Venuloxanthone, a new pyranoxanthone from the stem bark of Calophyllum venulosum

A new pyranoxanthone, venuloxanthone (1), was isolated from the stem bark of Calophyllum venulosum, together with three other xanthones, tovopyrifolin C (2), ananixanthone (3) and caloxanthone I (4), along with two common triterpenes, friedelin (5) and lupeol (6). The structures of these compounds w...

The structures of these compounds were identified using several spectroscopic analyses which are NMR, GCMS and FTIR experiments.
