Abstract:
Objective: To study the chemical constituents from the root barks of Cudrania cochinchinensis. Methods: The chemical constituents were isolated and purified by silica gel column chromatography. The structures of the compounds were identified on the basis of spectral data (MS, 1H-NMR, 13C-NMR, and 2D NMR) and by the comparison of spectroscopic data with the reported values in the literatures. Results: A new xanthone, 1,6,7-trihydroxy-4-(1,1-dimethylallyl)-3-methoxyxanthone (1) and a known prenylated xanthone 1,5,6-trihydroxy-4-(1,1-dimethylallyl)-3-methoxyxanthone (isocudraniaxanthone B, 2) were isolated from the root barks of C. cochinchinensis. Conclusion: Compound 1 is a new prenylated xanthone. Isomers 1 and 2 are obtained from this plant for the first time. © 2013 Tianjin Press of Chinese Herbal Medicines.
