Nine known compounds: trans-cinnamic acid, catechin, syringin, epicatechin, symplocoside, kaempferol 3-O-rhamnoside 7-O-glucoside, isovitexin 2-O-rhamnoside, herbacetin 7-O-glucoside, and pollenitin B and a new flavonoid glycoside, characterized as herbacetin 7-O-neohesperidoside (1) on the basis of spectroscopic analysis and chemical evidence, were isolated from a traditional crude drug, Ephedra herb extract . Compound 1 had no effects on HGF-induced motility, whereas herbacetin, which is an aglycone of 1, significantly inhibited it.

The new quercetin 3-6)-β-D-glucoside> has been isolated together with the dihydroflavonol glucoside callunin and quercetin 3-α-L-arabinoside.Structural elucidation of these natural products was achieved mainly by 1H and 13C NMR spectroscopy.Furthermore, 1H NMR assignments for H-2 and H-3 of the dihydroflavonol glucoside were interchanged. Key Word Index - Calluna vulgaris; Ericaceae; flowers; 5,7,8,4'-tetrahydroxydihydroflavonol 8-glucoside; callunin; quercetin 3-α-L-arabinoside; quercetin 3-6)-β-D-glucoside>; acylated flavonoid glycosides.

Major phenolic compounds in the shoots of Calluna vulgaris were chlorogenic acid, the 3-O-glucoside, 3-O-galactoside and 3-O-arabinoside of quercetin, (+)-catechin, procyanidin D1 and a newly identified phenolic glycoside, 3,5,7,8,4'-pentahydroxyflavanone 8-O-glucoside (callunin).Roots contained only (+)-catechin and procyanidin D1 in high quantities.Smaller amounts of other phenolic compounds were present in both shoot and root.The number and the quantity of these substances were much higher in the summer months than in winter. - Key Word Index:Calluna vulgaris; Ericaceae; phenolic acids; flavonoids; new dihydroflavonol glycoside; callunin; seasonal variation.
