Antibicrobial and cytotoxic compounds of Scorodocarpus borneensis (Olacaceae) and Glycosmis calcicola (Rutaceae)

The extracts of plants collected from the forest of Northern Malay Peninsula were tested against bacteria, fungi and CEM-SS leukemia cel1 line. Gram-positive Bacillus cereus and Gram-negative Pseudomonas aeruginosa which are commonly involved in skin infections, have been used for screening anti...
