摘要:
A methanolic extract of Alnus firma barks (Betulaceae) significantly attenuated nitric oxide production in lipopolysaccharide-stimulated BV2 microglia. Two new compounds, characterized as 4-hydroxy-2,6-dimethoxyphenyl 6'-O-syringoyl-beta-D-glucopyranoside (1) and 4-hydroxy-2,6-dimethoxyphenyl 6'-O-vanilloyl-beta-D-glucopyranoside (2), were isolated from the barks of A. firma using bioactivity-guided fractionation, together with two known phenolic glycosides (3, 4) and 11 known diarylheptanoids (5-15). Among these compounds, 1-4 and 6-11 showed significant inhibitory effect on lipopolysaccharide-induced nitric oxide production in BV2 microglial cells at concentrations ranging from 10 mu M to 100 mu M.
