OBJECTIVE To study the chemical constituents and anti-inflammatory activity of Periplocae Cortex. METHODS The chemical components in Periplocae Cortex were extracted and isolated by MCI resin column, silica gel column and gel column, and the structure of the monomeric compounds was identified by nuclear magnetic resonance spectroscopy, mass spectrometry, infrared spectroscopy, etc. The Griess method was used to test the lipopolysaccharide-induced model of inflammatory factor release from mouse monocyte macrophage RAW264.7 cells, and the anti-inflammatory activity of the compound was evaluated. RESULTS A total of 6 compounds were isolated from Periplocae Cortex, including Δ5-pregnene-3β,20(S)-diol-3-O-[2-O-acetyl-β-D-digital-opyranosyl-(1→4)-β-D-cymaropyranoside]-20-O-[β-D-glucopyranosyl-(1→2)-β-D-digita-lopyranoside] (1), Δ5-pregnene-3β,17α,20α-triol (2), periplocoside L (3), periplocoside N (4), periplocogenin (5), periplocoside M (6). Compound 1 is a new compound, named periplocoside G1. In vitro anti-inflammatory activity studies showed that 1, 5, and 6 showed antiinflammatory activities. CONCLUSION The isolated and identified compounds and their activities provide a basis for the rational development and utilization of medicinal resources.
