Ultra performance liquid chromatography coupled with quadrupole/electrostatic field orbital trap high resolution mass spectrometry(UHPLC-Q Exactive Focus MS/MS)method was developed to rapidly analyze and identify the alkaloids from Shaanxi-produced crude Fuzi(Aconiti Lateralis Radix Praeparata).
The chromatographic separation was performed on the Waters Acquity UPLCBEH C18 column(2.1 mm×50 mm,1.7 μm)with acetonitrile-0.1% formic acid water solution as themobile phase for gradient elution. The electrospray ion source(ESI)was adopted to collect the data in positive ionization modes,and the detection range was m/z 100~1500.
The chemical constituents were identified and confirmed by analyzing themass data from the reference substances and literature. A total of 228 alkaloidswere identified,including 21 C18 alkaloids,145 C19 alkaloids[42 diester diterpenoid alkaloids(DDAs),47 monoester diterpenoid alkaloids(MDAs),42 aminoalcohol-diterpenoid alkaloids(ADAs),14 lipo alkaloids(Lipo-As)],27 C20 alkaloids and 35 others,28 of them were discovered for the first time.
The establishedmethod systematically analyzed the alkaloids of Shaanxi-produced crude Fuzi(Aconiti Lateralis Radix Praeparata). It provides a reference for the subsequent study ofmaterial basis and developmentof Shaanxiproduced crude Fuzi(Aconiti Lateralis Radix Praeparata).
