摘要：
Two new lignans, identified as 6,7-dihydroxy-4-(4 ''-hydroxy-3 ''-methoxyphenyl)-2-naphthoic acid, named Oleralignan C (1), and 4-(3,4-dihydroxyphenyl)-6-hydroxy-7-methoxy-2-naphthoic acid, named Oleralignan D (2), were obtained from Portulaca oleracea L. The structures were determined by spectroscopic methods, including UHPLC-ESI-QTOFMS, D-1 and D-2 NMR. Both Oleralignan C (1) and Oleralignan D (2) inhibited the inflammatory factors, IL-1 beta and TNF-alpha in RAW 264.7 cells induced by lipopolysaccharide (LPS). Both compounds also could clear 1,1-diphenyl-2-picryl-hydrazyl (DPPH) radicals indicating their antioxidant potential.
