From wild garlic Allium ursinum three new flavonoid glycosides were identified as kaempferol 3-O-β-neohesperidoside-7-O-[2-O-(trans-p-coumaroyl)]-β-D- glucopyranoside, kaempferol 3-O-β-neohesperidoside-7-O-[2-O-(trans-feruloyl)]-β-D-glucopyranoside, kaempferol 3-O-β-neohesperidoside-7-O-[2-O-(trans-p-coumaroyl)-3-O-β-D- glucopyranosyl]-β-D-glucopyranoside and characterized as the peracetates. Additionally, two known flavonoid glycosides kaempferol 3-O-β-glucopyranoside and kaempferol 3-O-β-neohesperidoside were isolated. The isolated compounds showed an inhibition of human platelet aggregation.

Abstract
From wild garlic Allium ursinum three new flavonoid glycosides were identified as kaempferol 3-O-β-neohesperidoside-7-O-[2-O-(trans-p-coumaroyl)]-β-D- glucopyranoside, kaempferol 3-O-β-neohesperidoside-7-O-[2-O-(trans-feruloyl)]-β-D-glucopyranoside, kaempferol 3-O-β-neohesperidoside-7-O-[2-O-(trans-p-coumaroyl)-3-O-β-D- glucopyranosyl]-β-D-glucopyranoside and characterized as the peracetates. Additionally, two known flavonoid glycosides kaempferol 3-O-β-glucopyranoside and kaempferol 3-O-β-neohesperidoside were isolated. The isolated compounds showed an inhibition of human platelet aggregation.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
