RESUMO
Objective: To compare the difference of volatile specific odor components of Angelicae Sinensis Radix (ASR) processed by different methods such as yellow wine washing, dipping and firing, so as to provide research ideas for establishing the identification methods of different processed products of ASR and further study the mechanism of ASR traditional methods. Methods: Gas chromatography-ion mobility spectrometry (GC-IMS) was used to detect and compare the volatile components of ASR samples washed with different concentrations and processed by different methods, and compare the composition changes. PCA, partial least squares discriminant analysis (PLS-DA), and orthogonal partial least squares discriminant analysis (OPLS-DA) were used to analyze the differences in volatile components combined with SIMCA 14.1 software. Results: GC-IMS fingerprints showed that the volatile components of ASR at different concentrations were different. It was identified that the volatile components included 55 monomers and dimers and polymers of some substances. 2-Octanol, E-2-heptan aldehydes, acetone, 2-pentanone and 5-methyl-2-furan methanol could be used as the characteristic volatile substances of yellow wine washing of ASR. Ethyl acetate, 3-methyl-1-pentanol, 2-hexanol and ethyl 2-methylbutyrate could be used as characteristic flavor substances of yellow wine dipping of ASR. Furfural dimer, 3-methylbutanol and benzaldehyde could be used as characteristic volatile substances of yellow wine firing of ASR. The results of PCA showed that the resolution of each group of samples was good. PLS-DA analysis showed that 2-undecenal, 2-butanone, and acetone were different components with different concentrations yellow wine washing of ASR samples. OPLS-DA analysis showed that 2-undecenal, ethyl octanoate, dimer and acetone were the main components of ASR samples processed by different methods. Conclusion: The GC-IMS technology combined with stoichiometry proved that the volatile components of ASR processed by yellow wine washing, dipping and firing were different, which provided a reference for further research on traditional processing methods in classical prescription.
RESUMO
To reveal the transformation and attribution of drug properties in Galla Chinesis fermented Baiyaojian by studying the effect of Galla Chinesis and Baiyaojian on cold and heat syndrome rats. Euthyrox was used to induce the hyperthyrosis model,ice water stimulation was used to induce the cold syndrome model,and different concentrations of Galla Chinesis and Baiyaojian water decoction were administrated by gavage for 15 d continuously. Symptom indexes were evaluated,content of pyruvic acid( PA),ATPase activity in liver and contents of DA,T4,cAMP,5-HT,NE,17-OHCS,TRH and TSH in serum were assayed by enzyme linked immunosorbent assay and spectrophotometry. The rectal temperature,water consumption and body weight of heat syndrome rats in model group were increased,cAMP,NE,17-OHCS,TRH and PA were increased,TSH,Na-K ATPase and Ca-Mg ATPase were increased significantly( P<0. 01),while 5-HT was decreased,compared with those of the blank group( P< 0. 05),the contents of T4,DA,NE,TSH,TRH,cAMP and 17-OHCS were decreased significantly( P<0. 01),PA and Ca-Mg ATPase in WG and BG groups were decreased compared with those of the model group( P<0. 05),and the Galla Chinesis content of WG group was lower than that of BG group,while the contents of 5-HT in WG and BG groups were increased,and the Galla Chinesis content of WG group was higher than that of BG group,with no significant difference of viscera index between heat syndrome rats in blank group,model group and drug groups. The rectal temperature,water consumption and body weight of cold syndrome rats in model group were decreased,DA,T4,cAMP,NE,17-OHCS,TRH,TSH,PA,Na-K ATPase and Ca-Mg ATPase of rats in model group were decreased,whereas 5-HT was increased compared with those of the blank group( P<0. 05),the indexes of heart,lung and kidney were significantly higher than those in the blank group( P<0. 05). Both Galla Chinesis and Baiyaojian can significantly alleviate the symptoms of heat syndrome rats caused by levothyroxine sodium. Galla Chinesis has a better effect than Baiyaojian,but cannot alleviate the symptoms of cold syndrome caused by ice water stimulation,suggestting that the decoction of Galla Chinesis and Baiyaojian are both cold,but Galla Chinesis is colder than Baiyaojian. Cold property in Galla Chinesis fermented Baiyaojian can be relieved. In clinical application,the property of " slight cold" is more accurate than " neutral property" for Baiyaojian.
