In order to survey possibility to produce saikosaponin from in vitro hairy root culture, culture of callus, adventitous root, and hairy root of Bupleurum falcatum L. were estabilished, and quantitative and qualitative aspects in saikosaponin extracted from thses were compared with those of cultivated root. Callus grew well in MS medium containing 0.9 ㎛ 2,4-D. In contrast, both of adventitous root and hairy root grew well in hormone-free MS medium. However, hairy root showed more rapid growth with extensive lateral root branches, characteristics of lower content of water and softer than in adventitous root. Among the selected lines of adventitous root and hairy root were observed difference in the growth rate. Mannopine, one of opine synthesized in the transformed tissue with Agrobacterium rhizogenes A_4 were detected in the extract of hairy root lines. Pattern and content of crude saponin from adventitous and hairy root showed no difference, but somewhat difference from those of cultivated root. However, in callus, distinct production-aspect of saponin was not observed.
