A novel heterodimer of coumaric acid glucoside, polypodiside (1), together with two known caffeic acid derivatives chlorogenic acid (2) and ethyl chlorogenate (3), has been isolated from the Chinese fern Polypodium hastatum. Their structures were determined by various spectroscopic analysis including MS and 1D and 2D NMR (COSY, HMBC, HSQC).
