Three new iridoid glycosides were isolated from Lamiophlomis rotata using silica gel, gel Sephadex LH-20 column chromatography, and preparative high-performance liquid chromatography. The structures of the new compounds were elucidated through analysis of spectroscopic evidence, including data obtained from high-resolution electrospray ionization mass spectrometry (HRESIMS) and nuclear magnetic resonance (NMR). The absolute configurations of the three compounds were confirmed by a combination of sugar hydrolysis, derivatization, and electronic circular dichroism (ECD) calculations. The anti-inflammatory activities of methyl (1S,4aS,7aS)-7-methylene-1-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)-tetrahydro-2H-pyran-2-yl)oxy)-1,4a,7,7a-tetrahydrocyclopenta[c]pyran-4-carboxylate (1), methyl (1S,4aR,5R,7aR)-4a,5-dihy-droxy-7-methylene-1-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)-tetrahydro-2H-pyran-2-yl)oxy)-1,4a,5,6,7,7a-hexahydrocyclopenta[c]pyran-4-carboxylate (2), and methyl (1S,4aS,5R,7aS)-5-ethoxy-7-methyl-1-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)-1,4a,5,7a-tetrahydrocyclopenta[c]pyran-4-carboxylate (3) were evaluated by measuring nitric oxide (NO) production in LPS-stimulated RAW 264.7 macrophages. All these new findings showed significantly inhibited LPS-induced NO production at the concentration of 7.5 μmol/L.
