| 摘 要： | 利用电喷雾质谱发现刺五加叶中存在4种黄酮类化合物，进一步分离得到其中的两种，经核磁质谱鉴定，一种为槲皮甙（槲皮素－3－O－α-L鼠李糖），另一种为金丝桃甙（槲皮素－3－O－β-D-半乳糖），其余两种难以分离的黄酮甙经电喷雾多级串联质谱分析，初步推断为槲皮素和芦丁（槲皮素－3－O－芦丁糖），以上4种均为黄酮醇类化合物，除金丝桃甙外，其它3种为刺五加叶中尚未见报道的黄酮类成分。

| Abstract: | Abstract Four flavonoids from leaves of Acanthopanax Senticosus Harms were observed in negative ion mode in the electrospray mass spectra. Two of them were further isolated and identified as quercitrin (quercetin-3-O- -L-rhamnoside) and hyperin (quercetin-3-O- -D-galactoside) on the basis of MSn and NMR data. The other two compounds in the mixtures were tentatively established as quercetin and rutin ( quercetin-3-O-rutinoside) in terms of their electrospray tandem mass spectrometry (ESI-MSn) data. Three of the four flavonoids (excluding hyperin) haven't been reported in this plant before. |
