In China the flowers of the genus Datura plants are used as a cough remedy, spasmolytic and anodyne. As the original plants, D. metel, D. innoxia and other plants are known. We obtained 14 species of plants of the genus Datura and measured the size, the dry weight and the hyoscyamine and scopolamine contents of the flowers collected on different days. The alkaloid contents of the flowers were the highest when they were harvested on the flowering day, and the alkaloid content per flower was generally high in the D. metel, D. innoxia, D. meteloides, D. fastuosa plants, which are section Datura plants. In these section Datura plants, the scopolamine content was higher than the hyoscyamine content. On the other hand, in the case of the section Stramonium plants tested, the flowers were smaller, their alkaloid contents were lower than those of the section Datura plants and their hyosyamine content and the scopolamine content were abou t the same.
