The method for building up of the high-pressure liquid phase finger-print of evodia rutaecarpa and extract thereof
Technical field
The present invention relates to the method for building up of Yuqing, a kind of Guizhou GAP evodia rutaecarpa medicinal material and extractive HPLC (high performance liquid chromatography) finger-print thereof, and the evodia rutaecarpa medicinal material and the extractive HPLC standard finger-print thereof of gained thus, the Pharmaceutical Analysis technical field belonged to.
Background technology
Evodia rutaecarpa is rutaceae evodia rutaecarpa Evodia rutaecarpa (Juss.) Benth., Shi Hu Evodiarutaecarpa (Juss.) Benth.var.officinalis (Dode) Huang or the dry almost ripe fruit of dredging hair evodia rutaecarpa Evodiarutaecarpa (Juss.) Benth.var.bodinieri (Dode) Huang.Beginning is stated from Shennong's Herbal, main product in Guizhou, Hunan, Chongqing, Jiangxi, zhejiang and other places.Evodia rutaecarpa is famous genunie medicinal materials in Guizhou Province and seedling medicine commonly used, accounts for more than 30% of national total production, and the Yuqing, Guizhou has been carried out extensive artificial growth, and succeeded by GAP standardization requirement.
Traditional medicinal material and extract evaluation index thereof have significant limitation." only control the quality of evodia rutaecarpa under Chinese pharmacopoeia (version was an one in 2010) the evodia rutaecarpa item with total alkali in the evodia rutaecarpa medicinal material and limonin content, fail to reflect more all sidedly the situation of other compositions in evodia rutaecarpa and the extract thereof, traditional Chinese medicine fingerprint provides solution for this problem.
At present, existing evodia rutaecarpa liposoluble, water-soluble fingerprint technology (publication number: CN1932506A, CN1932507A) research, but fat-soluble, water-soluble portion research that this fingerprint pattern technology has only been done respectively, and the characteristic peak negligible amounts does not still have the investigative technique that comprehensively reflects full composition of GAP base, Yuqing, Guizhou evodia rutaecarpa and evodia extract finger-print in known technology.At the existing deficiency of present evodia rutaecarpa fingerprint pattern technology, the present invention studies evodia rutaecarpa medicinal material and extract finger-print thereof with the HPLC linear gradient elution method, select for use the more common two kinds of pseudo-product (Chinese prickly ash, Coriaria sinica) of evodia rutaecarpa to finish the check of finger-print applicability first, the finger-print of being set up has been integrated evodia rutaecarpa water-soluble composition and liposoluble constituent, can embody the overall chemical information of evodia rutaecarpa medicinal material and extract thereof more all sidedly; The degree of separation and the peak shape at the total peak of evodia rutaecarpa medicinal material of setting up and extractive HPLC fingerprint thereof are better; This finger-print has been included water-soluble portion and fat-soluble part in evodia rutaecarpa medicinal material and the extract thereof in addition, good reproducibility, workable, meet finger-print and detect requirement, for the quality control and the real and fake discrimination of evodia rutaecarpa medicinal material and extract thereof provides a kind of new method.
