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: 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.

Key words: Acanthopanax Senticosus Harms, Flavonoid, Electrospray tandem mass spectrometry (ESI-MSn), NMR
