Chemical investigation of the n-BuOH-soluble fraction of the EtOH extract of the aerial part of Curcuma longa led to the isolation of 11 flavonol glycosides and one dihydroflavonol glucoside (1) via chromatography over Sephadex LH-20 and Lobar RP-18 columns. Although they are known, the 1H and 13C NMR data recorded in CD3OD rather than the common DMSO-d6 are doubly checked via extensive 2D NMR spectroscopic analyses, leading to some revisions of the reported data, especially for the glycon part.
对姜黄地上部分乙醇提取物的正丁醇可溶部分进行化学研究，通过葡聚糖凝胶LH - 20柱色谱和Lobar RP - 18柱色谱分离得到了11种黄酮醇苷和1种二氢黄酮醇葡萄糖苷（1）。尽管这些化合物是已知的，但在CD3OD而非常用的DMSO - d6中记录的1H和13C NMR数据通过广泛的二维NMR光谱分析进行了双重核对，从而对报道的数据进行了一些修正，尤其是对于糖苷部分。
