In the course of screening for pharmacologically active substances from extracts of crude drugs used traditionally in Sino-Japanese herbal medicines, it was found that the 70 % ethanol extract from the fruits of Arctium lappa L. (Compositae) showed potent antiproliferative activity against B cell hybridoma cell, MH60. By bioassay-guided purification, a new lignan, (+)-7,8-didehydroarctigenin, together with the known lignans (-)-arctigenin and (-)-matairesinol were isolated as the active ingredients from an aqueous ethanolic extract of the fruits of A. lappa. Of these active compounds, (-)-arctigenin showed the most potent antiproliferative activity against MH60 cells (IC (50) : 1.0 microM), and the activity was suggested to be due to apoptosis.
