Nat Prod Res. 2021 Jan;35(2):350-353. doi: 10.1080/14786419.2019.1627356. Epub 2019 Jun 10.

Abstract

A new trace alkaloid possessing the lignan structure, named oleraisoindole A, was obtained from the extract of the Portulaca oleracea L.. The structure of oleraisoindole A was elucidated by 1D and 2D NMR and high resolution electrospray ionization time-of-flight mass spectroscopic methods. The compound presented an anticholinesterase effect with the IC50 value of 60.4 μM.

Keywords: Portulaca oleracea L.; alkaloids; anticholinesterase effect.
