Analysis of Chemical Constituents in Oroxyli Semen by UPLC-Q-TOF-MS
had a variety of pharmacological effects against inflammation
infections
and oxidation. In this study
an ultra-high performance liquid chromatography (UPLC-Q-TOF-MS) method was established to analyze and identify the various flavonoids in Oroxyli Semen.
Method:
2
The separation was performed on an Kinetex-XB C
18
column(2.1 mm × 50 mm
1.7 μm)with gradient elution
which was carried out with 0.1%formic acid acetonitrile as mobile phase. The flow rate was 0.25 mL·min
-1
and the injection volume was 3 μL. Electrospray ionization source was in the negative ion mode. Target and non-target screenings were carried out by Peakview 2.2 and Masterview 1.0 software. Then the identification of target compounds were completed based on accurate mass
isotopic abundance ratio and MS/MS fragment
and the non-target compounds were determined according to literature reports and MS cleavage mechanism.
Result:
2
According to the high resolution MS spectra data
fragmentation ion information and retention time
36 peaks of Oroxyli Semen were identified
including 10 flavonoids and 26 flavonoid glycosides according to literature reports and MS cleavage mechanism.
Conclusion:
2
The study comprehensively analyzes the chemical composition of Oroxyli Semen
which is significant to study of the chemical constituents
quality control and material basis of Oroxyli Semen.
