Two new spirostane glycosides, named polygokingiaside A (1) and polygokingiaside B (2), and 6 known spirostane glycosides, (25R)-26-O-(β-d-glucopyranosyl)-furost-5-en-3β,22α,26-triol 3-O-β-d-glucopyranosyl-(1→4)-β-d-galactopyranoside (3), (25S)-26-O-(β-d-glucopyranosyl)-furost-5-en-3β,22α,26-triol 3-O-β-d-glucopyranosyl-(1→2)-β-d-glucopyranosyl-(1→4)-β-d-galactopyranoside (4), (25R)-26-O-(β-d-glucopyranosyl)-furost-5-en-3β,22α,26-triol 3-O-β-d-glucopyranosyl-(1→2)-β-d-glucopyranosyl-(1→4)-β-d-galactopyranoside (5), (23S,25R)-spirostan-5-en-3β,23-dihydroxy-12-one-3-O-β-d-glucopyranosyl-(1→2)-β-d-glucopyranosyl-(1→4)-β-d-galactopyranoside (6), (24S,25R)-spirostan-5-en-3β,24-dihydroxy-12-one-3-O-β-d-glucopyranosyl-(1→2)-β-d-glucopyranosyl-(1→4)-β-d-galactopyranoside (7), and (25R)-spirostan-5-en-3β-hydroxy-12-one-3-O-β-d-glucopyranosyl-(1→4)-β-d-galactopyranoside (8), were isolated from the roots of Polygonatum kingianum Collett & Hemsl. (Asparagaceae). Their structures were determined by extensive analysis of high-resolution electron spray ionization mass spectrometry and nuclear magnetic resonance spectral data, as well as by comparison of the spectral data with those reported in the literature. Anti-inflammatory activity of compounds 1-8 was evaluated by their inhibition of nitric oxide (NO) production in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. At a concentration of 20 µM, compounds 1-8 exhibited a modest inhibitory effect on NO production in LPS-stimulated RAW246.7 cells with inhibitory values ranging from 9.5 ± 0.8% to 33.8 ± 2.1%.
