The study was undertaken to determine antifungal potentials of some plant extracts against dry bubble (Verticillium fungicola) disease of white button mushroom (Agaricus bisporus). Twelve botanicals namely, Allium cepa, A. sativum, Saraca asoca, Aloe vera, Azadirachta indica, Lantana camara, Ocimum sanctum, Solanum lycopersicum (Lycopersicon esculentum), Tagetes erecta, Psidium guajava, Catharanthus roseus and Aparagus racemosus were evaluated in-vitro and in-vivo for their efficacy against both A. bisporus and V. fungicola, causing dry bubble disease of mushroom. The efficacy of botanicals was examined by poison food technique in in-vitro. The percent inhibition produced by botanicals against V. Fungicola recorded in-vitro was; A. cepa (25.87%), A. sativum (24.70%), S. asoca (12.35%), A. vera (22.35%), A. indica (35.11%), L. camara (28.48%), O. sanctum (20.59%), S. lycopersicum (20.34%), T. erecta (14.11%), P. guajava (15.11%), C. roseus (18.11%) and A. racemosus (13.52%). Among these plant extracts, A. indica was found best treatment followed by L. Camara and A. Cepa. Plant extracts showing maximum efficacy against V. fungicola and minimum inhibition against mushroom were further evaluated against V. fungicola infection in mushroom crop room (in-vivo test). In in-vivo test, the polybags which receive A. indica show maximum mean increase in yield (43.46%) over control and exhibited minimum mean disease incidence (27.7%).

Introduction: Diabetes mellitus is an endocrine and metabolic disorder characterized by the defect in insulin secretion or insulin action or both. The association between diabetes mellitus and oxidative stress is well established. Cucurbitaceae is the largest family containing 120 genera mostly grown for its sweet and juicy fruit in warm climates all over the world. In the present work ethanolic extracts of the seeds of Trichosanthes cucumerina Linn (Chichinno), Lagenaria siceraria (Lauka), Cucurbita pepo (Pharsi), Luffa aegiptiaca (Ghiraula), and Benincasa hispida (Kubindo) collected from Western Nepal has been evaluated for their in vitro antioxidant activity and in vivo hypoglycemic effects. Methods: In vitro antioxidant activity was assessed by using DPPH free radical scavenging activities and their IC50 values were calculated. In vivo hypoglycemic effect was examined on normoglycemic rats. The clinical significance of ethanolic extract at the doses of 250 and 500 mg/kg body weight was investigated in 0, 30, 60, 120 and 180 minutes of oral administration. Metformin treated group was used as the positive control. Results: For DPPH radical scavenging action, the IC50 values of Trichosanthes cucumerina, Luffa aegiptiaca, Benincasa  hispida, Cucurbita pepo, Lagenaria siceraria were found to be 60.72, 127.73, 49.63, 98.16 and 52.46 µg/ml respectively which were compared to the IC50 value of ascorbic acid (Positive control) which was found to be 38.11 µg/ml. The extracts of Benincasa hispida, and were having higher antioxidant activity and tested for in vivo hypoglycemic activity.In vivo administration of two doses of ethanolic extract of Lagenaria siceraria reduced the level of blood glucose while the best result was obtained at 250 mg/kg. Conclusions: Present study revealed promising antioxidant and hypoglycemic activity of ethanolic extract of Lagenaria siceraria. The further exploration of Lagenaria siceraria for its effective use in the traditional medicinal system is essential.

  The role of polyphenols and flavonoids in prevention of cellular damages carried out with the oxidative stress is well documented. In the present experiment, we determined the polyphenols and flavonoids concentrations of three extracts (ethanol 70%: V/V, methanol 80%: V/V and distilled water extracts) of carob pulp mature (Ceratonia siliqua L.) and their in vitro and in vivo antioxidant activity. A significant dose-dependent anti-free radical activ-ity of ethanolic extract of carob (EEC) was related to the highest polyphenol content (44.74 mg QE/mL) and to the in vitro antioxidant activity (EC50 = 0.28 mg/mL) of this extract. LC-MS /MS analysis of the EEC have shown the presence of several phenolic compounds as well as many types of flavonoids. The in vivo experiment brought out the significant effect of the daily EEC oral pre-treatment of rats, 30 min before AlCl3 administration for 28 d on the improvement of the total blood antioxidant capacity. These results suggest that the carob pulp contain many substances having in vitro and in vivo antioxidant effects, and which could be used as natural food additives in order to preserve food quality.

Background : Nowadays with the appearance of diseases such as cancer, atherosclerosis, free radicals are often singled out. What motivates scientific research in natural antioxidants. Aim/Objective : The aim of this study was to determine the antioxidant activity of the stalks and the fruit of Solanum melongena L. Study Duration : The period of the study was done on 25th July, 2015 at the Department of Pharmacy, Faculty of Medecine, Pharmacy and Odontology, University of Dakar, Senegal. Methodology : Antioxidant activity was evaluated through two methods (DPPH and FRAP). Results : For the FRAP test, at the highest concentration (83.3 µg/ml) the aqueous extract of the fruit (0.90±0.08) has a higher reducing power compared to those of ethanol extracts from the fruit (0.77±0.41) and the stalk (0.85±0.004). These results remain inferior to that of tannic acid (0.95± 0.0005). The DPPH test reveals that the ethanolic extract of the fruit is more effective in reducing the free radical DPPH with an inhibitory concentration 50 (IC 50) equal to 3.37±0.03 μg / ml, followed by the ethanolic extract of the stalks (IC 50 = 4.46±0.24 μg / ml) and finally the aqueous extract of the fruit (IC50 = 9.6±0.026 μg / ml). Conclusion : These results make it possible to confirm the in vitro activity of the parts studied, but in vivo studies are necessary in order to know the acute and chronic toxicities. Finally, perform a bio-guided fractionation to determine the molecules responsible for the antioxidant activity.

Objective: The present investigation focuses on the use of Cardiospermum halicacabum L. in their phytochemical and biological activities. Methods: In this study, in vivo stem and in vitro callus ethanolic extracts of C. halicacabum were tested for their phytochemical attributes by qualitative method, Fourier transform infrared (FTIR), antioxidant, antibacterial, and bioactive compound properties. The bactericidal activity of the in vivo stem and in vitro callus extract has been evaluated in both Gram+ve and Gram-ve microorganisms using the disk diffusion method. Results: The highest frequency (78%) of well developed, dark green organogenic callus was induced from stem explant on Murashige and Skoog (MS) medium supplemented with 0.7 mg/l 2,4-Dichlorophenoxyacetic acid (2, 4-D) and 0.5 mg/l benzyl adenine (BA). The results of FTIR spectra confirmed the presence of functional groups in wild stem and in vitro callus extract of C. halicacabum with various peaks. The total phenolic content in ethanolic extract of in vivo plant and in vitro callus was 80.46 mg gallic acid equivalent (GAE)/g dry weight and 76.4 mg GAE/g dry weight, respectively. The highest percentage of tannins was measured at 78.03 in wild stem ethanol extracts followed by 75.22 in callus extract. The antioxidant activity of 2,2-diphenyl-2- picrylhydrazyl (DPPH) ethanol extract was found to be 206.54 μg/ml. IC50 values of the stem extracts of C. halicacabum are 306 μg/ml and 286 μg/ml in callus extract, respectively. Antibacterial activity of the ethanol extract was higher for Staphylococcus aureus (S. aureus) with a 17 mm zone of inhibition. Conclusion: The present investigation recommended that the callus ethanolic extract function as a good source of biologically active compounds and natural antioxidants.

The isolates of two mycopathogenic fungi Verticillium fungicola and Mycogone perniciosa, and a commercial isolate of white button mushroom Agaricus bisporus were tested for sensitivity to prochloraz, benomyl, and iprodione in vitro. The pathogens were isolated from the diseased mushrooms originating from mushroom farms in Vracevsnica (Gornji Milanovac) and Pozarevac in Serbia. Prochloraz and iprodione were highly toxic to both M. perniciosa and V. fungicola. The isolate of M. perniciosa was also very sensitive to benomyl, whereas the toxicity of benomyl to V.fungicola was extremely low. Among the fungicides investigated, iprodion was the most toxic and benomyl the least toxic to the isolate of white button mushroom. Chemical control of both dry and wet bubble is possible by prochloraz and iprodione. Moreover, successful control of wet bubble causal agent can be obtained by benomyl as well, due to high toxicity of this fungicide to the pathogen and low toxicity to white button mushroom. In addition, use of benomyl alternating prochloraz provides resistance management strategy providing that a given farm is free of V.fungicola population.
