Flavonoids from the leaves of Betula platyphylla var. latifolia.[Reference: WebLink]

METHODS AND RESULTS:
Chemical examination of the leaves of Betula platyphylla var. latifolia has led to the isolation and characterization of five flavonoid glycosides including two C-glucosyl flavonoids. The structures of these compounds were elucidated as myricetin 3-O-α-L-rhamnoside (myricitrin), quercetin-3-O-β-D-glucopyranoside (isoquercitrin), quercetin-3-O-β-D-galactopyranoside (hyperoside), nalingenin-6-C-β-D-glucopyranoside (Hemiphloin) and aromadendrin-6-C-β-D-glucopyranoside (6-C-glucosyldihydrokaempferol) on the basis of physico-chemical and spectroscopic evidences.
