title: Simultaneous Determination of 16 Nucleosides and Nucleobases in Euryale ferox Salisb. by Liquid Chromatography Coupled with Electro Spray Ionization Tandem Triple Quadrupole Mass Spectrometry (HPLC-ESI-TQ-MS/MS) in Multiple Reaction Monitoring (MRM) Mode.
abstract: In this study, a simple, rapid, efficient analytical method was established for the qualification and quantification of 16 nucleosides and nucleobases in Euryale ferox Salisb. by using liquid chromatography coupled with electrospray ionization tandem triple quadrupole mass spectrometry (HPLC-ESI-TQ-MS/MS) in multiple-reaction monitoring (MRM) mode. Ideal separation of 16 target compounds was achieved on Xbridge Amide HILIC column (4.6 × 150 mm, 3.5 μm) with gradient elution in 11 min by optimized conditions. Variations of nucleosides and nucleobase in samples from different cultivation regions ranging from 190.50 to 1594.30 μg/g were obvious. The total nucleoside contents were higher than total nucleobases, especially in the compositions of guanosine, cytidine and 2'-deoxyguanosine. Samples 1-18 with dense thorns were better characters than samples 19-26 without thorns in terms of nucleosides and nucleobases concentrations in general. The limits of detection (LODs) and quantification (LOQs) for 16 analytical substances were investigated to be 0.11-6.33 ng/mL and 0.35-21.1 ng/mL, respectively. And the method was first applied to large aquatic plants with good linearity, precision, repeatability and accuracy. All present information provided a scientific and rational reference for quality assessment and control of Euryale ferox Salisb.
