ABSTRACT
In this experiment,the gradation analysis method was used to evaluate the quality of different pieces of Gardeniae Fructus through the extraction rate difference and the difference analysis of the main components in the extract. In this experiment cold-dip and hot-dip methods were used to compare the yield of Gardeniae Fructus extract and the content of chemical constituents with water,25%,50%,75% and 95% ethanol fractions. By weighted calculation,the optimal extraction method of Gardeniae Fructus was determined,and this was verified by practical application. RESULTS:: showed that for the water-soluble extract,cold dip method was better than the hot dip method; and for alcohol-soluble extract,75% ethanol under cold dip method was best. The verification results showed that water-soluble extracts under cold dip methods could be used to significantly distinguish the raw Gardeniae Fructus( GF) and processed( stir-baked) GF( GFP) collected from the market. Meanwhile,this method could be also used to distinguish the same batch of GF,GFP and carbonized GF( GFC) with significant differences,respectively( P<0. 05). Ethanol-soluble extract can be used to clearly distinguish GFP and GFC pieces in the same batch( P<0. 05). The results of content determination showed that the variation coefficient of components in GF processed products was higher than that in extracts,and the content of hydroxygeniposide was the most significant component between GF and its processed products. It is suggested that the method of water-soluble extract of GF and the determination of the content of gardoside should be combined together to evaluate the quality of GF and its heat processed products.

Bupleuri Radix is a traditional Chinese medicine commonly used in clinical practice, which has the effects of relieving fever, relieving liver and depression, and promoting Yangqi. At present, the varieties of Bupleuri Radix are relatively chaotic, and the processing in the production areas is relatively extensive. In the processing of Bupleuri Radix, the processed products contained in the 2015 edition of Chinese Pharmacopoeia are raw products and vinegar-processed products. In addition, the specifications on Chinese medicine processing in various provinces and cities contain many processing methods, such as stir-frying with wine, stir-frying with honey, processed with turtle blood, etc. However, there are great differences in processing specifications among provinces and cities, and the processing methods lack clear process parameters, so the quality of Bupleuri Radix decoction pieces produced on these basis is uneven, which affects the clinical application of the decoction pieces. By consulting ancient books and relevant literature, the authors conduct textual research on the varieties of Bupleuri Radix, and systematically summarized the processing methods and processing methods in the producing area, so as to provide reference for the establishment of processing technology specifications and quality standards of Bupleuri Radix decoction pieces.
ABSTRACT
To elucidate the key issues in the development and innovation of traditional Chinese medicine processing discipline and Chinese herbal pieces industry Chinese herbal pieces industry. According to the author's accumulated experience over years and demand of the development of the Chinese herbal pieces industry, the key issues in the development and innovation on the Chinese herbal pieces industry were summarized. According to the author, the traditional Chinese medicine processing discipline shall focus on a application basis research. The development of this discipline should be closely related to the development of Chinese herbal pieces. The traditional Chinese medicine processing discipline can be improved and its results can be transformed only if this discipline were correlated with the Chinese herbal pieces industry, matched with the development of the Chinese herbal pieces industry, and solved the problems in the development on the Chinese herbal pieces industry. The development of traditional Chinese medicine processing discipline and the Chinese herbal pieces industry also requires scientific researchers to make constant innovations, realize the specialty of the researches, and innovate based on inheritance.
ABSTRACT
Gardeniae Fructus contains volatile ingredients, however, the species and proportions in different processed products of Gardeniae Fructus are different. In this experiment, volatile ingredients were separated by steam distillation with content of 1.2, 1.0, 0.9, 0.7 µL · g(-1) in Gardeniae Fructus, fried Gardeniae Fructus, stir-baked Gardeniae Fructus, Gardeniae Fructus fried into carbon respectively. One hundred and twenty-four kinds of volatile components were identified by GC-MS. Fifty-three kinds of volatile ingredients consisted in Gardeniae Fructus accounting for 93.85%, 54 kinds in fried Cardeniae Fructus accounting for 92.01%, 32 kinds in stir-baked Cardeniae Fructus accounting for 91.59% and 43 kinds in Gardeniae Fructus fried into carbon accounting for 90.81%. In this paper, analysis of Gardeniae Fructus by GC-MS provides a scientific basis for elucidating the mechanism of different processed products.

Processed Chinese medicine is the core of traditional Chinese medicine (TCM) industry chain,which directly affects the clinical efficacy and. safety of Chinese patent medicine and clinical formula Decoction pieces. Studied the variation of effective substance in vivo Chinese medicine processing before and after processed, clarifying the effective substance and processing principle is a top priority of the development of Chinese medicine processing. The traditional research method chiefly focus on the variation about chemicals in vitro of processed Chinese medicine, it cannot reveal that the integrity and complexity of processed Chinese medicine efficacy changes, so the change process is the focus of future research in vivo on the base of effective substance of TCM This paper described the research on the base of effective substance of TCM and Processed Chinese medicine research status in vitro, discussed the analytical methods (plasma chemistry, pharmacokinetics, metabonomics) of the dynamic process in vivo about processed Chinese medicine, and pointed out development and related problems in process in vivo on the base of effective substance of TCM, which could provided research ideas and methods for in-depth interpretation of Chinese medicine processing mechanism.

<p><b>OBJECTIVE</b>To compare the contents of the main chemical compositions in Gardenia jasminoids before and after being roasted with ginger juice.</p><p><b>METHOD</b>Four diterpenoid pigments constituents (C-1, C-2, C-3, crocetin) were determined simultaneously by UPLC on an Agilent Poroshell 120 EC-C18 column at 35 degrees C with the methanol-0.5% formic acid anhydrous in gradient elution as the mobile phrase. The detection wavelength was set at 440 nm and the flow rate was 0.4 mL x min(-1). Two iridoids constituents (G-1, G-2) were determined simultaneously by HPLC on an Agilent TC-C18(2) column at 35 degrees C with acetonitrile-0.5% formic acid anhydrous (18:82) as the mobile phrase. The detection wavelength was set at 238 nm and the flow rate was 1.0 mL x min(-1).</p><p><b>RESULT</b>After being processed with ginger juice, the contents of the diterpenoid pigments constituents decreased slightly and the contents of the iridoids constituents increased slightly.</p><p><b>CONCLUSION</b>The contents of the main chemical compositions in G. jasminoids roasted with ginger juice increased slightly with some regularity, but there were no significant differences.</p>

<p><b>OBJECTIVE</b>To investigate the regularity of changes in the main active components of Schisandra chinensis preparations before and after being processed with vinegar.</p><p><b>METHOD</b>High performance liquid chromatography was used to analyze the changes in the content of lignans and organic acids in S. chinensis preparations before and after being processed with vinegar.</p><p><b>RESULT</b>After being processed with vinegar, the content of lignans in S. chinensis preparations significantly reduced, while that of organic acids significantly increased. The ratio between them reduced from 1:16 (raw product) to 1:21 (vinegar products).</p><p><b>CONCLUSION</b>The changes in the main pharmacological effects of S. chinensis are related to not only the changes in the contents of lignan and organic acids, but also the significant changes in the ratio relations between the two components. This is of great significance to the correlation among the principle of S. chinensis processed with vinegar and material basis and the changes in pharmacological effects.</p>
