Key Word Index - Campsis chinensis; Bignoniaceae; bitter phenyl propanoid glycosides; R,S-β-methoxy-β-(3',4'-dihydroxyphenyl)-ethyl alcohol; R,S-β-hydroxy-β-(3',4'-dihydroxyphenyl)-ethyl alcohol; caffeic acid; acteoside; campneoside I; campneoside II.A new bitter phenyl propanoid glycoside, campneoside I, was isolated, together with acteoside and campneoside II, from the leaves of Campsis chinensis.The stereostructure of campneoside I was established as R,S-β-methoxy-β-(3',4'-dihydroxyphenyl)-ethyl-O-α-L-rhamnopyranosyl(1->3)-β-D-(4-O-caffeoyl)-glucopyranoside on the basis of the spectroscopic studies and chemical evidence.
