Abstract

Campsis grandiflora K. Schum. flower was extracted with 80% aqueous MeOH, and concentrated extract was successively partitioned with EtOAc, n-BuOH, and $H_2O$. From n-BuOH fraction, two cyclohexylethanoids were isolated through repeated silica gel and Sephadex LH-20 column chromatographies. Based on physico-chemical data obtained from NMR, MS, and IR, chemical structures of compounds were determined as 1,4-dihydroxy-3,4-(epoxyethano)-5-cyclohexene (1) and cornoside (2). These compounds were isolated for the first time from C. grandiflora K. Schum flower.
