[Flavorand taste change rules of Sophora Flavescentis Radix processed using ancient classical method:an exploration based on intelligent sensory analysis].

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.

[Similar change laws of content of nine components in four processing methods of Polygoni Multiflori Radix Praeparata].

To standardize the processing technology of Polygoni Multiflori Radix Praeparata and stabilize its quality, the similar change laws of Polygoni Multiflori Radix Praeparata with different processing methods and time were analyzed. The processing time of Polygoni Multiflori Radix Praeparata was studied at 24, 32, 40, 48 h, and 4 different processing methods were studied, namely stewed with black bean sauce, steamed, steamed with black bean sauce, and steamed with black bean sauce and rice wine. The content of stilbene glycosides and anthraquinones were determined by HPLC-DAD method. UV method was used to determine the content of polysaccharides, and HPLC-ELSD method was used to determine the monosaccharides and oligosaccharides. The comparative chart of content determination, cluster analysis and entropy weight TOPSIS model was used to find the similar change laws and time interval of different processing methods of Polygoni Multiflori Radix Praeparata. The results demonstrated that around 32 h, the content of nine components in Polygoni Multiflori Radix Praeparata with different processing methods had similar change laws, and the decoction pieces had a high quality, indicating that the four processing methods of Polygoni Multiflori Radix Praeparata are likely to be used as one type of decoction piece with the same name.
