Abstract

Background & Aim: Free radicals play a crucial role in the development of tissue damage in various human diseases such as cancer, aging, neurodegenerative disease, malaria and arteriosclerosis, and pathological events in living organisms. Antioxidants may have an important role in the prevention of these diseases. The aim of this study is to evaluate potency of scavenging of DPPH free radicals in the circulatory system of rats by the methanolic extracts of Salvia aethiopis. This species belongs to the genus Salvia of the family Lamiaceae, many species of which are valuable in food and medicine. Further studies will indicate whether this plant can be as a suitable candidate for pharmacological and industrial applications. Experimental: Ten female rats (200-250 g) were randomly selected and then divided in three groups. The rats were injected intraperitoneally with 0.5 ml of 1, 1-diphenyl-2-picryl hydrazyl (DPPH) free radical in methanol (3×10-4 M), 1 ml of methanolic extract of S. aethiopis (1 mg/ml) along with 0.5 ml of methanolic solution of DPPH and 1 ml of ascorbic acid along with 0.5 ml of methanolic solution of DPPH as positive control, respectively. The absorbance of DPPH solution in the blood serum of rats was measured by spectrophotometric method in 517 nm. Results & discussion: Decrease in absorbance of DPPH free radical (1.85 nm) in circulatory system of the rats in presence of ascorbic acid as positive control (1.07 nm) and S. aethiopis extract (0.78 nm) as sample. It can be concluded that the potency of free radical scavenging by the metabolic extract of S. aethiopis in circulatory system of the rats is more than that of ascorbic acid. Industrial and practical recommendations: The Results from present investigation showed that S. aethiopis extract can be used as a natural compound with a high antioxidant activity in future studies.

Abstract

Background & Aim: Aphids are of serious pests and vectors of multitude of viral diseases of field crops, vegetables, ‎and greenhouse crops. They have displayed a remarkable ability to establish resistance to ‎almost every insecticide with which it has been treated. To reduce the damage of these pests ‎and dependence on the sometimes unwise use of synthetic pesticides in crop and vegetable ‎plantations, the toxicity of ethanolic seed extract of Melia azedarach L. (Meliaceae) was ‎assayed against 3-4 days-old individuals of Aphis gossypii Glover and Myzus persicae (Sulzer) ‎‎(Hemiptera: Aphididae).‎ Experimental: In this study, M. azedarach L. seeds were collected from Kerman, Iran. They were milled and ‎powdered and extracted with ethanol (95%) solvent. All experiments with different ‎concentrations were conducted by topical test bioassay in laboratory. The treated aphids were ‎reared at 25±1 °C temperature, relative humidity of 60±10 % and 16 hours of artificial light at ‎an intensity of about 4000 lux. Ethanol (95%) was used as control treatments. ‎ Results & Discussion: The results indicated that in the concentration 60 µl/ml, the mortality of A. gossypii treatment ‎after 24 h was 95% and it was significantly higher than M. persicae treatment (p<0.005). ‎Also the LC50 of ethanol seed extracts of M. azedarach for A. gossypii and M. persicae after ‎‎24 hr was 13.7 and 15.0 µl/ml, respectively.‏‎ It is concluded that the ethanolic seed extract ‎of M. azedarach may be applicable as a safe insecticide to aphid's control in IPM programs‏.‏

Abstract

Background & Aim: Because of seed germination ability of medicinal plants seed is low and, generally exposed to problem. Priming is one of the techniques that help seeds to be germinated faster and uniformly. Experimental: A laboratory experiment was carried out on germination and growth improvement in Heracleum persicum Desf. by seed osmo-primming in Seed Technology Laboratory of Faculty of Agriculture in Birjand University, Iran. Statistical design was factorial RCBD with three replications. Factors were priming media (Polyethylen glycol 6000 (PEG), KNO3 and CaCl2), osmotic potential of solution (-0.5, -1 and -1.5 MPa) and time of treatment (12 and 24 h). Results & Discussion: The results showed that priming media had significant effect on all of evaluated characteristics. Germination rate significantly was affected by osmotic potential of solutions. Time of treatment was also effective on germination rate and MGT. However, CaCl2 in 24h and -0.5 MPa, PEG in 24h and -1 MPa, PEG in 12h and -1.5 MPa and KNO3 in 24h and -1 Mpa were best treatments in germination percentage and rate, seedling vigor index and MGT respectively. Therefore, suitable priming treatments are able to improve germination traits in Heracleum persicum. Industrial and Practical Recommendations: The findings showed that priming leads to increasing the traits of blossoming in hogweed. Since cumarin is used in various industries and its seed is week in blossoming, using priming can be helpful for blossoming and fixating of this plant and can be increase the production.

Abstract

Background & Aim: The plants of the greenhouse have been affected by infestation of the pest Trialeurodes vaporariorum, called greenhouse whitefly, which markedly reduced production. Synthetic insecticides have been widely developed and, their extensive use has brought about disadvantages, like environmental disturbance, pest resistance, lethal effects on non target organisms and toxicity to users and consumers. One alternative for control this invasive pest is the use of natural insecticides, active component isolated from the plants. Green insecticides tend to have broad spectrum activity relatively specific in their mode of action and easy to process and use. The effects of methanolic extracts of Melia azedarach L. and Peganum harmala L. on nymphal and pupal developmental duration of T. vaporariorum investigated under laboratory condition. Experimental: In both of the experiments, the leaf discs of bean plants with new hatched nymphs or pupae were placed into the round plastic petri-dishes (5 cm diameter) that filled with agar gel. The individuals of the nymph and pupa instars were treated with the concentration of M. azedarach and P. harmala extracts (80 mg/ml). In control group, water distilled was applied. Results & Discussion: The results indicate that the both methannolic extracts significantly increased nymphal developmental duration as compared to control. While, there was no significantly difference on pupal developmental duration in different treatments. The effect of plant extracts on nymphal developmental duration could be controlled on population dynamic of T. vaporariorum. Also, they could be delayed immature stages of greenhouse whitefly. Moreover, botanical pesticides appear to have potential as a good organic insecticide and provide for pest control an alternative to currently used pesticides.
