Chemical investigation of Garcinia eugenifolia and Calophyllum enervosum yielded six compounds. One of these was found to be a novel compound identified as enervosanone. Five known compounds cambogin, epicatechin, osajaxanthone, rubraxanthone and isocowanol, were also isolated. These compounds were tested for their bioactivity as antimicrobial, antioxidant and cytotoxicagents. Antimicrobial...

The antioxidant and antimicrobial activity of methanol or dichloromethane extracts of O. dictamnus, produced from wild and organic cultivated specimens, were determined. The Rancimat and malondialdehyde (MDA) by HPLC methods were used to measure the antioxidant action, in comparison with that of the common commercial antioxidants butylated hydroxytoluene (BHT) and alpha-tocopherol. The extracts...
