Abstract

A xanthone derivative, artonin O(1),has successfully been isolated from root wood of Artocarpus rigida grown in Lampung, Indonesia. The structure of this compound has been carefully determined by some spectroscopy techniques and based on physical data. The antibacterial activity test on this compound towards Bacillus subtilis, showed that it has medium activity.
