THE FLAVONOIDS OF ALLIUM-URSINUM

From wild garlic Allium ursinum three new flavonoid glycosides were id entified as kaempferol ta-neohesperidoside-7-O-[2-O-(trans-p-coumaroyl )]- beta-D-glucopyranoside, kaempferol 7-O-[2-O-(trans-feruloyl)]-beta -D-glucopyranoside, kaempferol eta-neohesperidoside-7-O-[2-O-(trans-p- coumaroyl)- 3-O-beta-D-glucopyranosyl]-beta-D-glucopyranoside and char acterized as the peracetates. Additionally, two known flavonoid glycos ides kaempferol 3-O-beta-glucopyranoside and kaempferol 3-O-beta-neohe speridoside were isolated. The isolated compounds showed an inhibition of human platelet aggregation.
