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.

Significant Difference

Endophytic entomopathogenic fungi are being explored for the management of phytophagous insect pests. The effects of Beauveria bassiana (Hypocreales) inoculation of grape plants on the infestation level of P. ficus, tissue nutrient contents, and growth and volatile constituents of potted grape plants were assessed. Grapevine plants were individually inoculated with a suspension of 1 × 108 conidia mL−1 of B. bassiana by drenching before experimentally infesting each of them with thirty adult females of P. ficus. At four weeks post-treatment, the fungus was re-isolated from leaves of 50% of the fungus-exposed plants. However, no significant difference (p > 0.05) was observed in all the plant growth parameters measured in the fungus-treated and control plants. Plant tissue analysis revealed markedly higher contents of calcium (Ca) and magnesium (Mg) in the leaf tissue of plants exposed to the B. bassiana relative to the control. Gas chromatography mass spectrometry (GC-MS) analyses showed that a significantly (X2 = 5.1; p < 0.02) higher number of known anti-insect volatile compounds (nine) were present among fungus treated plants compared to the control plants (five). Naphthalene, which is toxic to insects and humans, was detected only in the volatiles of the fungus-exposed plants. B. bassiana did not have any significant effect on total polyphenol, alkaloid, and flavonoids. Overall, treatment with fungus did not inhibit the infestation by P. ficus. In conclusion, these findings shed light on some of the mechanisms involved in endophytic fungus-plant-insect interactions.
