英文摘要: In order to evaluate the quality of maca samples, 15 batches of maca hypocotyls from different geographical origins were analyzed by using HPLC and liquid chromatography tandem mass spectrometry (LC-MS). Their glucosinolates (GLs) were identified, profiled, and quantified. Three aromatic GLs, glucosinalbin (GSB), glucotropaeolin (GTL), and glucolimnanthin (GLH), were identified from maca roots. It was found that the HPLC profiles of maca samples showed a similar qualitative pattern except for some differences in their contents. The amount ranges (μmol g−1, DW) of GSB, GTL, and GLH were 2.62–5.55, 12.99–57.12, and 3.15–12.12, respectively. Furthermore, a HCA (hierarchical clustering analysis) was used to classify the quality of maca samples according to their cultivated sources...
