The content of atropine and scopolamine is known to vary with ontogeny and plant organs selected which makes it necessary to define the optimal stage for harvesting of each plant organ. The present study aims at investigating the effect of ontogeny on the accumulation of atropine and scopolamine in the leaves, stems, roots, flowers and fruits of the Solanaceae plants Bercht. & J.Presl, L. L., Mill. and L. Results showed that the highest content of atropine and scopolamine was observed during the flowering stage of most organs. L. leaves collected during flowering stage exhibited the highest content of atropine (746.66 ug/g) followed by the pre-flowering leaves of L. and the flowering stage stems of L. while Mill. pre-flowering leaves and flowering stems had significantly higher content of scopolamine among all the tested extracts with a concentration of 555.04 ug/g and 244.26 ug/g, respectively.
