Corydalis remota Fish. ex Max. (Papaveraceae) is a well known medicinal plant being used as analgesics or anticonvulsive in oriental medicine. As the alkaloid content is known to vary depending on the environmental factors, the technology of plant tissue culture can be adopted as source of Corydalis-alkaloids. The present study describes an establishment of tissue cultures of Corydalis which produce alkaloids consistently. Callus were induced from immature seeds of Corydalis remota by placing the seeds on MS static media containing NAA(0.25, 1.0 and 4.0 mg/l, respectively). The combined treatment of NAA(1.0 mg/l) with cytokinin(BAP 0.5 mg/l) improved the induction of callus. TLC scanning data followed by sequential extraction and purification revealed that the induced callus contains a significant amount of alkaloids. Cell suspension cultures were established by transferring the induced callus into the liquid media with the same condition of plant growth regulators as the callus culture.
