The content of five alkaloids, scopolamine, hyoscyamine, anabasine, nornicotine and nicotine, in the seedlings of Duboisia myoporoides was determined at various intervals during the first year of growth. The total alkaloid content in the leaves was much greater than those in the stems or the roots at all the stages examined. Cotyledons contained only a trace amount of anabasine and nornicotine. The foliage leaves contained four of the five alkaloides, i.e. scopolamine, anabasine, nornicotine and nicotine, at 2-month old stage and all the five alkaloides after 6-month old stage. Scopolamine and hyoscyamine content increased as the plant grows. Anabasine and nornicotine always constituted main alkaloid. Nicotine content reached its maximum at 4-month old stage, then decreased to a lower value and after that remained constant at that level.
