title: New caffeoyl derivatives from the leaves of Davidia involucrata.
abstract: Three new caffeoyl galactoic acid derivatives, davidiosides A-C (1-3) together with four known caffeoyl derivatives such as: caffeic acid (4), methyl caffeate (5), chlorogenic acid (6), and methyl chlorogenate (7) were isolated from the leaves of Davidia involucrate. The new structures were determined by spectroscopic data and chemical evidence.
