摘要：

Three new flavonoids were isolated from the dried leaves of Licania densiflora (synonymous Licania kanukuensis). Their structures were elucidated as 8-hydroxy-naringenin-4'-methyl ether, myricetin 3',4'-dimethyl ether 3-O-beta-D-glucopyranoside, and myricetin 3-O-alpha-L-(2 "-O-alpha-L-rhamnopyranosyl)-rhamnopyranoside by means of spectral data.
