%X Four new lignan glycosides; urenalignosides A每D ( 1每 4), along with 12 known ones ( 5每 16) were isolated from Urena lobata. Their structures were determined on the basis of extensive spectroscopic and spectrometric data (1D and 2D NMR; IR; CD; and HRESIMS). Compounds 2每 4; 6; 7; 10; and 11 showed inhibition of nitric oxide production in lipopolysaccharide-induced RAW 264.7 macrophage cells with IC 50 values in the range of 25.5每98.4 米M (positive control; quercetin; IC 50 = 7.2 ㊣ 0.2 米M).
