RESUMO
Objective To study the chemical constituents of the fruits of Garcinia multiflora. Methods The constituents were isolated and purified by silica gel column chromatography and semipreparative HPLC, and their structures were elucidated by means of spectroscopic analyses. Results Six compounds were obtained and identified as multiflorone A (1), sargaol (2), δ-tocotrienol (3), luteolin (4), 1,3,6,7-tetrahydroxyxanthone (5), terephthalic acid bis (2-ethyl-hexyl) ester (6). Conclusion Compound 1 is a new homoadamantyl type phloroglucinol, and compounds 2, 3 and 6 are isolated from this plant for the first time.
RESUMO
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.
