Quantitative Assessment of Hyoscyamine and Scopolamine Tropane Alkaloids in Root and Shoot of Hyoscyamus spp. from Iran

Journal of Medicinal Plants, 2015
Background: Different species of Hyoscymaus are rich sources of tropane alkaloids, especially hyoscyamine and scopolamine. These compounds medicinally are important tropane alkaloids that exclusively are produced by plants.
