Phytochemical investigation of Arenga pinnata (Wurmb.) Merr. fruits led to the isolation of 5 new compounds, designated A. pinnata A-E (1–5), and 13 known compounds (6–18). All compounds were isolated from A. pinnata for the first time. Their chemical structures were identified based on extensive spectroscopic methods, including HR-ESI-MS, 1D and 2D-NMR. To the best of our knowledge, this is the first systematic scientific study on the chemical composition of the Arenga genus.
