The antioxidative effect of fullerenes during the peroxidation of methyl linoleate in toluene.
نویسندگان
چکیده
The antioxidative effect of fullerenes C(60) and C(70) was examined by measuring the inhibition of methyl linoleate (MeL) peroxidation in toluene initiated by 2,2'-azobis(2,4-dimethylvaleronitrile) (AMVN). The fullerenes retarded the formation of MeL hydroperoxides and lowered the rate of propagation. The reaction rates of fullerenes with AMVN-derived peroxyl radicals were much higher than that of MeL. These results indicate that fullerenes can act as retarders of lipid peroxidation, though their activity is low compared with that of α-tocopherol.

Abstract: Jasmonic acid and its methyl ester, methyl jasmonate (MeJA), are naturally occurring plant growth regulators, which can affect many physiological and biochemical processes in plants. In present investigation, the effects of methyl jasmonate (0, 1, 10, 100 and 500µM) on some physiological and antioxidative responses in soybean (Glycine max L.) plants were studied. Under MeJA (1 and ...

Abstarct:A simple one-pot synthesis of pyrano[ 2,3-c]pyrazoles was developed by a three-component reaction of various benzaldehydes, malononitrile and 1-phenyl or hydro-3-methyl-1H-pyrazol-5(4H)-one in the presence of N-methyl pyridinium p-toluene sulfonate (NMPyTs) as a catalyst. All of the synthesized compounds were identified by IR, 1H NMR, 13C NMR and mass spectroscopy techniques. In the me...
