- 50 Downloads
Two new lignans, dolichanthin A (1) and dolichanthin B (2), were isolated from the EtOAc extract of Wikstroemia dolichantha. Their structures were elucidated by the analysis of 1D and 2D spectroscopic data as well as MS. The inhibitory activity of two isolates against acetylcholinesterase (AChE) revealed that compound 1 exhibited weak inhibitory activity.
