Abstract
Phytochemical study on the stem bark of Calophyllum andersonii has resulted in the isolation of five xanthones namely (1) caloxanthone I (2) pyranojacareubin (3) macluraxanthone (4) caloxanthone C and (5) euxanthone. In this study the compounds were subjected to various spectroscopic analyses including FT-IR GC-MS 1D and 2D NMR for structural elucidations. Furthermore these xanthones were obtained for the first time from Calophyllum andersonii a plant never reported before. All four extracts namely hexane chloroform ethyl acetate and methanol extracts of the plant showed moderate inhibitions against Bacillus subtilis.
