Abstract

The stem barks of Kalopanax septemlobus were extracted with MeOH, and successively partitioned with $CH_2Cl_2$, EtOAc, BuOH and water. Repeated column chromatographic separation of the $CH_2Cl_2$ fraction resulted in the isolation of four compounds. Their structures were identified as ${\beta}-sitosterol$ (1), oleanolic acid (2), 3,3'-bis(3,4-dihydro-4-hydroxy-6-methoxy-2H-1-benzopyran) (3) and (-)-balanophonin (4). This is the first report on the isolation of 3,3'-bis(3,4-dihydro-4-hydroxy-6-methoxy-2H-1-benzopyran) (3) and (-)-balanophonin (4) from Kalopanax spp.
