N2 - Six compounds, 1-O-(2,3,4-trihydroxy-3-methyl)butyl-6-O-feruloyl-β-D- glucopyranoside, ethyl β-D-glucopyranosyl tuberonate, p-hydroxybenzoic acid, (-)-hydroxyjasmonic acid, caffeic acid, and 4-hydroxyacetophenone 4-O-[5-O- (3,5-dimethoxy-4-hydroxybenzoy])-β-D-apiofrunosy]]-(1→2)-β-D-glu- copyranoside, were isolated from the n-butanol-soluble fraction of sage leaf extracts. Their structures were determined by spectral methods (MS, NMR, and 2D-NMR), and their antioxidant activities were measured. Among them, two new glycosides were elucidated. All of these compounds showed DPPH free radical scavenging activity at the concentration of 30 mM, and caffeic acid was the most active compound.
