And the analysis condition of composition to be measured is determined, the peak at composition retention time to be measured is found, to integrating peak areas, its peak area is one
Determine in scope and its content has good linear relationship, and be used to quantitative determine.
The present invention innovative point and have the beneficial effect that:
(1) use ultra performance liquid chromatography-mass spectrometry, by A phases of acetonitrile, 0.12% acetic acid/1mmol/L ammonium acetates be
B phases, through 4 transformation of scale gradient elutions, flow velocity 0.8mL/min;40 DEG C of column temperature;The scanning side of (MRM) is monitored with multiple reaction
Negative ions are monitored simultaneously under formula, and ion gun is ESI sources, and atomization gas (GS1, N2) aids in gas (GS2, N2), whole process uses nitrogen
Gas, collision atmospheric pressure is medium, Q1 and Q3 resolution ratio is UNIT;Determine evodia rutaecarpa granule Content of Chlorogenic Acid, coffee
Acid, rutin, Hyperoside, aurantiamarin, dehydroevodiamine, limonin, rutaecarpin, Rutaecarpine and evodia rutaecarpa card product
Alkali content, 10 kinds of compositions detection in 22 minutes is finished, and method is easy, quick, accurate, noiseless.To report first.
(2) ultra performance liquid chromatography-mass spectrometry is compared with general high performance liquid chromatography, with high sensitivity, Gao Xuan
The characteristics of selecting property, high accuracy, 10 kinds of compositions are determined in 22 minutes and finished.No longer by heterogeneity best detection wavelength it is different,
Content height it is different, polarity spectrum great disparity puzzlement, test limit can by efficient liquid phase g grades of μ, be reduced to ng grades, significantly
Expand detection range.The assay collection of illustrative plates of 7 kinds of compositions is learnt in above-mentioned evodia rutaecarpa, and the short time is difficult on liquid chromatograph
With the micro constitutent for separating or quantitative determining, it is combined by liquid phase mass spectrograph, obtains good separation, obtaining can accurate quantitative analysis survey
Fixed crest information.
(3) rutin, Hyperoside, aurantiamarin belong to flavones ingredient, and caffeic acid and chlorogenic acid are organic acid, and lemon is bitter
Element is limonin, and rutaecarpin, Rutaecarpine, dehydroevodiamine and evocarpine are alkaloids, this
A little Components Chemical structures are as follows:
Learnt by structure chart, structure is different, polarity spectrum great disparity, by the big minispread of polarity, it goes out on liquid phase mass spectrograph
The order at peak is:Chlorogenic acid → caffeic acid → rutin → Hyperoside → aurantiamarin → dehydroevodiamine → limonin → Wu
Fruit of medicinal cornel alkali → Rutaecarpine → evocarpine, using general efficient liquid phase, it is difficult to which it is good to obtain separation in a short time
Good crest;Best detection wavelength and it is different, it is difficult to unified;Content height is different, has some in liquid phase without crest information;Institute
To use common efficient liquid phase, it is impossible within 22 minutes, different structure, polarity great disparity, content height difference more than 700 are determined
10 kinds of compositions again.And ultra performance liquid chromatography mass spectrometry is used, succeed detection.For many fingers of evodia rutaecarpa granule
Mark quick detection and provide method.
