The present work was designed to compare four commercial samples of quercetin, three of them presenting pharmaceutical grade (QPGa, QPGb and QPGc) and the other one pro-analysi grade (QPA) by means of different techniques. Physical and chromatographic characterization of these samples shows different properties following its origin, especially a clear evidence of polymorphism occurrence.
本研究旨在通过不同技术比较四种槲皮素商业样品，其中三种为药用级（QPGa、QPGb和QPGc），另一种为分析纯级（QPA）。这些样品的物理和色谱表征显示出其来源不同的特性，特别是明显存在多态性的证据。
