operation down of assay item, (lot number: content of ferulic acid is measured 090101), and the result sees table 1 to sample.
Table 1 solvent is to measuring result's influence
Therefore, select for use methanol as solvent
5) extraction conditions selection: take by weighing testing sample respectively and carry out supersound process, water-bath reflow treatment, measure all article (lot number: 090101) in content of ferulic acid, the result sees table 2
Table 2 extraction conditions is to measuring result's influence
Therefore, select for use supersound process as extraction conditions.
6) selection of supersound process time: according to the operation down of assay item, the supersound process time was respectively 30,40,50,60,70 minutes, and (lot number does working sample; 090101) content of ferulic acid in, the result sees table 3
The table 3 supersound process time is to measuring result's influence
Therefore, the supersound process time selected for use 60 minutes.
7) blank assay
In the ratio of prescription taste of Chinese medicine, be furnished with the blank preparation that contains the normal open relaxation grain certainly, process blank solution as stated above, measure in accordance with the law, blank solution is not seen apparent chromatographic peak at the place of identical retention time with the ferulic acid reference substance as a result, so think no interference.
8) linear relationship is investigated
Accurate above-mentioned reference substance solution (0.02126mg/ml) 2,4,6,8, the 10ul of drawing injects chromatograph of liquid, measures peak area, is horizontal vertical mark with the sample introduction (ug) of reference substance, is vertical coordinate with the peak area, the drawing standard curve.The result sees table 4
Table 4 linear relationship experimental data (n=5)
Y=300000X+17249
R=0.9992
The result shows: in 0.0424~0.212ug scope, be good linear relationship.
9) stability test
The accurate reference substance solution 10ul that draws, interval certain hour sample introduction, the peak area of mensuration ferulic acid, BSD is: 0.23%, the result shows that the mensuration result is stable in 24 hours, the result sees table 5.
Table 5 stability test data (n=5)
10) precision test
The accurate need testing solution 10ul that draws injects chromatograph of liquid, measures the peak area of ferulic acid, repeats sample introduction 5 times, and RSD is 0.34% as a result, sees table 6
Table 6 precision test data (n=5)
11) repeatability test
According to the operation down of assay item, (lot number: 090101) sample is measured for 5 parts, and trying to achieve relative standard deviation RSD is 0.29%, and the result sees table 7 to same lot number
Table 7 repeatability test data
12) recovery test
Reclaim with application of sample; Precision take by weighing known ferulaic acid content same lot number (lot number: the about 0.5g of the test sample 0901012.61mg/ bag), it is a certain amount of that precision adds ferulic acid reference substance solution (0.206mg/ml) respectively, according to the operation down of assay item; Be calculated as follows the response rate, the result sees table 8
Table 8 average recovery experimental data (n=6)
Average recovery rate is: 98.38%RSD is 0.66%
Experimental example 2,Content of ferulic acid is measured in the normal open relaxation grain
According to the method operation of above-mentioned assay, surveyed content of ferulic acid in 10 batches of normal open relaxation grain grains, the result sees
Table 9
Table 9 normal open relaxation grain content of ferulic acid is measured
Record normal open and relax in the preparation content of ferulic acid all more than the 2.6mg/ bag; Consider the loss error in the industry amplification; Therefore on the basis of minimum content, float downward 20%, therefore obtain examination criteria and be normal open and relax and contain ferulaic acid content in every bag in the preparation and should be not less than 2.0mg.
