Four new triterpenoid bidesmosidic saponins (-) and a sesquiterpenoid glucoside (), together with nine known phenolic compounds (-), were isolated from the fruits of . Their structures were elucidated using 1D and 2D NMR spectroscopy and mass spectrometry data. The antioxidant capability of the isolated compounds was evaluated in human gingival fibroblasts. Compound decreased ROS production and promoted cell proliferation. It also counteracted the cell cycle blockade induced by a low concentration of HO decreasing the expression of p21 and CDKN2A (p16). Compound decreased the expression of inflammatory cytokines (IL-6 and IL-8) in response to inflammatory stimuli, supporting its possible use in periodontitis lesions.
