Abstract
Two new organic acids, identified as (7E,9E,12E)-pentadecyl-7,9,12-trienoic acid, named Oleraceacid A (1), and 6,7-dihydroxy-4-(4-hydroxy-3,5-dimethoxyphenyl)-2-naphthoic acid, named Oleraceacid B (2), were isolated from Portulaca oleracea L.. The structures were verified by spectroscopic methods, including UHPLC-ESI-QTOF/MS, 1 D and 2 D NMR. Both Oleraceacid A (1) and Oleraceacid B (2) at 20 μM inhibited the inflammatory factor, IL-1β in the RAW 264.7 cells induced by LPS, moreover, Oleraceacid A (1) can inhibit cholinesterase activity.
