Four flavonoids have been isolated from the leaves and stems of Cudrania tricuspidata Bureau (Moraceae) in Korea. They were kaempferol and kaempferol $7-O-{eta}-D-glucopyranoside$ from the leaves, and kaempferide $7-O-{eta}-D-glucopyranoside$ and naringenin $7-O-{eta}-D-glucopyranoside$ from the stem respectively. The structures were established by spectroscopic and chemical methods.
