Two 2,7'-cyclolignans, ocholignans A and B, were obtained as mass-limited samples from Scyphocephalium ochocoa via high-throughput natural products chemistry methods. The rapid structure elucidation of each compound was primarily facilitated by NMR data acquisition using a capillary-scale NMR probe, CapNMR probe. Ocholignan A was found to possess significant in vitro antibacterial activity against Gram-positive bacteria methicillin-resistant Staphylococcus aureus ATCC 33591 and S. aureus 78-13607A with a MIC of 16 microg/mL, respectively.

The phytochemical investigation of the dichloromethane/methanol (1:1) extract of the stem bark of , led to the isolation of one new dibenzofuran derivative, named scyphocephalione A (), along with three other compounds, including epicatechin (), gentisic acid () and myo-inositol (). The structures of all the compounds were established with help of spectroscopic data including IR, UV, MS, 1 D- and 2 D-NMR, as well as by comparison with previously reported data in literature, and chemical modification. All the compounds were obtained from the genus for the first time.
