The sugarcane smut disease caused by Sporisorium scitamineum occurs in all production areas. In order to contribute to the management of this disease, a study was carried out in vitro conditions. The aim of this study was to evaluate the antifungal efficacy and to determine the inhibitory concentration of the essentials oils of Ocimum gratissimum, Zingiber officinale and Cymbopogon citratus upon two strains B and Z of Sporisorium scitamineum. These oils were tested on mycelial growth of colonies, spores’ production and teliospores germination. The results showed a variable fungitoxic effect of the oils according to doses. Mycelial growth and spores production were totally inhibited (100%) from 1000 ppm by all the oils. The 90% inhibitory concentrations (IC90) obtained were 880.37 ppm, 847.83 ppm and 805.75 ppm for Ocimum gratissimum, Zingiber officinale and Cymbopogon citratus, respectively. The germination of teliospores was completely reduced by the three essential oils from 500 ppm upwards. Propiconazole had strong inhibitory effects at 400 ppm with a very low IC50 and the IC90 ranged from 305 ppm to 323.36 ppm. Moreover, at the level of the strains, no difference in resistance was observed These oils could provide a good means of controlling sugarcane smut.

The lemon grass, Cymbopogon citratus (DC) Stapf, is an important species of Poaceae family commonly used in the folk medicine in many countries. The aim of this study was to investigate the cytotoxic and genotoxic effects of aqueous extracts from C. citratus leaves on Lactuca sativa (lettuce) root tip meristem cells by cytogenetic studies that have never been done before for lemon grass extracts. For this, lettuce seeds were treated for 72h with different concentrations of lemon grass aqueous extracts (5; 10; 20 and 30 mg/mL). The percentage of germination, root development and cellular behavior were analyzed, and the results showed that the highest concentration of aqueous extracts reduced the mitotic index, the seed germination and the root development of lettuce. The extracts have also induced chromosome aberrations and cellular death in the roots cells of L. sativa.

Background: Depression is a common psychiatric disorder. Drug therapy is the cornerstone in the management of depression. Anti-depressants are associated with many unwanted side-effects. Thus, various herbal products have been tried. The advantages of herbal treatments include safety, cheap and acceptability due to their traditional values. The objective of the present study was to evaluate the anti-depressant activity of Cymbopogon citratus (lemon grass) in albino mice and to compare with Imipramine. Methods: 30 Swiss albino male mice weighing around 25-30 g were divided into 5 groups (n=6). Group I (Control) mice were given normal feed and water, Group II (Standard) received 20 mg/kg T. Imipramine orally, Group III (Test-1) received 5 mg/kg aqueous extract of C. citratus (lemon grass) orally and Group IV (Test-2) received 10 mg/kg C. citratus (lemon grass) orally, and Group V (Test-3) received both T. Imipramine (10 mg/kg) and C. citratus (10 mg/kg) orally. Duration of immobility was observed for last 4 mins of total 6 mins period in groups 1-5 by tail suspension test on 1st, 8th and 15th day.Results: Duration of immobility recorded in seconds was analyzed by one-way analysis of variance, followed by Tukey’s post-hoc test Conclusion: Lemon grass has a significant antidepressant effect. Combined effect of lemon grass at 10 mg/kg and imipramine 10 mg/kg is not synergistic.
