Objective:
To analyze the styryllactone components in Goniothalamus cheliensis Hu (Annonaceae).
Method:
UPLC-Q-TOF-MS was used to identify the main styryllactone components in G. cheliensis. The chromatographic separation was performed on ACQU ITY UPLC BEH C18 column and eluted by actonitrile and 0.1% acetic acid in water gradiently. The mass spectrometer equipped with electrospray ionization souce was used as detector under the positive ion modes.
Result:
Twelve styryllactons were identified based on their MS data and published literatures, and the MS fragmentation regularity of the styryllactones was also proposed.
Conclusion:
It is an accurate and effective method to obtain the structural information of styryllactones.
