[Analysis of styryllactones from Goniothalamus cheliensis by UPLC-Q-TOF-MS].

OBJECTIVE

To analyze the styryllactone components in Goniothalamus cheliensis Hu (Annonaceae).

METHODS

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.

RESULTS

Twelve styryllactons were identified based on their MS data and published literatures, and the MS fragmentation regularity of the styryllactones was also proposed.

CONCLUSIONS

It is an accurate and effective method to obtain the structural information of styryllactones.
