Pacific Science Review A: Natural Science and Engineering

Effective removal of organic pollutants from wastewater becomes notable research because of its ecological and environmental importance. In the present study Andrographis echioides leaf extract was used for the synthesis of calcium hydroxide nanoparticles (Ca(OH)2-NPs) from calcium oxide as the calcium source. The secondary metabolites present in the plant source act as a capping agent for the formation Ca(OH)2-NPs. Further NPs were applied for photocatalytic degradation. The intention of the approach is to be low-cost preparation and easy degradation (degradation of dye without any effect) to the environment. The synthesized Ca(OH)2-NPs was characterized by X-ray diffraction, Fourier transform infrared spectroscopy, ultra violet diffuse reflectance spectroscopy, energy dispersive X-ray spectroscopy, zeta potential and high-resolution transmission electron microscopy. The photocatalytic degradation of methylene blue (dye pollutant) studied under three different light sources such as UV, visible and sun light using Ca(OH)2-NPs. Degradation efficiency of Methylene blue dye examined under UV–Vis spectroscopy. Degradation percentage of Ca(OH)2-NPs under UV, visible and sunlight are (98.96, 97.52 and 96.38%) respectively. The overall study suggests that Ca(OH)2-NPs exhibit excellent photocatalytic property against UV, visible and sunlight. © 2017, Springer Science+Business Media, LLC.

<p>Objective: To evaluate the ethyl acetate, methanol and aqueous extracts of dried fruiting bodies of Pleurotus eous for its anti-platelet activity on human volunteer’s blood. And also to analyze the free radical scavenging property of the extracts of P.eous by using various in vitro models. Methods: Anti-platelet activity of dried fruiting bodies of P.eous was evaluated by in vitro model using blood platelets. Inhibition of platelet aggregation was monitored after pre-incubation of platelets with the crude extracts of mushroom P.eous. Antioxidant activities of extracts of P.eous were evaluated by different in vitro experiments, namely, 1, 1-diphenyl-2-picryl hydrazyl (DPPH), superoxide, hydroxyl radical and lipid peroxide radical models. Results: Crude extracts of mushroom P.eous inhibited platelet aggregation dose-dependently which was induced by adenosine diphosphate (ADP). At a maximum concentration of 10 mg/mL, methanol extract effected 64.02% inhibition of lipid per-oxidation and 50.12% scavenging effect on superoxide anion radical. Aqueous extract of P.eous have shown 69.43% chelating ability on ferrous ions, 24.27% scavenging effect on hydroxyl radical and 49.57% scavenging effect on DPPH radical at 10 mg/mL. Increasing concentrations of the extract were found to cause progressively decreasing of the intensity of absorbance. Conclusions: Anti-platelet effects could be related in part to the polyphenolic compounds present in the extracts. Antioxidant activity results indicated the free radical scavenging property of the extracts of P.eous which might be due to the high content of phenolic compounds and flavonoids. © 2015, Chinese Association of the Integration of Traditional and Western Medicine and Springer-Verlag Berlin Heidelberg.</p>

<h3>Objective</h3><p>To evaluate the analgesic activity of the ethyl acetate, methanol and aqueous extracts of <i>Pleurotus eous (P. eous)</i> mushroom.</p><h3>Methods</h3><p>The dried fruiting bodies were extracted with ethyl acetate, methanol and water. The analgesic effect of extracts of <i>P. eous</i> were investigated at doses 250 500 and 1 000 mg/kg body weight, using acetic-acid induced writhing, hot-plate, tail immersion and tail-clip tests.</p><h3>Results</h3><p><i>P. eous</i> extracts produced significant reduction in number of writhes induced by intraperitoneal injection of acetic-acid (<i>P</i>&lt;0.05). Moreover, in hot-plate and tail immersion test, all the three extracts significantly raised the pain threshold at different time of observation (0-60 min) in comparison with control (<i>P</i>&lt;0.05). In tail-clip test the extracts also caused a significant inhibition of pain at both the doses used (<i>P</i>&lt;0.05).</p><h3>Conclusions</h3><p>The results of present study suggest that extracts of <i>P. eous</i> possess potent analgesic property and could serve as a base for future drugs.</p>
