optimizing the preparation conditions and chromatographic conditions of the test solution,the UPLC characteristic maps of Codonopsis pilosula,millet-fried Codonopsis pilosula,and rice-fried Codonopsis pilosula were established,and methodological investigations were carried out to prove that the method is stable and feasible.The UPLC fingerprints of 9 batches of Codonopsis pilosula products have 6common peaks.Millet fried Codonopsis pilosula and rice fried Codonopsis pilosula each have 10 common peaks,and the similarities are both greater than 0.90.Two common peaks of 5-HMF and Lobetyolin are identified.The UPLC fingerprint of Codonopsis pilosula"rice"has obvious common peak characteristics,and the peak areas of chromatographic peaks 3,5,6,and 7 are significantly increased.Compared with the fingerprints of millet fried Codonopsis pilosula,the fingerprints of rice fried Codonopsis pilosula are basically the same except for peaks 6,7 Except for the same,the peak areas of other chromatographic peaks are relatively large.The results of cluster analysis and principal component analysis showed that 9 batches of Codonopsis pilosula were clustered into one category,while millet-fried Codonopsis pilosula and rice-fried Codonopsis pilosula clustered into another category.Using UPLC-Q-Exactive-MS/MS technology,combined with database and literature,a total of 41 chemical components were identified,mainly lactones,organic acids and phenylpropanoids,including abscisic acid,syringaldehyde,and osmanthus Oxalin and caffeic acid are unique components in Codonopsis pilosula;lactose and 6-gingerol are uniquecomponentsinmilletfriedCodonopsispilosula;(+)-pinoresin-β-D-glucopyranoside,quercetin,adenine,Luteolin only exists in Codonopsis pilosula and rice-fried Codonopsis pilosula;5-hydroxymethyl furfural exists in millet-fried Codonopsis pilosula and rice-fried Codonopsis pilosula.3.Pharmacodynamic research of Codonopsis pilosula participating in different rice frying in rats with spleen deficiencyEach administration group can increase the body mass of rats with spleen deficiency,improve gastrointestinal function,immune function,and water and fluid metabolism indexes,and have certain therapeutic effects on spleen deficiency.Compared with the model group,the last swim time,CK content,the D-xylose excretion rate,small intestine propulsion rate,GAS,MTL,VIP,spleen index,thymus index,total number of white blood cells,AQP 3 and Na~+-K~+-ATPase content in different rice-fried Codonopsis pilosula groups are different Increased;SS,Ig G,TNF-αcontent and CD4~+/CD8~+ratio decreased to varying degrees,indicating that different rice-fried Codonopsis pilosula can improve the symptoms of spleen deficiency in rats to varying degrees.In terms of regulating gastrointestinal function,compared with the millet-fried Codonopsis pilosula group,the GAS content of the rice-fried Codonopsis pilosula group was higher,and there was a significant difference(P<0.05);the two groups had a significant effect on body weight gain,small intestinal advancement rate and urine Although there is no significant difference in the comparison of xylose excretion rate,MTL,VIP,and SS,the rats in the millet-fried Codonopsis pilosula group gained more weight,with higher MTL and VIP content;while the small intestinal propulsion rate and urine D-xylose in the rice-fried Codonopsis pilosula group The excretion rate is higher and the SS content is lower.In terms of immune function regulation,compared with the millet-fried Codonopsis pilosula group,the rice-fried Codonopsis pilosula group had higher thymus index,lower IL-6 content(P<0.05),lower spleen index and TNF-αcontent,total number of white blood cells,CD4~+/The CD8~+ratio and Ig G content were higher,but there was no significant difference(P>0.05).In terms of regulating water metabolism,compared with the millet-fried Codonopsis pilosula group,the Na~+-K~+-ATPase content of the rice-fried Codonopsis pilosula group was lower(P<0.05),and the content of AQP 3 was higher,but there was no significant difference(P>0.05).4.Analysis of the difference of intestinal flora between Codonopsis pilosula and different rice-fried Codonopsis pilosulaA total of 1,800,324 valid sequences and 48,232 OTUs were obtained from 30samples in 5 combinations.The results of principal component analysis(PCA),principal coordinate analysis(PCo A)and non-metric multidimensional scaling analysis(NMDS)based onβdiversity distance show the intestinal flora of rats in the blank group and the model group,the model group and the three administration groups There are obvious differences in composition;at the phylum level,the dominant flora of the 5 groups are Firmicutes,and the secondary dominant flora is Bacteroides;at the genus level,the dominant flora of the 5 groups are Lactobacillus,The secondary dominant flora is the Mycobacterium spp.There is no significant difference in the microbial structure and relative abundance between the millet-fried Codonopsis pilosula group and the rice-fried Codonopsis pilosula group.Conclusion:There is a certain difference between the main chemical composition content of Codonopsis pilosula and the overall chemical composition shown by the fingerprint spectrum of fried rice.Stir-fried Codonopsis pilosula with large and small rice has a certain improvement effect on rats with spleen deficiency,but both have their own advantages in regulating indicators.Among them,fried Codonopsis pilosula with rice is more helpful in regulating the function of the digestive tract and maintaining the integrity of the digestive tract structure.It helps to enhance the immune function of rats with spleen deficiency;the millet-fried Codonopsis pilosula is more helpful to regulate the water metabolism of spleen-deficiency rats.At the same time,Codonopsis pilosula and rice-fried Codonopsis pilosula can regulate the intestinal flora of spleen-deficiency rats. |
