Production of emetic alkaloid by in vitro culture of cephaelis ipecacuanha A. Richard
Tóm tắt
Callus and adventitious roots were induced on leaf segments from shoot culture of Cephaelis ipecacuanha A. Richard on Murashige-Skoog medium containing 2,4-dichlorophenoxyacetic acid, indole-3-acetic acid, 1-naphthaleneacetic acid and kinetin. The contents of emetic alkaloids in calli, roots and root suspension cultures were quantified by HPLC. Roots cultured in solid and liquid Murashige-Skoog media yielded emetine and cephaeline. The amount of the two alkaloids in the root suspension culture was very similar to that of roots from ipecac mother plant grown in a greenhouse. In contrast, calli subcultured on Murashige-Skoog media containing combinations of 2,4-dichlorophenoxyacetic acid and kinetin produced only trace amounts of emetic alkaloids.
