Limited studies on C. cyphopetalum inspired us to investigate the chemical nature and therapeutic potential of the plant.Methods: Silica gel column chromatographic separation was used for isolation. 1D and 2D NMR spectroscopic analysis and literature data were used for structural elucidation. Agar well diffusion assay was used for evaluation of antibacterial activity against E. coli, P. aeruginosa, and S. aureus. DPPH assay was used to evaluate radical scavenging activities. Molecular docking was done by AutoDock Vina 4.2 open-source program. DFT calculations were performed using the Gaussian 16 program package.Results: Dichloromethane/methanol (1:1) roots extract afforded a new hydroxyl-spongiane diterpenoid lactone derivative, 3-hydroxyisoagatholactone ( 1), along with β-sitosterol ( 2) and ϵ-viniferin ( 3) whereas methanol extract afforded trans-resveratrol ( 4), gnetin H ( 5), tricuspidatol A ( 6), ϵ-viniferin-diol ( 7) and parthenostilbenin B ( 8). At 50 μg/mL, compound 3 recorded the highest inhibition against E. coli (8.55 ± 0.45
