Direct olive oil analysis by low-temperature plasma (LTP) ambient ionization mass spectrometry.

29 Sep 2009 A fast, reagentless, and direct method is presented for the mass spectrometric analysis of olive oil without any sample pretreatment whatsoever. An ambient ionization technique, the low-temperature plasma (LTP) probe, based on dielectric barrier ... Read more...

A novel approach to the rapid assignment of (13)C NMR spectra of major components of vegetable oils such as avocado, mango kernel and macadamia nut oils.

30 Aug 2009 Assignment of (13)C nuclear magnetic resonance (NMR) spectra of major fatty acid components of South African produced vegetable oils was attempted using a method in which the vegetable oil was spiked with a standard triacylglycerol. This proved to ... Read more...

Minor furanocoumarins and coumarins in grapefruit peel oil as inhibitors of human cytochrome P450 3A4.

30 Aug 2009 A new cyclic acetal (1) of marmin (6',7'-dihydroxy-7-geranyloxycoumarin), two new cyclic acetals (5, 6) of 6',7'-dihydroxybergamottin, and the known compounds marmin (2), 7-geranyloxycoumarin (3), bergamottin (4), and 6',7'-dihydroxybergamottin (7) ... Read more...
