Three New Glycosides From the Stems of Derris elliptica.

Three new glycosides, derriacuminosides A-C (1-3), were isolated from the stems of Derris elliptica (Wall.) Benth. Their chemical structures were determined by interpretations of HRESIMS and NMR spectra. The anti-inflammatory activity of compounds 1 - 3 were evaluated by inhibiting NO production in LPS activated RAW264.7 cells. Compounds 1-3 potentially inhibited NO production with IC₅₀ values of 26.54 ± 3.08, 26.35 ± 1.37, and 49.71 ± 2.93 µM, respectively, compared to the positive control, L-NMMA (IC₅₀ 35.56 ± 2.98 µM).
