Abstract: Vietnamese traditional medicine has utilised the roots of Polygala arillata Buch.-Ham. ex D. Don to treat acute arthritis, rheumatism, pain, and as a tonic ingredient. In this study, phytochemical analysis of the roots of P. arillata resulted in the isolation of one novel compound, named polygarinolide A (1), along with six known compounds (2–7). High-resolution electrospray ionisation mass spectrometry (HR-ESI-MS) and one- and two-dimensional nuclear magnetic resonance (NMR) spectroscopy were among the spectroscopic techniques used to identify their structures. Additionally, the absolute configuration of compound 1 was determined through ECD calculation. The NO inhibitory activity of purified substances was evaluated. Interestingly, compound 2 exhibited inhibitory activity on NO production in LPS-stimulated RAW264.7 cells (IC50 = 25.37 μM). Moreover, interactions and binding mechanisms of the most active chemical with cyclooxygenase-2 inhibitor (COX-2) and nitric oxide synthase (iNOS) proteins were investigated by molecular docking simulations. Our findings add to our understanding of the secondary metabolites generated by P. arillata and provide a sound scientific basis for future research into the plant’s potential anti-inflammatory properties.
