Differences in Chemical Composition of Polygonatum cyrtonema Rhizome Before and After Processing Based on UPLC-Q-Exactive Orbitrap MS Analysis增强出版
Ultra performance liquid chromatography-quadrupole-electrostatic field orbitrap high resolution mass spectrometry(UPLC-Q-Exactive Orbitrap MS) was used to analyze the differences in chemical components between raw products and wine-processed products of
Polygonatum cyrtonema
rhizome.
Method
2
UPLC-Q-Exactive Orbitrap MS was used to analyze the chemical compositions of
P. cyrtonema
rhizome before and after processing, and the effective response ions were extracted after raw data processing, and the differential compounds before and after processing were screened combined with multivariate statistical analysis and according to the conditions of variable importance in the projection(VIP) value

0.5, based on the retention time, quasi-molecular ions, fragment ions and other information, the components were identified in combination with the control products and the literature, and the significant difference compounds were identified by clustering thermal analysis and relative quantitative analyzed, in order to clarify the change rule of the main components in
P. cyrtonema
rhizome before and after processing.
Result
2
A total of 72 differential constituents between raw products and wine-processed products were identified, including 15 alkaloids, 12 organic acids, 12 amino acids, 6 flavonoids, 4 saccharides and 23 others. There were a total of 18 significantly different components, among which 13 co
mpounds, including
L
-malic acid, lactic acid and 9,12,13-trihydroxy-10-octadecenoic acid, showed an increasing trend in content after wine processing, 5 compounds such as
trans
-3-indoleacrylic acid,
L
-arginine,
D
-tryptophan, showed a decreasing trend after processing.
Conclusion
2
The chemical components of
P. cyrtonema
rhizome are significantly different before and after processing, mainly organic acids, saccharides, amino acids, flavonoids and alkaloids, which can lay the foundation for the in-depth study of the processing mechanism of Polygonati Rhizoma.
