  Flavonoid and benzophenone glycosides from Coleogyne ramosissima

  摘要：

  A benzophenone glucoside and two flavonol glycosides were isolated together with 27 known polyphenols from the aerial parts of Coleogyne ramosissima, and their structures were elucidated by spectroscopic and chemical methods as iriflophenone 2-O-beta-glucogyranoside, isorhamnetin 3-O-2(G)-rhamnopyranosylrutinoside-7-O-alpha-rhamnopyranoside and limocitrin 3-O-rutinoside-7-O-beta-glucopylanoside, respectively.
