GNPS_Euphorbia amygdaloides ssp. semiperfoliata (Corsican Euphorbiaceae plant)

ABSTRACT: Euphorbia amygdaloides ssp. semiperfoliata, LC-MSn analysis of AcOEt plant extract, and 12 references MS2 spectra of diterpene esters. Fragmentation behavior of diterpene esters (jatrophane type) had been studied by multiple stage mass spectrometry. The AcOEt showed very potent antiviral activity (against chikungunya virus and HIV).

This paper reports our effort to develop a comprehensive HPLC-MS(n)-based dereplication strategy for phorbol ester (PE), deoxyphorbol ester (dPE) and ingenol ester (IE) profiling in plant extracts. This strategy is composed of two sequential analysis exploiting specific hybrid triple quadrupole/linear ion trap instrument modes. A first run was performed using a multiple reaction monitoring (MRM) mode targeting fragmentation of PE and dPE/IE coupled with the acquisition of MS(2) spectrum for the  ...[more]
