Abstract
Two new benzoates, asiatoate A (1) and asiatoate B (2), have been isolated from the ethyl acetate soluble fraction of Buddleja asiatica whole plant. Their structures were elucidated with the help of spectroscopic data. Both showed significant inhibitory effect on acetylcholinesterase (AChE) and butylcholinesterase (BChE) in a dose-dependent manner. The IC

values of compounds 1-2 were 5.54 and 8.34 μM against AChE while 30.94 and 35.94 μM against BChE, respectively.
