Abstract
Abstract Two new esters identified as 1-ethyl 7-(4-octyl-5-oxocyclopenta-1,3-dien-1-yl) heptanedioate (1) and ethyl (7E,9E)-6-oxooctadeca-7,9-dienoate (2) were isolated from the aerial parts of Portulaca oleracea L. The new structures were determined by using high-resolution electrospray ionization time-of-flight mass spectrometry, and 1D, 2D NMR. Furthermore, the compounds presented anticholinesterase effects with IC50 values of 63.87 ± 0.54 μM and 64.71 ± 0.25 μM, respectively.
