The chemical composition of the essential oil obtained from the aerial parts of Cleome serrata by hydrodistillation was analyzed by employing GC-FID, GC-MS and RI. Fourteen compounds comprising 90.4% of the total oil composition were characterized. The main components identified were ( Z)-phytol (53.0%) and di(2-ethylhexyl)-phthalate (DEHP) (14.7%). The oil was evaluated for its in vitro antimicrobial activities against nine pathogenic microorganisms using the filter paper disc diffusion method. Moderate antimicrobial activity was observed against five of the pathogens assayed. In addition, the essential oil was tested against the sweet potato weevil, Cylas formicarius elegantulus. Strong knockdown insecticidal activity was observed.

The aerial parts of Tetrataenium nephrophyllum were collected at the flowering stage, hydrodistilled, and the essential oil was analyzed by GC and GC-MS. Forty components accounting for 97.9% of the total oil were identified. Germacrene D (38.5%), 2-ethylhexyl acetate (11.2%), n-octyl 2-methylbutanoate (9.2%) and geranyl isovalerate (8.3%) were the major constituents. Sesquiterpene hydrocarbons (51.3%) and aliphatic esters (40.4%) were found to be the main group of compounds. The antimicrobial activity of the essential oil of T. nephrophyllum was determined against seven Gram-positive and Gram-negative bacteria (Bacillus subtilis, Enterococcus faecalis, Staphylococcus aureus, S. epidermidis, Escherichia coli, Pseudomonas aeruginosa and Klebsiella pneumoniae), as well as three fungi (Candida albicans, Saccharomyces cerevisiae and Aspergillus niger). The bioassay showed that the oil exhibited moderate to high antimicrobial activity.
