6-Methoxyflavonol Glycosides with In Vitro Hepatoprotective Activity from Chenopodium Bonus-henricus Roots

One new, namely 6-methoxykaempferol 3- O-[β-apiofuranosyl(1→2)]-β-glucopyranosyl(1→6)-β-glucopyranoside (2), and two known flavonoid glycosides, spinacetin 3- O-[β-apiofuranosyl(1→2)]-β-glucopyranosyl(1→6)-β-glucopyranoside (1) and spinacetin 3- O-gentiobioside (3), were isolated from the roots of Chenopodium bonus-henricus L. Their structures were determined by means of spectroscopic methods (1D, 2D NMR, UV, IR) and HR-ESI-MS. Radical...
