Researchers identified five new alkaloids and ten known analogues in Lycopodiastrum casuarinoides, a plant commonly used in traditional Chinese medicine to improve cognitive function. Spectroscopic techniques were used to determine the structures of the novel compounds and their absolute configurations. Only huperzine C showed moderate inhibitory activity against acetylcholinesterase, which is associated with Alzheimer's disease. The study highlights the potential of Lycopodiastrum casuarinoides as a source for developing new drugs to treat cognitive impairment.
