Characterization of protostane triterpenoids in Alisma orientalis by ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry

04-May-2010 | Xin Liu, Song-Lin Li, Yan Zhou, Jing-Zheng Song, Yun-Feng Zheng, Guo-Ping Peng, Hong-Xi Xu, Rapid Communications in Mass Spectrometry, 2010

A reliable and sensitive ultra-performance liquid chromatography/quadrupole time-of-flight mass spectrometry (UPLC/Q-TOF-MS) method has been optimized and established for analysis of protostane triterpenoids in a commonly used traditional Chinese herbal medicine Alisma orientalis (Sam.) Juzep. ...

A nuclear magnetic resonance (1H and 13C) and isotope ratio mass spectrometry ([delta]13C, [delta]2H and [delta]18O) study of Andalusian olive oils

15-Apr-2010 | María A. Aramendía, Alberto Marinas, José M Marinas, Elena Sánchez, Francisco J. Urbano, Claude Guillou, José M. Mor ..., Rapid Communications in Mass Spectrometry, 2010

We have determined [delta]13C, [delta]2H and [delta]18O isotopic abundances in Andalusian olive oils. In addition, the fatty acid composition and the distribution of isomers at positions 1,3 and 2 of glycerol were determined by 1H and 13C nuclear magnetic resonance (NMR) spectroscopy, ...
