摘要： BACKGROUND: Macamides with a benzylalkylamide nucleus are characteristic and major bioactive compounds in the functional food maca(Lepidium meyenii Walp). The aim of this study was to explore variations in macamide content among maca from China and Peru. Twenty-seven batches of maca hypocotyls with different phenotypes, sampled from different geographical origins, were extracted and profiled by liquid chromatography with ultraviolet detection/tandemmass spectrometry (LC-UV/MS/MS).
