Leaf Fluorescence Spectroscopy Study of Chinese medicine

Fluorescence of 7 for the small group of leafy Identification of traditional Chinese medicine. Fluorescence spectrometry that Lou Ye has a good effect of Chinese medicine, can identify genuine and counterfeit goods, some raw materials and processed products, to provide for the identification of the small leaf of Chinese medicine, a new analysis method. Keywords Kyu Kyu Kyu main limonene Bei Grand Fort Kam j take medicine cause leaf collection, drying, processing, transportation and other processes, its shape more shrinkage broken, incomplete,[link widoczny dla zalogowanych], its population Chinese character identification difficult; fork for leaf containing large amounts of chlorophyll, tannin and other components, the general physical and chemical identification to be ineffective. We used fluorescence spectroscopy to 7 group of leafy traditional Chinese medicine to achieve better sealing results of observation, reported as follows: 1 RF instrumentation and reagents for a 540 fluorescence spectrophotometer (Shimadzu); anhydrous ethanol (excellent grade pure). 2. Experimental samples (1) leaves (FoliumArtemisiaeArgyi) group; (2) senna (FoLiumSe ~ mae) New Zealand; (3) credit 'cLadi) group; (5) Folium (Folitwalsatidis) group; (6), loquat (Folitm ~ Eri.olmtryae) group; (7) basil leaves (FotiumPerillae) New York. Samples above the standard reference substance for medicinal drugs and biological products from China provided; medicine samples counterfeit provided by the Jinan Municipal Institute for Drug Control. 3. Experimental results are shown in fluorescence spectral characteristics of leafy herbs table. 4. Medicine in a standard 4.1 discussion refer to the following reference substance for identification, easy to identify authenticity. Groups such as the basil leaves. 4.2 The repeated experiments showed that a variety of samples, the same kind of genuine fluorescence spectral characteristics of leafy herbs are basically the same,[link widoczny dla zalogowanych], and stability, and reproducible. Genuine and counterfeit products 4.3 leafy herbs Huang Guangguang spectrum can be clearly differentiated. 3 loquat set of samples, such as counterfeit heather leaves, and authentic (sample 1) were significantly different. 4.4 Some students may be differences between goods and Mizhi processed, such as the set of samples 2 Mizhi loquat leaves,[link widoczny dla zalogowanych], and sample 1 (raw materials) can be identified.

Also, we found with the same plant it is often the old magpie grass, geranium G. palm mouse sibirictm ~ L. Other mix. To further understand its medicinal value, we conducted a preliminary study of pharmacognosy the following: 1.
