Twelve medicinal plants and a commercially used drug Ivermectin were examined for insecticidal activity against Melophagus ovinus sheep ked at different time intervals using in vitro adult immersion test. The findings show that at 3.13 µL/mL, 6.25 µL/mL and 12.5 µL/mL concentration of Cymbopogon citratus, Foeniculum vulgare and Eucalyptus globulus essential oils respectively, recorded 100% mort...

Cymbopogon citratus has been shown to have antioxidant, antimicrobial, antispasmodic and chemo-protective properties. Citral, is the major constituent of C. citratus. This study investigated the effects of methanolic extracts of leaves (LE), stems (SE), and roots (RE) of C. citratus and citral on vascular smooth muscle and explored their possible mechanisms of action. The experiment was conduct...

The biomass production of Cymbopogon citratus shoots cultivated in bioreactors according to the temporary immersion (TIS) principle was assessed under different growth conditions. The effect of gassing with CO2-enriched air, reduced immersion frequency, vessel size and culture time on total phenolic and flavonoid content and free radical scavenging effect of the methanolic extracts was measured...

The study aims at synthesizing silver nanoparticles using leaf extract of Cymbopogon citratus along with the evaluation of its antioxidant, free radicals scavenging, and reducing power properties. Biosynthesized silver nanoparticles were characterized X-Ray diffractometry, Scanning Electron Microscopy, Transmission Electron Microscopy, Fourier Transform Infrared spectroscopy and Energy Dispersi...

The use of antibiotics in agriculture is limited when compared to their applications in human and veterinary medicine. On the other hand, the use of antimicrobials in agriculture contributes to the drug resistance of human pathogens and has stimulated the search for new antibiotics from natural products. Essential oils have been shown to exert several biological activities including antibacteri...

Eleven essential oils, namely, Cananga odorata (Annonaceae), Cupressus sempervirens (Cupressaceae), Curcuma longa (Zingiberaceae), Cymbopogon citratus (Poaceae), Eucalyptus globulus (Myrtaceae), Pinus radiata (Pinaceae), Piper crassinervium (Piperaceae), Psidium guayava (Myrtaceae), Rosmarinus officinalis (Lamiaceae), Thymus x citriodorus (Lamiaceae) and Zingiber officinale (Zingiberaceae), wer...

Cymbopogon citratus is a medicinal plant popularly used in Brazil for the treatment of various diseases, and the research interest in this plant is justifiable because of its potential medicinal value in stomachache and gastric ulcer. This study was aimed to test the validity of this practice by using experimental models of gastric ulcer and to clarify the mechanisms of gastroprotection by C. c...

Several Cymbopogon species such as C. citratus, C. flexuosus, C. nardus and C. khasianus×C. pendulus are extensively used for flavors, fragrance and as folk medicines worldwide due to their volatile essential oils (VEOs). Direct analysis in real time mass spectrometry (DART-MS) method was developed for identification of VEOs from the intact plant parts of ten Cymbopogon species. Total sixteen c...

The aim of this study is to develop a microemulsion product from a plant essential oil having the highest anti-tyrosinase activity. The in vitro anti-tyrosinase activity of six essential oils extracted from six edible plants was compared. The oil of Cymbopogon citratus demonstrated the highest activity which was significantly nontoxic to normal human cells. The GC-MS data indicated that gerania...

The effectiveness of aqueous extract of seven locally available medicinal plants i.e. Trachyspermum ammi (seeds), Zingiber officinale (rhizome), Tinospora cordifolia (leaves), Cymbopogon citratus (leaves), Moringa oleifera (bark) were evaluated against the plant pathogenic fungus i.e. Fusarium oxysporum f. sp. lini (causing wilt in linseed). The plant extracts were screened for their antagonist...
