“…recutita, C. verbenacea, T. vulgaris, C. citratus and C. martini at 0.1% corroborates similar studies carried out in several other pathosystems. In these, inhibition of germination or mycelial growth caused by pure essential oils, or by one or more of their constituents identified as major in this study (Table 3), could be noted on applying different concentrations and in various forms (WILSON et al, 1997;KASALI et al, 2001;SAIKIA et al, 2001;PARANAGAMA et al, 2003;KISHORE et al, 2007;DE OLIVEIRA et al, 2010;BASSOLÉ et al, 2011;KHAN;AHMAD, 2011). Control of P. griseola using essential oils, however, is reported here for the first time.…”

Pseudocercospora griseola, the etiologic agent of angular leaf spot of common bean (Phaseolus vulgaris), is an important disease in all bean-producing regions worldwide and may cause extremely high yield losses. The control of this disease is made more difficult by the pathogen's genetic variability and the inefficiency of fungicides. In this study, of 26 essential oils tested at different concentrations, 25 demonstrated efficiency in affecting the germination of strains 63-31 and 63-63 of the pathogen, reaching inhibition levels of between 80% and 100%. Cymbopogon citratus and Cymbopogon martinii inhibited conidia germination at all concentrations; Eugenia caryophyllata, Cinnamomum sp., Thymus vulgaris, Matricaria recutita, Cordia verbenacea, Origanum vulgare, Cymbopogon nardus, at 0.1 and 0.5%; and Zingiber officinale, Mentha arvensis, Chamaecyparis pisifera, Lavandula officinalis, Ocimum basilicum, Pimpinella anisum, Ocimum selloi, Baccharis dracunculifolia, Laurus nobilis, Citrus sinensis, Melaleuca alternifolia and Eucalyptus globulus, at 0.5%. The main constituents identified were cinnamaldehyde in Cinnamomum sp.; eugenol in E. caryophyllata; trans-β-farnesene in M. recutita; pulegone in C. verbenacea; thymol in T. vulgaris; geranial and neral in C. citratus, and geraniol in C. martini. Through transmission electron microscopy (TEM), it was verified that C. citratus, C. martini and E. caryophyllata presented direct fungitoxic action on P. griseola, causing severe damage to the cellular ultrastructure of the conidia, invalidating germination. These results indicated that essential oils are a promising alternative strategy for the control of angular leaf spot in bean, representing less risk to human health and the environment.

“…Analysis of C. citratus species from Brazil [42], India [43], West and Eastern Africa [43][44][45][46][47][48][49] and Asia [50] showed the high value of neral and geranial chemotypes. A special distinguishing feature between C. citratus of African origin is the high amount of myrcene observed in them [44][45][46][47][48][49]. High occurance of piperitone (27) characterizes the oils of C. parkeri and C. olivieri from Iran.…”

Abstract:Cymbopogon genus is a member of the family of Gramineae which are herbs known worldwide for their high essential oil content. They are widely distributed across all continents where they are used for various purposes. The commercial and medicinal uses of the various species of Cymbopogon are well documented. Ethnopharmacology evidence shows that they possess a wide array of properties that justifies their use for pest control, in cosmetics and as anti-inflammation agents. These plants may also hold promise as potent anti-tumor and chemopreventive drugs. The chemo-types from this genus have been used as biomarkers for their identification and classification. Pharmacological applications of Cymbopogon citratus are well exploited, though studies show that other species may also useful pharmaceutically. Hence this literature review intends to discuss these species and explore their potential economic importance.

“…Also the oil has the tendency to polymerise because of high content (5-25 %) of the monoterpene β-myrcene in the oil, thus deteriorating the quality of the oil 1 . This oil has been the subject of several studies by many researchers from different countries [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] . According to a recent review a total of 158 compounds were identified in this oil by several research groups from different countries 2 .…”

Essential oils of Cymbopogon citratus (DC.) Stapf grown in three different locations in South India were analysed by GC and GC-MS. The main constituents of the oils from Bangalore and Puttur were identified as β-myrcene, neral, geranial and geraniol. The oil from Nadugani was found to contain the major constituents' neral, geranial, geraniol and geranyl acetate. The present study revealed the presence of six oxygenated monoterpenes and sesquiterpenes which were hitherto not reported in the oil of C. citratus.
