Objective:
To study the chemical constituents of the barks of Garcinia tetralata.
Method:
Compounds were isolated and purified repeatedly by silica gel and ODS column chromatography and their chemical structures were elucidated by their physicochemical properties and spectral data analysis.
Result:
Ten compounds were obtained and identified as 1, 7-dihydroxyxanthone (1), buchanaxanthone (2), garciniaxanthone H (3), 1, 2, 5-trihydroxyxanthone (4), subelliptenone H (5), 6-desoxyjacareubin (6), 6-deoxyisojacreubin (7), subelliptenone G (8), methyl orsellinate (9) and beta-sitosterol (10).
Conclusion:
Compounds 1-10 were isolated from this plant and compound 9 was obtained from the genus Garcinia for the first time.
