To comprehensively profile plant APOs, we established an improved ultra-high performance liquid chromatography-hybrid quadrupole-Orbitrap mass spectrometer (UHPLC-Q-Orbitrap MS) analytical platform. 
UHPLC-Q-Orbitrap MS
The improved APO analytical platform consists of an optimized sequential APO sample preparation and multiple UHPLC-MS detection methods and was successfully used to identify and quantify multiple subclasses of APOs from tomato fruits.  In addition, multiple UHPLC-MS detection methods enables high throughput analysis of APOs.
