Aralianudaside A, a triterpene saponin with an unusual skeleton of pentacyclic triterpenoid, along with a new triterpene glycoside and six known compounds were obtained from the buds of Aralia elata. Their structures were determined through extensive spectral analysis, including HRESIMS, IR, 1D and 2D NMR, glycolysis and GC. All compounds were evaluated for anti-airway inflammatory activity in lipopolysaccharides (LPS)-induced airway epithelial cells (16HBE), compounds 1, 3, 5, 7 and 8 significantly decreased the expression of pro-inflammatory cytokines IL-1β and IL-4.
