Isolated from the whole plants of Leucas urticifolia, it exhibits cholinesterase inhibitory activity. It has a role as a metabolite and an EC 3.1.1.8 (cholinesterase) inhibitor. It is a member of phytosterols, a 3beta-sterol, a tertiary alcohol and a 3beta-hydroxy-Delta(5)-steroid. It derives from a hydride of a stigmastane."}]
