RESUMO
This study was designed to investigate the flavor and taste change rules of Sophora Flavescentis Radix processed using the ancient classical method documented in Master Lei's Discourse on Medicinal Processing(Lei Gong Pao Zhi Lun). The Sophora Flavescentis Radix pieces and the corresponding test samples in each processing stage were first prepared based on the processing method for Sophora Flavescentis Radix recorded in Master Lei's Discourse on Medicinal Processing(Lei Gong Pao Zhi Lun). Then the flavors and tastes of Sophora Flavescentis Radix test samples undergoing the soaking in rice-washed water, washing with clean water, and steaming for different time were compared with the electronic nose and tongue. The results showed that in the preparation of Sophora Flavescentis Radix with the ancient method, such processes as soaking in rice-washed water and washing with clean water had no significant influences on the flavor, which, however, was weakened by steaming. In terms of the taste, soaking with rice-washed water enhanced the bitter taste of Sophora Flavescentis Radix, which remained unchanged after being washed with the clean water. The steaming would also diminish the bitter taste, making it taste similar to the original Sophora Flavescentis Radix medicinal materials. During the steaming for six to eight hours, the flavor did not vary significantly over time, while the bitter taste was first weakened and then intensified. The bitter taste of Sophora Flavescentis Radix steamed for six hours was similar to that steamed for eight hours. In addition, the differences in flavor and taste between Sophora Flavescentis Radix pieces processed by the ancient method in Master Lei's Discourse on Medicinal Processing(Lei Gong Pao Zhi Lun)and those by the modern method in the 2020 edition of Chinese Pharmacopoeia were analyzed. The findings demonstrated that the flavor of Sophora Flavescentis Radix pieces prepared by the ancient method was weaker than that by the modern method, whereas the bitter taste showed the opposite trend. The exploration on the flavor and taste change rules of Sophora Flavescentis Radix in its preparation by the ancient classical method and the differences in flavor and taste between Sophora Flavescentis Radix decoction pieces prepared by ancient and modern methods will lay a foundation for further elucidation of the scientific connotation of the ancient processing method and the medication principles of Sophora Flavescentis Radix in both ancient and modern times.

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.

The use of combination drugs is considered to be a promising strategy to control complex diseases such as ischemic stroke. The detection of metabolites has been used as a versatile tool to reveal the potential mechanism of diverse diseases. In this study, the levels of 12 endogenous AAs were simultaneously determined quantitatively in the MCAO rat brain using RRLC-QQQ method. Seven AAs were chosen as the potential biomarkers, and using PLS-DA analysis, the effects of the new combination drug YQJD, which is composed of ginsenosides, berberine, and jasminoidin, on those 7 AAs were evaluated. Four AAs, glutamic acid, homocysteine, methionine, and tryptophan, which changed significantly in the YQJD-treated groups compared to the vehicle groups (P < 0.05), were identified and designated as the AAs to use to further explore the synergism of YQJD. The result of a PCA showed that the combination of these three drugs exhibits the strongest synergistic effect compared to other combination groups and that ginsenosides might play a pivotal role, especially when combined with jasminoidin. We successfully explored the synergetic mechanism of multi-component and provided a new method for evaluating the integrated effects of combination drugs in the treatment of complex diseases.

OBJECTIVE: To compare the contents of the main chemical compositions in Gardenia jasminoids before and after being roasted with ginger juice. METHOD: 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). RESULT: After being processed with ginger juice, the contents of the diterpenoid pigments constituents decreased slightly and the contents of the iridoids constituents increased slightly. CONCLUSION: 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.

OBJECTIVE: To investigate the regularity of changes in the main active components of Schisandra chinensis preparations before and after being processed with vinegar. METHOD: 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. RESULT: 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). CONCLUSION: 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.
