The aim of this work is to investigate the effects of film thickness, light intensity and Ag incorporation on the photoctalytic efficacy of zinc oxide films. ZnO films with different thicknesses were prepared using an automated home-made jet nebuliser spray technique. The results show that the thickness of the film has no appreciable influence on the photocatalytic efficiency of ZnO films whereas the light intensity strongly influences the photocatalytic activity of ZnO films. It is also found that doping of Ag with ZnO causes considerable enhancement in the photocatalytic activity. The dye degradation rate constant in the case of undoped ZnO film with thickness 400 nm is 0.0263min-1, whereas for Ag doped ZnO film having the same thickness, it is 0.0530 min−1. The reason for this enhancement in the photocatalytic efficacy of ZnO:Ag film is addressed with the help of optical band gap and the reported characteristics of Ag. © 2017 Institute of Materials, Minerals and Mining Published by Taylor & Francis on behalf of the Institute

To evaluate the antioxidant activity of flower extract of Artabotrys hexapetalus were tested for invitro free radical scavenging assays, such as total antioxidant capacity, Nitric oxide radical, reducing ability and scavenging of hydrogen peroxide. Artabotrys hexapetalus flower extract effectively scavenged free radicals at all different concentrations and showed its potent antioxidant activity. Results were compared to standard antioxidant such as ascorbic acid.

Mushrooms have been a food supplement in various cultures and they are cultivated and eaten for their edibility and delicacy. They fall between the best vegetables andanimal protein source. Mushroom consider as a distinctive food since the beginning of human evolution. As a fruit body of an edible white rotungus, oyster mushroom belongs to Pleurotus, Pleurotaceae, Agaricales and Basidiomycota. One species of oyster mushroom Pleurotus platypus spawn were produced by using sorghum grains. The mushroom was grown on paddy straw and average yield was calculated 410g and 273g in first and second harvesting. Whereas average yield 910g was recorded. The biochemical analysis confirms that the protein, carbohydrate, lipid and amino acid in Pleurotus platypus. The total protein was 9.1 mg/g, carbohydrate 6.7mg/g, lipid 1.27 mg/g and amino acid 1.35 mg/g were recorded. © 2015, Journal of Chemical and Pharmaceutical Research. All rights reserved.

Soil is a complex ecosystem, soil beneath our foot constitute rich source of microbes whose abundance are affected by both biotic and abiotic factors. Biodiversity might help sustain multiple ecosystem functions. Fungi fulfill a range of important ecological functions, yet current understanding of fungal biodiversity in soil is limited. Soil fungi have pivotal ecological roles as decomposers, pathogens and symbionts. This study highly intend to examine the physical and chemical characteristics of the soil samples and to identify as many fungi as possible present in the four seasons of soil collected from major soil types of Thiruvarur district, Tamil Nadu. The population mean density of fungi varied from 99.99 × 10-3 cfu/g with the maximum in the samples was collected during post monsoon and monsoon season. The percentage of contribution of the individual species to the total fungal population at all the seasons showed variation. At the maximum percentage of contribution was found in Trichoderma harzianum. The occurrence of different fungal species fluctuated due to ecological and biological factors of the soil and enhanced the sufficient knowledge to the farmers for the conservation of soil properties, management of soil microbial diversity and the development of sustainable agricultural system.

Objective: Capparis spinosa L. (Caper) is a perennial spiny bush that bears rounded, fleshy leaves and big white to pinkish-white flowers. It is native to the Mediterranean region and growing wild on walls or in rocky coastal areas throughout India. Even though it has been used in traditional Indian system of medicines for various human diseases, the summation of its medicinal properties is lacking. Hence, the present review focused to provide collective information regarding the medicinal value of C. spinosa. Methods: Literatures were collected from online resources like Scopus, Sciencedirect etc., related to the pharmacological activities of Capparis spinosa and the available information were summarized and given in the review. Results: C. spinosa has anthelminthic, cytotoxic, anti-inflammatory, antiarthritic, antioxidant, antibacterial, antifungal, antiviral, cardiovascular, chondroprotective, antidiabetic, hypolipidemic, antiallergic and antihistaminic, immunomodulatory, anticarcinogenic, and antihepatotoxic activity. The phytochemicals identified in this plant were lipids, alkaloids, glucocapperin, and polyphenols. Conclusion: This review attempts to encompass the available literature on C. spinosa with respect to its pharmacognostic characters, chemical constituents, nutritional characters, various pharmacological activities, traditional uses, and modern use. © 2016, Innovare Academics Sciences Pvt.

Betel quid (BQ) chewing is ancient, socially acceptable habit in India. A mixture of betel leaf, areca nut, and tobacco chewing is used in many parts of India. The aim of our study is to assess the biochemical changes of a mixture of betel leaf, areca nut, and tobacco users. A total of 25 male patients aging ≥45 years. Among them 5 had no habit of chewing betel quit with or without tobacco and 20 possessed the habit for BQ chewing. A significant difference in biochemical levels among control and chewers. The level of plasma glucose, serum enzymes such as alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, serum cholesterol, high-density lipoprotein cholesterol, triglycerides urea, and creatinine were found to be increased and the protein level was decreased chewers when compared to non-chewers. BQ chewing is significantly associated with a variety of health problems liver marker enzymes, renal marker, lipid profile, glucose in the present study. © 2015, Asian Journal of Pharmaceutical and Clinical Research.

Objective: The present study has been designed to produce ultraviolet-visible (UV-VIS) and Fourier transform-infrared (FT-IR) spectrum profile of rhizome of Drynaria quercifolia. Methods: The methanol extract was examined under visible and UV light for proximate analysis. The extract was scanned in the wavelength ranging from 100 to 1100 nm. FT-IR spectrum was also used to identify the functional groups of active components based on their peak values in the region of infrared radiation. Results: The result showed the peaks at 279 and 214 nm with the absorption 0.921 and 2.607, respectively. Result: The result of FT-IR profile confirmed the presence of amines, alkanes, denatured amines, alkynes, carboxylic acids, alkenes, alkanes and alkenes which shows the peaks at 3436, 2197, 2360, 2125, 1772, 1626, 1447 and 815, respectively.

Caesalpinia bonducella L. belongs to the family Caesalpiniaceae is distributed throughout India and commonly known as Kazhichikkai in Tamil. In the present study, attempts were made to assess the physicochemical, phytochemical, nutritional and pharmacological properties of C. bonducella seeds. Powder microscopy revealed characteristics features of C. bonducella seeds. Physicochemical properties such as foreign matter (0.97%), loss on drying (8.83%), total ash (3.37%), solubility in water (28.8%) and extractive value in water (6.7%) were revealed by the sample. Phytochemical analysis revealed the presence of alkaloid (0.12 mg g-1), phenol (0.60 mg g-1), flavonoid (0.33 mg g-1), tannin (4.90 mg g-1) and lignin (74.7 mg g-1). The nutritional profile of C. bonducella revealed the presence of carbohydrate (18.4 mg g-1), proteins (17.6 mg g-1), fat (3.6 mg g-1), fibre (3.3 mg g-1) and energy value (73.6 kcal). Presence of different phytochemicals was confirmed in the hexane and chloroform extracts of C. bonducella using HPTLC and GC-MS techniques. The aqueous extract (1000 μg mL-1) recorded anti-inflammatory activity in terms of inhibition of protein denaturation (94.15%), inhibition of protease activity (32.40%) and HRBC membrane stabilization (81.66%). Strong antioxidant activity was noticed in aqueous extract based on the results of DPPH radical scavenging (90%) and lipid peroxidation (99.69%) assays, which are higher than that of BHT standard. Thus the present investigation provides scientific evidence for the folk-lore claims for medicinal value of C. bonducella seeds. © 2016 S. Manikandaselvi et al.
