Abstract: The components of Campsis radicans (L.) Seem.were separated by means of repeated chromatography on silica gel,ODS,Amberchrom CG161M and Sephadex LH20.Their structures were identified on the basis of spectroscopic analysis and chemical evidence.Fourteen compounds were isolated and identified as uvqol (1),3 βhydroxy18,19 αurs20en28oic acid (2),ursolic acid (3),oleanolic acid (4),19 αhydroxyursolic acid (5),hederagenin (6),maslinic acid (7),corosolic acid (8),tormentic acid (9),euscaphic acid (10),rotundic acid (11),arjunglucosideⅡ (12),rengyolone (13),(3αR)hexahydro3αhydroxybenzofuran6 (2 H)one (14).Compunds 1,2 and 5~14 were isolated from this plant for the first time.Compunds 1,2,5,10~12 and 14 were isolated from the Campsis for the first time.

Key words: Campsis radicans (L.) Seem., triperpenoids, structural identification
