Abstract
The process of alkaloid biosynthesis by Pancratium maritimum shoot culture, cultivated under submerged conditions, was investigated. Twenty-two compounds of different structural types of the Amaryllidaceae alkaloids (tyramine, narciclasine, galanthamine, haemanthamine, lycorine, pancracine, tazettine and homolycorine types) were detected in the studied samples from biomass and cultural liquid. Dominant compounds in the shoots were of tyramine, lycorine and haemanthamine types, whereas in the culture media were found mainly lycorine type compounds. Based on the multi-metabolic estimation of the alkaloid metabolism and physiological peculiarities, liquid cultures of P. maritimum shoots could be defined as prospective biological systems for producing bioactive molecules with acetylcholinesterase inhibitory and apoptotic activities.
