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...

Chemical composition and antimicrobial activity of exotic plants essential oils to potentially control Paenibacillus larvae, the causal agent of American foulbrood disease (AFB) were determined. AFB represents one of the main plagues that affect the colonies of honeybees Apis mellifera L. with high negative impact on beekeepers worldwide. Essential oils tested were niaouli (Melaleuca viridiflor...

In the present investigation the current status of medicinal plants used by traditional vaidyas is studied in Khandesh area of Maharashtra state, India. Information was gathered using semistructured questionnaires about various traditional vaidyas. They were questioned about the types of ailments treated with plants and the preparation of herbal medical formulation. The study of Cymbopogon citr...

Carbon dioxide compensation values of mature leaves from 10 selections of citronella (Cymbopogon nardus [L.] Rendle) grown at 32/27 or 27/21 C day/night temperatures and three strains of lemongrass (Cymbopogon citratus [D.C.] Stapf. and Cymbopogon flexuosus [D.C.] Stapf.) grown at 8- or 15-hour photoperiods were measured in a controlled environment at 25 C. All leaves had low compensation value...

Toxic heavy metals viz. lead, mercury and cadmium induced differential accumulation of proline in lemongrass (Cymbopogon flexuosus Stapf.) grown in soil amended with 50, 100, 200, 350 and 500 mg kg(-1) of the metals have been studied. Proline accumulation was found to be metal specific, organ specific and linear dose dependant. Further, proline accumulation following short term exposure (two mo...

background and objectives: this paper describes chemical composition and antimicrobial activity of cymbopogon nardus citronella essential oil against edwardsiella spp. (n = 21), vibrio spp. (n = 6), aeromonas spp. (n = 2), escherichia coli (n = 2), salmonella spp. (n = 2), flavobacterium spp. (n = 1), pseudomonas spp. (n = 1) and streptococcus spp. (n = 1) isolated from internal organs of aquat...

Ten selections of citronella (Cymbopogon nardus [L.] Rendle) were grown at 32/27, 27/21, or 15/10 C day/night temperatures, and plants from three populations of lemongrass (Cymbopogon citratus [D.C.] Stapf from Japan or Sri Lanka and Cymbopogon flexuosus [D.C.] Stapf from India) were grown at 8- or 15-hour photoperiods. Net photosynthetic rates of mature leaves were measured in a controlled env...

Carrageenan has been proved as potent growth promoting substance in its depolymerized form. However, relatively little is known about its role in counteracting the adverse effects of drought stress on plants. In a pot experiment, lemongrass (Cymbopogon flexuosus Steud.), grown under different water stress regimes [(100% field capacity (FC), 80% FC and 60% FC)], was sprayed with 40, 80 and 120 m...

We assessed the efficacy of 3% citronella candles and 5% citronella incense in protecting subjects from bites of Aedes spp. under field conditions. The study was conducted in a deciduous woodlot in Guelph, Ontario, Canada from July 26 to August 10, 1995. Eight subjects, dressed identically, were assigned to one of 8 positions on a grid within the study area. Two citronella candles, 2 citronella...
