Abstract

Galanthamine, an isoquinoline alkaloid acetylcholinesterase inhibitor, is an important agent used all around the world for the symptomatic treatment of senile dementia of the Alzheimer’s type. The production of this metabolite and the availability of the plant are limited and prompted the search for an alternative way to obtain this valuable metabolite using in vitro cultures of Leucojum aestivum L. It is known that cell differentiation level shows a major influence upon the accumulation of alkaloids. For this reason, tissue cultures of L. aestivum showing different stages of morphogenesis controlled by exogenous growth regulators were established. Agrobacterium rhizogenes strain LBA 9402 has been tested for its capacity to induce hairy roots of this monocotyledonae plant.
