the antioxidant potential of crude methanol extract (ce) as well as chloroform (cf), ethyl acetate (ef) and n-butanol (nf) soluble fractions of enhydra fluctuans lour, which is widely used in indigenous system of medicine for different purposes, were studied. the antioxidant potential of extract/different fractions were evaluated using different in vitro antioxidant models. in addition, total a...

the majority of the antioxidant and antidiabetic activities of fruits are anthocyanins, a group of polyphenolics that are responsible for the color of many fruits, vegetables and flowers. the harvesting time, storage conditions, maturity, extraction steps etc. are very important for the biological activities based on the alteration of chemical composition. the free radical scavenging and antidi...

the modern lifestyle is characterized by a continuous increase in the demand of ready-to-eat fresh food products subjected to minimal processes prior marketing. attention is drawn towards the effect of this processing on the antioxidant/antiradical properties of two typical italian salads belonging to cichorium genus. four chemical assays (anti-peroxyl radical activity, dpph• assay, metal chela...

objective: to validate the ethno-therapeutic claim of the traditionally used plant jasminum auriculatum (j. auriculatum) in skin diseases, by evaluating its wound healing potential along with its antioxidant and antimicrobial properties; so as to understand their role in wound healing. materials and methods: excision and incision wound models were used to evaluate the wound healing activity on ...

abstract childhood and adolescence are critical periods for the skeleton. mechanical load has then been shown to be one of the best stimuli to enhance not only bone mass, but also structural skeletal adaptations, as both contributing to bone strength. exercise prescription also includes a window of opportunity to improve bone strength in the late pre- and early peri-pubertal period. there is so...

in this study, methanol and ether extracts of five endemic asperula species (rubiaceae) from turkey (a. antalyensis, a. brevifolia, a. pseudochlorantha, a. purpurea subsp. apiculata and a. serotina), used in the traditional system of medicine, were tested for antimicrobial activity by the agar well diffusion method and the broth dilution method. the most active species were asperula brevifolia ...

background tyrosinase is a copper-containing enzyme, which is widely distributed in microorganisms, animals and plants. it is also a key enzyme in melanin biosynthesis, which plays a crucial role in determining the color of mammalian skin and hair. in addition, unfavorable enzymatic browning of plant-derived foods by tyrosinase causes a decrease in nutritional quality and economic loss of food ...

the quantitative structure–activity relationship of a series of novel thiazoline derivatives with anticancer activity has been studied by using the density functional theory by b3lyp/ 6-31g. descriptors of quantum mechanics of 21 thiazoline derivatives with known activity were obtained. multiple linear regressions were employed to model the relationships between molecular descriptors and biolog...

a simple, inexpensive and one-step synthesis route of ag-tio2 nanoparticles by arc discharge method isreported. the resulting nanoparticles were characterized using x-ray diffraction and scanning electronmicroscopy. x-ray diffraction patterns demonstrate dominance of rutile to anatase phase in tio2 andformation of silver metal on tio2 after arc discharge process. scanning electron microscopy im...

methanolic and aqueous extracts of dendrophthoe falcata linn. leaves which belongs to the loranthaceae family, were evaluated through dpph (1, 1-diphenyl -2-picryl-hydrazyl), antilipid peroxidation and nitric oxide scavenging methods to assess the antioxidant activity. methanolic and aqueous extracts of dendrophthoe falcata leaves were also evaluated for their anti-inflammatory activity by carr...
