  Flavonol glycosides from Chenopodium foliosum Asch

  摘要：

  Three new flavonol glycosides, namely 6-methoxykaempferol-3-O-beta-gentiobioside, gomphrenol-3-O-beta-gentiobioside and gomphrenol-3-O-alpha-L-rhamnopyranosyl-(1 -> 2)[beta-D-glucopyranosyl-(1 -> 6)]-beta-D-glucopyranoside as well as the known patuletin-3-O-beta-gentiobioside and spinacetin-3-O-beta-gentiobioside were isolated from the aerial parts of Chenopodium foliosum Asch. The structures of the compounds were determined by means of spectroscopic methods (1D and 2D NMR, UV, IR, and HRMS). DPPH free radical scavenging activity of the new compounds was low or lacking.
