Calli cultures derived from Ruscus aculeatus rhizomes were investigated for their potential to biosynthesize saponins. The capacity of undifferentiated tissues to form steroidal saponins is very limited, but when the calli developed organogenesis, mainly aerial shoots and roots, the saponin production increased significantly. Plantlets regenerated from aerial shoots of Ruscus calli showed a saponin pattern similar to that of the callus cultures but the levels of saponins found in the aerial part and roots were significantly greater.
