采用高效液相色谱-光电二极管-质谱联用检测器（HPLC-PDAMS）对鼠李属植物和柄鼠李属植物提取物中的糖基化黄酮醇进行了表征。其主要染料成分为鼠李素-3-O-鼠李糖苷。petiolarls和山奈酚-3-O-鼠李糖苷; utllis。根据这些信息，故宫博物院壁布中使用的黄色染料可以被确定为R petiolaris或一个密切相关的物种。在墙纸（在墙布下面）的情况下，发现的主要黄酮类化合物是芦丁，这表明它是用中国传统使用的染料槐树（Sophora japonica）的芽染色的。本文的研究结果为清末（1840-1912）壁画的复原提供了有价值的信息。除了HPLC-PDA-MS分析外，还使用表面增强拉曼光谱（Sers）来初步鉴定两件历史文物中的黄色染料。从每个清代样品中获得的仅1 mm长的单纤维，需要与染料参考的Sers数据进行比较。这种超灵敏的方法适用于采样仅限于痕量的情况。
Glycosylated flavonols were characterized in the extracts of Rhamnus petiolaris and Rhamnus units, by high performance liquid chromatography coupled with photo diode and mass spectrometric detectors (HPLC-PDAMS). The main dye components are rhamnetin-3-O-rhamninoside for R. petiolarls and kaempferol-3-O-rhamninoside for R. utllis. Based on this information, the yellow dye used in the wall cloth in the Palace Museum can be identified as R petiolaris or a closely related species. In the case of the wallpaper (which was under the wall cloth), the main flavonoid found was rutin, suggesting that it was dyed with buds of pagoda tree (Sophora japonica), a dye traditionally used in China. The results presented here provide valuable information in regard to reconstitution of the late Qing dynasty (1840-1912 AD) wall coverings. In addition to HPLC-PDA-MS analysis, surface enhanced Raman spectroscopy (SERS) was used to tentatively identify yellow dyes in the two historical artifacts. Only a 1 mm length of single fiber, obtained from each Qing dynasty sample, was needed for comparison with the SERS data of dye references. This ultra-sensitive method is suitable for situations where sampling is restricted to trace amounts.
