Effect of L-dopa and L- methionine supplementation on bioproduction of ementine in callus cultures of cephaelis ipecacuanha.

Callus cultures were induced from leaf segments of Cephaelis ipecacuanha on modified gamborg medium containing 2,4 - dichlorophenoxy acetic acid (2mg/1) Indole acetic acid (1mg/1), kinetin (1mg/1) and sucrose (20g/1). The biogenetic profile for alkaloids was established. The established callus cultures were transferred to modified gamborg medium supplemented with L- DOPA (40 mg/1) and L methionine (3mg/1).
