In the present investigation, the antioxidant activity and free radical scavenging activity of Crambe cordifolia plant were spectrophotometrically studied. Free radical scavenging activity was determined by DPPH method and the obtained IC value was 1106.65 μg/mL. For comparison, the IC value of standard ascorbic acid 50 50 was 21.69 μg/mL. Antioxidant activity was determined by phosphomolybdate...

Photolysis and photocatalysis of Lauth's violet using nano-titanium dioxide at various aqueous buffer and non-buffer pHs. The effects of some various operating parameters such as initial dye concentration, medium pH, illumination time and catalyst amount have been investigated in a photoreactor equipped with high pressure mercury lamp. Spectrophotometric methods supported that the dye is al...

The catalyst system prepared in situ from iron(III) salts, tris(2-pyridylmethyl)amine and a base readily catalyses the intradiol dioxygenation of pyrocatechol in methanol, to primarily afford the half-methyl ester of muconic acid. Dimethyl adipate is obtained by the subsequent, one-step catalytic hydrogenation/esterification, thus providing a green route to this important nylon precursor.

Aluminium (Al) is a phytotoxic element affecting the growth and yield of many crop plants, especially in the tropics. Yet, some plants are able to accumulate high levels of Al. The monogeneric family Symplocaceae represents an Al accumulating family including many tropical and evergreen species with high Al levels in their above ground plant tissues. It is unclear, however, whether Al accumulat...

background the treatment of onychomycosis is a challenge and infections are typically more severe and difficult to treat in toenails than in fingernails. objectives the current study aimed to investigate the fungicidal effect of ultraviolet radiation on the growth of dermatophytes isolated from nails. patients and methods samples from patients with clinical manifestations of onychomycosis were ...
