Correlation Analysis Between Color and Content Changes of Five Components of Wine-processed Polygonatum kingianum Rhizoma During Processing / 中国实验方剂学杂志

ObjectiveTo study the correlation between the appearance color of the sample powder and the contents of five non-sugar components of wine-processed Polygonatum kingianum rhizoma during processing， and determine the feasibility of color quantitative value for judging the processing end point of the wine-processed products， and to screen steroidal saponins and flavonoids as markers for the control of the wine-processed products during processing. MethodThe changes of apparent color of the sample powder at different time points of the wine-processed products were measured by colorimeter， and the total color value （E*ab），the total color difference value （ΔE*ab） were calculated. The contents of protodioscin， pseudoprotodioscin， dioscin， diosgenin and narcissoside in the wine-processed products （No. S0-S10） after processing for 0， 5， 10， 14， 16， 18， 20， 22， 24， 26， 28 h were determined simultaneously by ultra-high performance liquid chromatography-tandem mass spectrometry （UHPLC-MS/MS）. Cluster analysis （HCA）， principal component analysis （PCA）， partial least squares discriminant analysis （PLS-DA） and Pearson correlation analysis were used to analyze the chromaticity value of the sample powder and the content of the five components. ResultDuring processing of wine-processed P. kingianum rhizoma， E*ab of the sample powder showed a decreasing trend and the apparent color changed from light yellow to lacquer black. The contents of the five components showed an obvious dynamic change trend with time， and showed different laws. HCA results showed that the processing process of the wine-processed products could be divided into three stages， namely， the early stage （samples S0-S1）， the middle stage （samples S2-S4） and the late stage （samples S5-S10）. PCA results showed that there were significant differences in color and contents of five components between the initial sample and the processing samples， and the difference between samples S8 and S9 was the smallest. PLS-DA results showed that the variable importance in the projection （VIP） values of b*， the contents of pseudoprotodioscin， narcissoside， diosgenin and protodioscin were >1. Pearson correlation analysis showed that the contents of protodioscin， diosgenin and narcissoside had a significant positive correlation with E*ab （P<0.01）， the content of diosgenin had a significant negative correlation with E*ab （P<0.01）， while the content of pseudoprotodioscin had no linear correlation with E*ab. ConclusionIn the process of wine-processed P. kingianum rhizoma， there is a certain linear correlation between color quantitative value and chemical composition， and the processing end point can be determined objectively. It can be considered that protodioscin can be used as a marker for the control of the wine-processed products.

ObjectiveTo compare the differences in resistance and structure of skin between acupoints and non-acupoints， and to study the difference in skin permeability characteristics of Corydalis Rhizoma total alkaloid patches （CTTP） after administration at Shenque acupoint and non-acupoint， so as to provide experimental support for its clinical acupoint application to prevent and treat chronic pain. MethodTaking corydaline （CD）， tetrahydropalmatine （THP） and corydalis L （CDL） as evaluation indexes， and the quantitative analysis was carried out by high performance liquid chromatography （HPLC）. The mobile phase was methanol-0.04 mol·L-1 phosphoric acid aqueous solution （70∶30， pH 6.0 adjusted with triethylamine）， the detection wavelength was 281 nm. In vitro transdermal test in Franz diffusion cell and in vivo transdermal test were used to study the skin permeability characteristics of CTTP through Shenque acupoint and non-acupoint administration. At the same time， the skin resistance between Shenque acupoint and non-acupoint was measured before and after the administration， and the distribution of the drug in each layer of the skin was compared by freezing sectioning， and visual verification was performed with fluorescence inverted microscope. ResultAfter 24 h of administration， the results of in vivo and in vitro experiments showed that the cumulative permeation and retention of CD， THP and CDL at Shenque acupoint skin were higher than those at non-acupoint skin （P<0.05， P<0.01）， the skin resistance of Shenque acupoint was lower than that of non-acupoint at all time points. The fluorescence microscopic observation results showed that the drug content of each layer of the skin was all Shenque acupoint>non-acupoint， indicating that the skin of Shenque acupoint had better effect on drug penetration and storage than non-acupoint. ConclusionThe 24 h cumulative permeation and retention of CTTP in Shenque acupoint skin are higher than those in non-acupoint skin， and the mechanism may be related to the thin skin， low electrical resistance and large number of hair follicle bodies at Shenque acupoint.
