  Six compounds have been isolated from the methanol extract of the aerial parts of Gnidia involucrata (Thymelaeaceae). They were identified as 2,3,4',5,6-pentahydroxybenzophenone-4-C-glucoside and 2,4',6-trihydroxy-4-methoxybenzophenone-2-O-glucoside, together with mangiferin, kaempferol-3-O-glucoside, yuankanin and manniflavanone by chemical and spectroscopic means. The structures of three additional C-glycosyl flavones--vitexin, isovitexin and isoorientin--were determined on-line by LC/UV/APCI-MSn analysis of the crude extract.

  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-β-glucopyranoside, isorhamnetin 3-O-2G-rhamnopyranosylrutinoside-7-O-α-rhamnopyranoside and limocitrin 3-O-rutinoside-7-O-β-glucopyranoside, respectively.
