摘要:

利用75%乙醇作为溶剂,采用微波辅助法提取三叶委陵菜黄酮,黄酮样品经D101树脂纯化,采用高效液相色谱分离、串联四极杆质谱负离子方式检测分析。根据相对分子质量、二级质谱碎片、液相色谱保留时间等信息,从三叶委陵菜中测定出了二苯乙烯苷、槲皮素-3,7-芸香糖鼠李糖苷、牡荆素、芦丁、金丝桃苷、橙皮苷、槲皮苷和山奈酚-3-芸香糖苷8种黄酮类成分。

Abstract:

Total flavonoids were obtained from Potentilla freyninan by microwave-assisted extraction method using 75%
ethanol as the extraction solvent and purified with D101 macroporous resin. The purified total flavonoids were analyzed
by high performance liquid chromatography tandem quadrupole mass spectrometry (HPLC-MS/MS) in the negative ion
monitoring mode. Based on relative molecular weight, MS2 fragmentation pattern, and retention time in liquid chromatography,
eight flavonoids in P. freyninan were identified, including 2,3,5,4’-tetrahydroxystilbane-2-O-β-D-glucoside, quercetin-3,7-
rutinosogalactoside, apigenin-8-C-glucoside, rutin, hyperoside, hesperidin, quercitrin, and kaempferol-3-rutinoside.

Key words: Potentilla freyninan, HPLC-MS/MS, flavonoids, hesperidin, hyperoside
