Immature bitter orange fruit and its extracts have been introduced into the market as an alternative to Ephedra in weight loss products. However, the safety of the immature bitter orange fruit and its extracts is a debated argument due to the presenc

The mass spectrometric behaviour of two couples of stereoisomeric compounds, intermediates in the stereocontrolled synthesis of protoberberines, has been studied by means of electrospray ionization (ESI), atmospheric pressure chemical ionization (APC

The behaviour of di- and tri-fluorinated-ephedrines and -norephedrines has been studied by fast atom bombardment, atmospheric pressure chemical ionisation (APCI) and electrospray ionisation (ESI) experiments and compared with that of the unfluorinate

Unsaturated 5(4H)-oxazolones lead, by methanolysis, to the corresponding dehydroamino acid derivatives. Interestingly, under atmospheric pressure chemical ionisation (APCI) conditions, the latter give rise, aside from abundant [M+H]+ ions, to [MHCH3O
