Abstract During a chemotaxonomic survey of several Malaysian Calophyllum species, two new coumarins were isolatedfrom the bark of Calophyllumteysmannii var. inophylloide . Structure elucidation of the new coumarins, teysmanones A and B are presented and species varieties are discussed. The known calanone and inophyllums C and E were also isolated.
