Abstract:
Objective:To quickly analyze and identify the components in raw and wine-processed products of Polygonatum cyrtonema （PC） dried rhizomes by ultra-high performance liquid chromatography-quadrupole-time-of-flight mass spectrometry （UPLC-Q-TOF-MS）， and then find out the differential components before and after processing. Method:The ACQUITY UPLC BEH C18 column （2.1 mm×100 mm， 1.8 μm） was used with 0.1% formic acid aqueous solution-acetonitrile as the mobile phase for gradient elution at a flow rate of 0.25 mL·min-1. Electrospray ionization was selected for collection and detection in positive and negative ion modes， and the data were analyzed by PeakView 1.2.0.3. According to the retention time， accurate relative molecular weight and fragmentation ion information provided by MS， and combined with the reference substance and literature， the components were identified. After normalized treatment， the MS data of each sample were analyzed with principal component analysis （PCA） and orthogonal partial least squares-discriminant analysis （OPLS-DA）， and then the differential components before and after processing were screened according to the principle that variable importance in the projection （VIP） value was >1. Result:A total of 38 components were identified from raw and wine-processed products of PC dried rhizomes， including 15 steroidal saponins， 6 alkaloids， 3 flavonoids， 2 amino acids， 2 organic acids and 10 others. The results of PCA and OPLS-DA showed that there were significant differences in the contents of components in PC dried rhizomes before and after processing， and 16 differential components such as kingianoside Z， disporopsin and linoleic acid were screened. Conclusion:UPLC-Q-TOF-MS technique can accurately and comprehensively identify the components in PC dried rhizomes， these components are mainly steroidal saponins， flavonoids and alkaloids. It takes a great difference in the contents of components before and after processing， and transformation of the same category components is the main reason for the differences of raw and wine-processed products， which will provide reference for the researches on material basis and processing chemistry of PC dried rhizomes.
