The alkaloid contents in the seeds of nine species of the genus Datura were measured by GC. The ratios of the hyoscyamine content to the scopolamine content, and their amount were compared. The seeds of D. metel, D. meteloides and D. fastuosa contained more scopolamine than hyoscyamine. However, in D. innoxia, the hyoscyamine content was higher than or equal to the scopolamine content. D. stramonium and its varieties, var. tatula, var. inermis, var. godronii, and D.ferox contained mainly hyoscyamine, and their ratios of the hyoscyamine contents to the scopolamine contents were about the same. The results agree with those on the ovaries alkaloidamp the previously reported. It was shown that the section Datura plants differ from the section Stramonium plants in the alkaloid composition of the seeds.
