Description
Technical field
The present invention relates to quality control technologies for traditional Chinese medicine field, particularly relate to a kind of spina date seed reference extract and its preparation method and application.
Background technology
Spina date seed, another name jujube nucleus, mountain jujube kernel.It is the dry mature seed of Rhamnaceae plant wild jujube.To gather ripening fruits in the time of the year when autumn changes into winter, removing pulp and nucleocapsid, collect seed, dry and form.It is born in endroit, roadside, mainly originates in the ground such as Henan, Hebei, Shaanxi, Liaoning, Shanxi, Shandong, Yunnan.Gather during fruit maturation in autumn, remove pulp and stone, get seed, life is used or micro-stir-fry is used.
Spina date seed, as a kind of Chinese crude drug, records in Chinese Pharmacopoeia.Chinese Pharmacopoeia carries out indentification by TLC to the saponins of spina date seed medicinal material and flavones ingredient respectively: wherein, the thin-layer identification method of saponin component is: get this product powder 1g, add methyl alcohol 30ml, add hot reflux 1 hour, filter, filtrate evaporate to dryness, residue adds methyl alcohol 0.5ml makes dissolving, as need testing solution.Separately get Saponin A, B reference substance, add methyl alcohol respectively and make every 1ml respectively containing the mixed solution of 1mg, product solution in contrast.According to thin-layered chromatography (annex VI B) test, draw each 5 μ l of above-mentioned two kinds of solution, put respectively on same silica gel g thin-layer plate, with water saturated normal butyl alcohol for developping agent, launch, take out, dry, spray with 1% vanillin-sulfuric acid solution, inspect immediately.In test sample chromatogram, on the position corresponding to reference substance chromatogram, the spot of aobvious same color.The thin-layer identification method of flavones ingredient is: get this product powder 1g, add sherwood oil (60 ~ 90 DEG C) 30ml, add hot reflux 2 hours, filter, discard sherwood oil liquid, the dregs of a decoction volatilize, and add methyl alcohol 30ml, add hot reflux 1 hour, filter, filtrate evaporate to dryness, residue adds methyl alcohol 2ml makes dissolving, as need testing solution.Separately get spina date seed control medicinal material 1g, be made in the same way of control medicinal material solution.Get spinosin reference substance again, add methyl alcohol and make the solution of every 1ml containing 0.5mg, product solution in contrast.Test according to thin-layered chromatography (annex VI B), draw each 2 μ l of above-mentioned three kinds of solution, put respectively on same silica gel g thin-layer plate, with water saturated normal butyl alcohol for developping agent, launch, take out, dry, spray, with 1% vanillin-sulfuric acid solution, is inspected under putting ultraviolet lamp (365nm).In test sample chromatogram, on the position corresponding to reference substance chromatogram, aobvious identical blue-fluorescence spot.
But, in this discrimination method, adopt Saponin A, B reference substance and spinosin reference substance, spina date seed control medicinal material is contrast, respectively saponins and flavones ingredient in discriminating spina date seed, such method both improve testing cost, operated comparatively loaded down with trivial details again.
For the quality control of effective constituent in spina date seed medicinal material, Chinese Pharmacopoeia adopts high performance liquid chromatography to carry out assay to saponins and flavones ingredient respectively.But, in this content assaying method, the traditional Chinese medicine quality control model still followed conventional lines, namely with Saponin A, B or spinosin reference substance etc. in contrast, carry out Quality Evaluation Analysis to spina date seed, this mode evaluation index is relatively single, too relies on traditional Chinese chemical contrast, not environmentally, testing cost is high.
Summary of the invention
Based on this, be necessary for the problems referred to above, prepare a kind of spina date seed reference extract, and it can be used as tester to be applied in spina date seed and the quality control containing the Chinese medicine preparation of spina date seed, there is feedback component information comprehensive, and easy and simple to handle, that testing cost is low advantage.
