Abstract:
Objective: To investigate the chemical compounds from the twigs of Morus multicaulis. Methods: The chemical constituents were isolated by various chromatographic methods from 90% ethanol aqueous extract of M. multicaulis and the structures were elucidated by a combined analysis of physicochemical properties, as well as spectroscopic methods including UV, IR, MS ECD and NMR. Results: Six flavonoids were isolated and the structures were identified as moritwigsone A (1), carpachromene (2), isobavachalcone (3), isoliquiritigenin (4), apigenin (5), and quercitrin (6). The absolute configuration of compound 1 was determined by electronic circular dichroism (ECD) calculation. Conclusion: Compound 1 is a new compound, named moritwigsone A, and compounds 2-4 are isolated from this plant for the first time.
