ABSTRACT
Objective:To find out the transformation reasons of the processing methods for Matrii sultas Exsiccatus through the bencaological study and the modern experimental researches.Methods:The different processing methods for Matrii sultas Exsiccatus in different periods were collected through the researches on the ancient agrostology and the modern processing standards.Furthermore,different processed products were prepared and analyzed by Raman spectroscopy.Results:There were significant differences in the processing methods for Matrii sultas Exsiccatus in the ancient herbal documents while tending to be the same in the modern processing standards.No difference was shown in the Raman spectrogram between Matrii sultas Exsiccatus and Weathered mirabilite produced by the processing methods in the ancient agrostology.The Raman characteristic peaks of the two processed products were as follows:1 153,1 132,1 102,992,648,632,621,466,450 cm-1,which were in line with the Raman spectrogram of the products produced by the modern processing methods.Conclusion:The change of processing methods for Matrii sultas Exsiccatus has certain reasons,which is worthy of further studies.
ABSTRACT
Gypsum Fibrosum is one of mineral medicines, which is widely used in clinics for a long time. It is mainly used for treating epidemic febrile diseases and excess-heat syndrome. The studies on the heat-clearing effects and mechanisms of Gypsum Fibro-sum in recent years were summarized in the paper,which can provide scientific reference for its further research, application and the heat-clearing mechanism exploration.
ABSTRACT
Compared with that for botanical drugs and animal-derived drugs, the identification study for mineral traditional Chi-nese medicines is relatively weak. The traditional identification methods can’ t meet the quality control requirements of mineral tradi-tional Chinese medicines, and the application of modern analysis techniques are needed urgently in the systematic research of mineral traditional Chinese medicines. In the paper, the identification of traditional methods combined with some modern analysis techniques such as X-ray diffraction, near infrared spectroscopy and Raman spectroscopy for mineral traditional Chinese medicines was summarized and analyzed to provide basic idea and methods for the systematic identification construction of mineral traditional Chinese medicines.
ABSTRACT
Objective:To understand the development reality of pastes in Hubei province through the investigation of paste busi-ness in 2013. Methods:Issued by Hubei provincial administration of traditional Chinese medicine, a questionnaire investigation was a-dopted in the study. The implementation, usage amount, scope, composition of the users, price, technical personnel and propaganda of pastes were investigated and statistically analyzed in 91 TCM, integrated Chinese and western and national hospitals in our province. Results:The business conduction rate of pastes in Hubei province was nearly 61. 54% in 2013 with the production of approximately 45,000 batches and the technical personnel of 1 538. The paste business created great economic value of 0. 48 million yuan in 2013 with strengthened propaganda. However, the brand building was slightly weak. Conclusion:The business of pastes in Hubei province has developed rapidly and still shows great development potential.
ABSTRACT
Objective:To develop a method for the rapid determination of CaSO4 ·2H2 O in gypsum by Raman spectra. Methods:Totally 40 batches of gypsum from different origins were used as the training set, compared with the results by ENTA titration, and OPUS software was used to establish a quantitative analysis model of CaSO4 ·2H2 O in gypsum by Raman spectra. Results:The estab-lished quantitative analysis model could provide a good prediction result rapidly when the content was between 97. 93% and 99. 81%. Conclusion:The method is accurate, fast and simple, which can be developed as an analysis method for CaSO4 ·2H2 O in gypsum.
ABSTRACT
Objective:To develop a qualitative analysis model for the fast identification of Dens Draconis and its adulterants by NIR correlation coefficient method. Methods:On the basis of the traditional morphological identification, the spectra were collected u-sing the fiber accessory of a near-infrared spectroradiometer. The reference spectra were set up using the NIR spectra of certified Dens Draconis. The characteristic spectral section was chosen and the appropriate threshold was set to establish a qualitative analysis model for the rapid identification of Dens Draconis and its adulterant. Results:The spectral section of 5 000-4 200 cm-1 was selected as the characteristic spectral section, the correlation coefficient of Dens Draconis and its adulterant was calculated in training set samples, and 92. 67% was used as the threshold. Totally 10 batches of validation set samples were validated the qualitative analysis model, and the prediction accuracy was 90%. Conclusion:The method has good prediction ability, and can be used in the rapid identification of Dens Draconis and its adulterant.
ABSTRACT
To establish seven kinds of minerals containing sulfate kind of near infrared spectral identification method of traditional Chinese medicine (TCM). 7 species of mineral medicine containing sulfate after crushing sieving, measure all the samples in 12 000-4 000 cm-1 section within the scope of the near infrared spectrum, spectrum signal by different pretreatment methods, after the screening of the different characteristics of the spectrum to extract the effective information, using cluster analysis method for qualitative identification. In 8 600-8 100 cm-1, 5 843-4 245 cm-1, 7 096-6 337 cm -1 section within the scope of the atlas signal after the vector normalization and multiple scattering correction, K-average clustering analysis to 20 batches sulfate kind of mineral medicine is divided into seven categories, the results of the analysis method and the traditional traits identification results are basically identical. This method is simple, fast, and can be used for these minerals containing sulfate class the qualitative identification and quality control of Chinese traditional medicine.
ABSTRACT
This study was aimed to establish a qualitative model of near-infrared spectroscopy in order to accurately and rapidly identify several mineral Chinese medicinals from fossil including Os Draconis, Dens Draconis, Fossil Shell of Spirifer, and Fossil Crabs. The near-infrared diffuse reflectance spectroscopy combined with OPUS software was used to analyze the spectral characteristics of these samples. The pattern recognition method was explored through cluster analysis. And the accuracy of the model was verified. The results showed that these mineral Chinese medicinals from fossil had their characteristics absorption so that they can be quickly and accurately differentiated from each other through pattern recognition method. It was concluded that based on near-infrared spectroscopic mod-eling, these mineral Chinese medicinals from fossil including Os Draconis, Dens Draconis, Fossil Shell of Spirifer, and Fossil Crabs can be quickly and accurately identified.
