b a ckground: application of plant derivatives have been suggested as alternative sources for mosquito control. m ethods: the root essential oil and methanol extract of c ionura erecta (l.) griseb was tested under laboratory conditions for larvicidal and skin repelleny activities against anopheles stephensi . the chemical compositions of essential oils were analyzed using gas chromatography- ma...

The seasonal variation of the chemical composition of the essential oil from fresh leaves of Tetradenia riparia (Hochst.) Codd grown in southern Brazil was analyzed by GC-MS, and the analgesic and antimicrobial activities of this oil were assayed. The yield of essential oil ranged from 0.17% to 0.26%, with the maximum amount in winter and the minimum in spring. The results obtained from princip...

BACKGROUND The essential oil from Mesosphaerum sidifolium (L'Hérit.) Harley & J.F.B.Pastore (syn. Hyptis umbrosa), Lamiaceae (EOM), and its major component, have been tested for toxicity and antitumor activity. METHODS EOM was obtained from aerial parts of M. sidifolium subjected to hydro distillation, and gas chromatography-mass spectrometry was used to characterize the EOM chemical composit...

Abstract Xylella fastidiosa is a plant-pathogenic bacterium that lives inside host xylem vessels, where it forms biofilm which believed to be responsible for disrupting the passage of water and nutrients. Pectobacterium carotovorum Gram-negative plant-specific causes not only soft rot in various plant hosts, but also blackleg potato by cell wall degradation. Chagas disease, caused Trypanosoma c...
