Chuanxiong Chatiaosan was first recorded in Taiping Huimin Heji Jufang, which was made up of 8 herbs, including Chuanxiong Rhizoma, Menthae Haplocalycis Herba, Asari Radix et Rhizoma, Schizonepetae Herba, Saposhnikoviae Radix, Angelicae Dahuricae Radix, Notopterygii Rhizoma et Radix and Glycyrrhizae Radix et Rhizoma. This prescription mainly contains a variety of alkaloids, flavonoids, phenylpropanoids, volatile oils and other compounds, which play the biological activity of promoting blood circulation and relieving pain. Modern pharmacological studies have confirmed that Chuanxiong Chatiaosan can reduce blood viscosity, improve cerebral circulation, and has central analgesic effect to treat migraine effectively. However, the mechanism for treating migraine of this prescription is still unclear. The author elaborated the research status of Chuanxiong Chatiaosan from four aspects, including quality control method, chemical composition, preparation technology and pharmacological research, hoping to provide references for rational clinical application and explanation of pharmacological mechanism of this prescription.

The chromaticity space parameters of the samples during the processing of Gardeniae Fructus Praeparatus(Jiaozhizi in Chinese herbal name, JZZ) were measured by the visual analyzer to analyze the color variation rule during the processing of JZZ, and the content changes of total reducing sugar, total amino acid and 5-hydroxymethylfurfural(5-HMF) related to Maillard reaction were measured. Pearson correlation analysis and linear regression analysis of the data were carried out by SPSS 24.0 software. The experimental results showed that the objective coloration of the samples in the processing of JZZ was basically consistent with the traditional subjective color judgment; the contents of total reducing sugar and total amino acids showed a decreasing trend during the processing of JZZ, and the content of 5-HMF showed an increasing trend, which was in line with Maillard reaction law. Pearson correlation analysis results showed that there was a significant correlation between the chromaticity space parameters L~*(lightness value), a~*(red green value), b~*(yellow blue value), E~*ab(total color value) and the contents of total reducing sugar, total amino acid and 5-HMF(P<0.01), among which the values of L~*, a~*, b~*, E~*ab were positively correlated with the contents of total reducing sugar and total amino acid, and negatively correlated with the contents of 5-HMF. The results of linear regression analysis also showed that these two were highly correlated. In this study, by establishing the correspondence relationship between the color change of JZZ processing and Maillard reactants, wecan not only provide a basis for the objective digital expression of subjective color of JZZ, but also provide a reference for explaining the processing mechanism of JZZ from a new perspective.

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.

Ischemic stroke is one of the diseases that seriously threaten human health. It is characterized by the high morbidity, disability rate and mortality, and has been lacking effective treatment. Its occurrence is related to metabolic disorder, calcium overload, free radical injury, inflammatory reaction, etc. Gardeniae Fructus not only has antipyretic, analgesic, hepatoprotective and cholagogic effects, but also has protective effects against ischemic brain injury. At present, there are more studies about the main components of Gardeniae Fructus against ischemic brain injury, but the mechanism is unclear. In this paper, the mechanism of the main active ingredients from Gardeniae Fructus in the treatment of cerebral ischemia injury in recent years was reviewed, and the effective component monomer and the whole were analyzed, so as to provide a basis for the prevention and treatment of ischemic brain injury of Gardeniae Fructus decoction pieces, and provide a reference for further research and application of this decoction pieces.

Commercially available japonica rice and indica rice with different trade names were collected,and then based on the method of rice stir-frying,their many indexes were evaluated,for example the physical and chemical properties such as appearance color,grain type,broken kernel ratio,length-width ratio,1 000-grain weight,specific heat capacity,moisture content,amylose content,and protein content. The discriminant function analysis was used to determine the effective factors affecting the quality of rice as excipients. The results showed that two types of rice could be distinguished by rice color parameter a*,grain parameter circularity,1 000-grain weight and amylose content. These four effective factors can be used as the quality evaluation indexes for fried rice as excipients.Protein is one of the main components of rice,and its content affects the quality of rice. There is a significant difference in the protein content between japonica rice and indica rice. Therefore,protein content should be used as one of the evaluation indexes for rice quality. After comprehensive consideration,it is suggested that the red-green value a*shall not be less than 0. 50; the circularity not less than 53. 0,the 1 000-grain weight not less than 16. 0 g,the amylose content not less than 12. 0% and the protein content not less than4. 0% in the japonica rice; the red-green value a*shall not be lower than-1. 0,the circularity not less than 41. 0,the 1 000-grain weight not less than 13. 0 g,the amylose content not less than 9. 0% and the protein content not less than 3. 5% in the indica rice. In this study,the quality evaluation standards for rice as excipients( japonica rice,indica rice) were supplemented and improved,laying foundation for the development of quality standards for rice as excipients with the rice stir-frying method.

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.
