Two flavonoid glycosides identified as flavone 4'-hydroxy-3',5,5'-trimethoxy-7-O-β-D-glucopyranosyl(1\(\rightarrow\)4)-α-L-rhamnopyrailoside (1) and flavone 3',4'-dihydroxy-6-methoxy-7-O-α-L-rhamnopyranoside (2) with three known compounds β-sitosterol, β-sitosterol-β-D-glucopyranoside and quercetin have been isolated from the leaves of Myrica esculenta. Their structures were elucidated on the basis of spectroscopic evidences and chemical studies.
