The phytochemistry of both bulbs and seeds of the ethnomedicinal Crinum stuhlmannii subsp. delagoense (Amaryllidaceae) was studied, sourced from a single location simultaneously. Eight alkaloids, including two previously unreported ones, N-methyl-haemanthamide (nivanine), and N-methyl-ent-delagoenine, were isolated along with lycorine, 8,9-methylenedioxophenanthridine, 6-hydroxycrinamine, 6-ethoxycrinamine, haemanthamine and hamayne. Compounds isolated were tested for acetylcholinesterase inhibition. (C) 2020 SAAB. Published by Elsevier B.V. All rights reserved.
