[Study on quality standard of fried Vaccariae Semen standard decoction].

According to the preparation principle of standard decoction of Chinese herbal medicines, fourteen batches of fried Vaccariae Semen decoction were prepared in this study and the quality research was carried out to establish a quality evaluation method for the standard decoction of fried Vaccariae Semen. The contents of vaccarin were determined, and its transfer rate from decoction piece to standard decoction was calculated. The extract rate and pH value were measured, and HPLC fingerprint method was established for analysis. The results of the 14 batches of samples revealed that the transfer rates of vaccarin were between 58.98%-93.94%; the extract rates were between 8.67%-17.83%, and the pH values were between 5.55-6.44. Moreover, 9 common chromatographic peaks were identified in fingerprints analysis. The similarities of the 14 batches of samples were analyzed and compared, and the results showed that the similarities were all higher than 0.96. In this study, the preparation process for fried Vaccariae Semen standard decoction was standard, with high similarities in fingerprint. A convenient and reliable method of comprehensive quality evaluation was established in this study, with a high precision, stability and repeatability, which can provide a reference for the quality control of fried Vaccariae Semen standard decoction, dispensing granule and related Chinese classical formulas(decoction).

Analysis of standard decoction of salt-processed Psoraleae Fructus / 中国中药杂志

The traditional Chinese medicine standard decoction is prepared on the basis of the theory of traditional Chinese medicine and clinical application. With reference to the modern extraction method,the single decoction of traditional Chinese medicine is prepared by the standardized process,and the establishment of its quality standards is conducive to standardizing clinical medication. This research is to set an evaluation standard for the quality of salt-processed Psoraleae Fructus standard decoction. Twelve batches of salt-processed Psoraleae Fructus standard decoctions were prepared. The contents of psoralen and isopsoralen were determined,the transfer and extract rates were calculated,and the pH value was measured; HPLC fingerprint method was established for analysis. The results of the 12 batches of samples revealed that the transfer rates of psoralen and isopsoralen were 17. 10%-26. 40%,14. 70%-22. 70%,respectively; the extract rate was between 14. 7%-27. 0%,and the pH value was between 5. 4-6. 9. Moreover,7 common chromatographic peaks were determined based on fingerprint by using similarity evaluation system for chromatographic fingerprint of traditional Chinese medicine( 2012 A).The similarities of the 12 batches of samples were analyzed and compared,and the results showed that the similarities were all higher than0. 9. In this study,the preparation method for salt-processed Psoraleae Fructus decoction was standard,with high similarities in fingerprint. This study build a convenient and reliable method of comprehensive quality evaluation,with a high precision,stability and repeatability,which can provide a reference for the quality control of salt-processed Psoraleae Fructus dispensing granules.

Analysis on Medication Rules of National Medical Masters in Treatment of Stomachache / 中国实验方剂学杂志

Objective: To analyze medication rules of national medical masters in the treatment of stomachache by data mining. Method: Prescriptions were collected from 9 works as well as the first batch of national medical masters' medical cases and prescriptions for stomachache recorded in CNKI. Then, Microsoft Excel 2016 was adopted for analyzing the frequencies, properties, flavors and meridian tropisms of herbs, the Apriori algorithm provided by SPSS Clementine 12.0 software was used to analyze association rules of the herbs, and factor analysis was conducted by SPSS 19.0 software. Result: A total of 175 prescriptions containing 230 herbs were selected. The top five herbs used in frequency ranking were Glycyrrhizae Radix et Rhizoma, Paeoniae Radix Alba, Pinelliae Rhizoma, Atractylodis Macrocephalae Rhizoma, Poria. The medical properties with high usage frequency were warm, mild and slight cold. The flavors were sweet, bitter and pungent. Meridian tropisms were spleen, stomach and lung. Herbs for regulating Qi, tonifying Qi and promoting digestion ranked top three according to the classification of efficacy. The association rules analysis showed that the highest confidence and support of the related drugs was Atractylodis Macrocephalae Rhizoma→Codonopsis Radix-Poria, which reflected treatment characteristics of national medical masters with Sijunzitang as the basic prescription for tonifying Qi. A total of 12 strongly association rules of 2-drug pairs were obtained by association rules, and the most commonly used of which was Paeoniae Radix Alba-Glycyrrhizae Radix et Rhizoma. Nine common factors were respectively extracted by factor analysis. Conclusion: Herbs used in the prescriptions of national medical masters for treatment of stomachache are often with the actions of regulating Qi, invigorating deficiency and benefiting Qi, in addition, Shaoyao Gancaotang is often used to generate Yin and relieve pain.
