| The roses and apocynum is important as a food and drug resources.Rose(Rosa rugosa thunb) is rosaceae rose perennial evergreen or deciduous shrubs. In our country has two thousand years of medicinal history, mainly distributed in places such as Shandong, Gansu, Inner Mongolia, Xinjiang area mainly concentrated in hotan region, and is given priority to with Damascus rose varieties. Rose essential oil, tannin, the antioxidant glucoside, bitter principle, tannins, polyphenols, gallic acid and other active ingredients, with boredom, resolve depression, detoxification, strong strong stomach qi, liver, lungs, can remove the adr caused by such as antibiotic substances, balance the endocrine physiological function. Market rose tea with dry buds or petals, due to the complexity of roses composition, is not yet perfect, the quality evaluation indexes in the 2010 edition pharmacopeia only sensory properties, microscopic identification were a few simple indicators, such as the lack of effective detection index, for easy to mix Chinese rose, rose only relies on the sensory properties are difficult to accurately identify.Apocynum(Apocynum venetum L.) is apocynaceae Apocynum perennial root perennial subshrub plant, in our country are mainly distributed in xinjiang, Inner Mongolia, shaanxi, gansu, qinghai, shandong, jiangsu coastal areas of the Yellow River communist-held coast, etc. Apocynum contains flavonoids, tannins, acid, catechins, fatty acid glycol ester, alcohol, nonsteroidal, sugars, alkanes, amino acids, and minerals, and other active ingredients, with a flat heart palpitations, blood pressure, antidepressant, check dizziness, cough asthma and efficacy, the strong heart diuresis. In many areas are distributed in xinjiang, in altay, relatively concentrated, mainly kenaf, white linen, three big bluish dogbane, but for the classification of apocynum can put white linen with big gray linen to dispute, included in the pharmacopoeia of kenaf, and widely used in white linen in uygur medicine, both have the same medicinal value remains to be further research.This article mainly by the infrared fingerprint, infrared three-level identification method, to control the quality of the roses and apocynum, make up for the inadequacy of existing detection technology, roses for objective quality assessment, implementation and falsify rapid identification of macro control, active ingredients of apocynum, provide new experimental basis for the classification of apocynum. The main research content and the results are as follows:1. Roses in xinjiang and the establishment of apocynum ir fingerprint successfully identify its macroscopical fingerprint characteristic peak and establish the fingerprint of apocynum fingerprint characteristic absorption peak of 3314, 2919, 2850, 1614, 1540, 1614, 1614, 1248, 1200, 1100, 658 and 1200 cm-1, 2919, 2850, 1444 and 1100 cm and 1375 cm-1 wide strong peak, near the rose fingerprint characteristic absorption peak for 3329, 2926, 1734, 2926, 1734, 1448, 1345, 1218, 1040, 832, 759 and 1040 cm-1, 1468 in the second derivative spectra, 1316, 833, and 1316 cm-1;2. By means of ir three-level identification method for effective analysis found that the high temperature of different drying methods, type bluish dogbane and microwave processing of bluish dogbane leaf can cause change characteristic absorption peaks of the flavonoids. Of apocynum, white linen and big Ye Bai hemp to identify classification, found that white linen and big Ye Bai hemp macroscopical fingerprint characteristic peak close to a close.3. To level 3 identification method for Chinese rose, rose and its mix goods found aromatic compounds exist obvious difference characteristic absorption peak, the rose in the second derivative spectra with different from Chinese rose three characteristic absorption peak of 1455, 1317 and 1156 cm-1, 2 d map automatically in the peak of 990, 1050, 1075, 1110, 1190, 1260, and 1190 cm-1;... |
