Change of Alkaloid Distribution in the Regenerated Plants of Duboisia myoporoides During Development

Abstract

The alkaloid composition of regenerated plants from Duboisia myoporoides R. Br. (Solanaceae) callus was determined at various stages of development. Anabasine, nornicotine, scopolamine and hyoscyamine, which are main alkaloids in leaves of the mother plant, were analysed.

The main alkaloids were not detected in the leaves of regenerated plantlets at the early stage of development, but eventually the alkaloid spectrum approached that of the mother plant at the later stage; on the way, various alkaloid spectra were found.

Qualitative and quantitative differences between regenerated plantlets and seedlings with respect to alkaloid distribution were discussed.
