The use of Eucalyptus trees, in association with other plants, has the potential to reduce the growth of neighbouring plants or grasses by competing for resources or releasing allelochemicals that may cause other plants to grow slowly. Our purpose here is to assess whether border planting of Eucalyptus is harmful to the establishment,growth, and production of cymbopogon winterianus at various distances from tree lines in the Wondo Genet Agricultural Research Center in Southern Ethiopia. Several factors were studied: growth performances and yield of aromatic grasses; soil properties, including total nitrogen,organic carbon, and moisture content; and plant leaf nutrient content(NPK) at various distances away from the Eucalyptus citriodora border line were studied. Chemical compositions of hydro-distilled essential oils obtained from selected C. winterianus grasses leaves were analysed by gas chromatography. Plant height, biomass yield, amount of essential oil yield, and essential oil composition all were significantly affected due to Eucalyptus effect in the first10-m distance as compared to beyond 10 m from the tree border line. There were increases in soil total nitrogen,organic carbon, and moisture content with decreasing distances to the Eucalyptus tree border. The result of plant leaf nutrient content(NPK) differed across treatment and distance. The pot experiment(15 cm 9 20 cm), shoot length,and number of leaves of aromatic plants varied in the degree of inhibition based on the concentration of the aqueous extract. Significantly higher inhibitions of the shoot length and number of leaf parameters were observed when using 25% fresh leaf extract compared to other extract levels.

Objective: To evaluate the essential oil composition and the anti-inflammatory activity of cymbopogon validus(C. validus) leaves and flowers. Methods: A total of 300 g of fresh or dry(leaves and flowers) of C. validus were cut into small pieces and subjected to hydro-distillation method for approximately 5 h using the Clevenger apparatus. The extracted essential oils were then used for testing the anti-inflammatory activity. The anti-inflammatory activity was evaluated by using egg-albumin induced paw edema. Results: The extracted oils had the following yields 2.2% for fresh leaves, 2.0% for dry leaves and 2.4% v/w for dry flowers. GCMS results revealed that the oils contained artemisia ketone(37.5%), linalool(3.2%-29.6%), northujane(4.4%-16.8%), verbenone(13.5%), naphthalene(1.7%-9.6%), δ-cadinene(0.5%-8.1%), hedycaryol(5.4%-7.6%) and α-eudesmol(6.5%-6.7%) as the major constituents. C. validus essential oils showed significant(P<0.05) anti-inflammatory effects from the first 30 min after albumin injection compared to aspirin which had a later onset of effect. Conclusions: The findings of this study show that the essential oil extracted from C. validus fresh or dry leaves and flowers have anti-inflammatory properties; that might be associated with the major components and the minor components found in the essential oils.

Diuretics are efficaciously used in management of various clinical emergencies like hypertension, heart failure, cirrhosis, hypercalciuria, hematuria and nephrotic syndrome. cymbopogon jwarancusa is an aromatic perennial grass used in both traditional and Unani system of medicine to eradicate diseases like colds, seasonal fever, asthma, tuberculosis, rheumatic pain, back pain, toothache and nervous disorders. C. jwarancusa essential oils are used in perfumery, soap, detergents, medicines and pharmaceutical industry. Monoterpenes and sesquiterpenes constitute the highest composition in essential oil of C. jwarancusa. The present was designed to compare the diuretic activity of C. jwarancusa after single and multi-doses. Furosemide (20 mg/kg) was used as reference drug and 10% DMSO was used as vehicle. Diuretic activity was noticed by measuring urine volume and calculating diuretic and Lipchitz values. Maximum diuretic response was observed at 500 mg/kg of extract after both single and multi-dose administration. On basis of results it may be concluded that C. jwarancusa may be used as diuretic agent.

Evaluation of Control Strategies for cymbopogon nardus in Grazing Areas of Uganda

引用

Journal of Agricultural Science and Technology(B) 2013年第9期3卷 656-660页

作者： Gilbert Steven Byenkya Gadi Gumisinza Howard Kasigwa National Agricultural Research Organization (NARO) Mbarara Zonal Agricultural Research and Development Institute Mbarara Uganda National Agricultural Research Organization (NARO) Entebbe Uganda

cymbopogon nardus is an invasive grass weed in the grazing lands of Uganda affecting growth of desirable species and impeding movement of livestock. Farmers have for long used manual removal with a hand hoe to control the weed to allow growth of palatable species. In order to reduce on the drudgery associated with the hand hoe, a trial was set up to evaluate removal with a hand hoe, use of fire and spraying the weed with glyphosate herbicide to control cymbopogon nardus. Eight treatments associated with the different control strategies were replicated on four sites in the land use system. Both manual removal with a hand hoe and spraying with glyphosate herbicide were effective in controlling cymbopogon nardus with 95% and 92% kill of cymbopogon tussocks, respectively. The differences between the two control methods were not significant. Plant species biodiversity recovery was faster in the manually controlled plots than in those sprayed with glyphosate, but the number of species was not significantly different. The frequency of occurrence of species was however significantly different with manually controlled plots registering a higher frequency of the species. Fire had no effect as a control strategy, but instead increased the number of tussocks, growth vigour of the re-growth, flowering and hence seed setting. After three seasons, no significant difference was observed in species biodiversity between manual and herbicide control. These results suggest that herbicides could effectively be used to control cymbopogon nardus to cut on costs and avoid the drudgery normally associated with manual control.

Chemical composition, antiproliferative, antioxidant and antibacterial activities of essential oils from aromatic plants growing in Sudan

引用

Asian Pacific Journal of Tropical Medicine 2016年第8期9卷 741-748页

作者： Sakina Yagi Randa Babiker Tzvetomira Tzanova Herve Schohn Department of Botany Faculty of Science University of Khartoum Department of Botany Faculty of Science University of Kordofan Universite de Lorraine-UMR CNRS 7565-Structure et Reactivite des Systemes Moleculaires Complexes-Campus Bridoux-rue du General Delestraint57070 Metz Cedex

Objective: To explore the potential of essential oil, as therapeutic molecule source, from olibanum of Boswellia papyrifera(Burseraceae), leafy stems of cymbopogon schoenanthus(Poaceae) and Croton zambesicus(Euphorbiaceae) and rhizome of Cyperus rotundus(Cyperaceae) found in Sudan. Respective essential oil was evaluated for antiproliferative, antibacterial and antioxidant activity. Methods: Essential oils were extracted by hydrodistillation and then analysed by gas chromatography coupled to mass spectrometry(GCMS). Anti-proliferative activity was determined against human cell lines(MCF7 and MDAMB231, HT29 and HCT116) by the thiazolyl blue tetrazolium bromide(MTT) procedure. Antioxidant activity was evaluated by diphenyl 2 pycril hydrazil(DPPH) assay. Antibacterial activity was determined against two Gram-positive and two Gram-negative bacteria by microdilution method. Results: The essential oil from olibanum of Boswellia papyriferacontained mainly alcohol and ester derivatives(46.82%) while monoterpenes(69.84%) dominated in Corton zambesicus oil. Sesquiterpenes were the most highly represented classes of terpene derivatives in Cyperus schoenanthus(71.59%) and Cyperus rotundus(44.26%). Oil of cymbopogon schoenanthus revealed the best anti-proliferative activity against HCT116 cell line with IC50 value at(19.1 ± 2.0) μg/m L. Oil of Croton zambesicus showed the best antioxidant activity [EC50(4.20 ± 0.19) mg/m L]. All oils showed good antibacterial activity against Escherichia coli, Bacillus subtilis and Staphylococcus aureus with minimum inhibitory concentration(MIC) value ranged from 16 to 250 μg/m L. Conclusions: The results suggest that the essential oils of these plants could be used as a source of natural anti-proliferative, antioxidant and antibacterial agents.
