Phytochemicals from Calophyllum depressinervosum

A phytochemical investigation on the stem bark of Calophyllum depressinervosum resulted in the isolation of four xanthones, one coumarin and one kavalactone which were elucidated to be caloxanthone B (1), caloxanthone I (2), caloxanthone J (3), xanthochymone B (4), calopolynolide B (5) and desmethox...
