Cymbopogon flexuosus, lemongrass, and C. martinii, palmarosa, are perennial grasses grown to produce essential oils for the fragrance industry. The objectives of this study were (1) to evaluate biomass and oil yields as a function of nitrogen and sulfur fertilization, and (2) to characterize their utility for lignocellulosic ethanol compared to Panicum virgatum (switchgrass). Mean biomass yield...

OBJECTIVE To examine the acaricidal effects of the essential oil of Cymbopogon citratus leaf extract (lemongrass) and ethanolic Azadirachta indica leaf extract (neem) against house dust mites Dermatophagoides farinae (D. farinae) and Dermatophagoides pteronyssinus (D. pteronyssinus). METHODS Twenty-five adults mites were placed onto treated filter paper that is soaked with plant extract and b...

Seventeen microbial species including 10 fungal taxa, two yeasts and five bacteria, were isolated from freshly prepared orange, guava and banana juices kept in open bottles at room temperature for 7 days. Eight different essential oils, from local herbs, were tested for their antimicrobial activity against these test organisms. The essential oils of Cymbopogon citratus, Ocimum basilicum and Ori...

The hexane and methanol extracts of the roots of Cymbopogon martinii var. motia have been investigated to afford mainly fatty acids and common sterols. A new hydroxy unsaturated fatty acid, namely, 16-hydroxypentacos-14(z)-enoic acid, has also been isolated.

In the current study, some plants were selected to screen their potential antibacterial activity. For evaluating activity, both aqueous and organic solvents) methanol acetone (were used. The tested Cymbopogon schoenanthus, Cotula cinerea, Francoeuria crispa. Agar well diffusion method was used test activity against two Gram negative (Brucella spp., Proteus spp.) three positive (Staphylococcus a...

The present study was designed to evaluate the anti-stress effects of ethanol extracts five medicinal plants from Southern part Tunisia, traditionally used in folk medicine: Cymbopogon schoenanthus Spreng. (CSEE), Crithmum maritimum L. (CMEE), Arthrophytum scoparium (Pomel) ll’jin (ASEE), Artemisia herba-alba Asso. (AHEE), and Rhanterium suaveolens Desf. (RSEE). Assays using SH-SY5Y cells HSP47...

Three carbonyl-containing extracts of essential oils from Eucalyptus citriodora (Myrtaceae), Cymbopogon citratus (Gramineae) and Lippia multiflora (Verbenaceae) were used for the preparation of oximes. The reaction mixtures were analyzed by GC-MS and different compounds were identified on the basis of their retention times and mass spectra. We observed quantitative conversion of aldehydes to th...

Antimicrobial activities of the leaf extracts of Cymbopogon citatrus (lemongrass) and Vernonia amygdalina (bitter leaf) and the seed extracts of Garcinia kola (bitter kola) were carried out. G. kola had effect only on Staphylococcus aureus and Escherichia coli with no inhibition on Candida albicans. Ethanol, cold water and hot water extracts of Vernonia amygdalina and Cymbopogon citratus showed...
