【 摘 要 】

The phytochemical investigation of Xylopia langsdorffiana led to the isolation of corytenchine, xylopinine, discretamine, xylopine, ent-atisan-16α-hydroxy-18-oic acid, 132 (S) hydroxy-173-ethoxyphaephorbide and quercetin-3-α-rhamnoside. Their structures were assigned based on spectroscopic analyses, including two-dimensional NMR techniques. Antioxidant activities of discretamine were measured using the 1,2-diphenyl- 2-picryl-hydrazyl (DPPH) free radical scavenging assay.
