Objective To study the chemical constituents in stems-leaves of Garcinia multiflora. Methods The chemical constituents from stems-leaves of G.multiflora were isolated by silica gel and HPLC methods. Their structures were elucidated by spectroscopic methods and physicochemical properties. Results One new depsidone isolated from stems-leaves of G.multiflora was named as multidepsidone A (1), and four xanthones isolated from stems-leaves of G.multiflora were identified as isojacareubin (2), jacareubin (3), isocudraniaxanthone B (4), and 2-dimethylallyl-1,3,5-trihydroxyxanthone (5). Conclusion Compound 1 is a new compound. compounds 2-4 are known compounds, and compounds 2 and 5 are obtained from this plant for the first time.
