detection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
The antioxidant properties of garlic compounds: allyl cysteine, alliin, allicin, and allyl disulfide.
Garlic and garlic extracts, through their antioxidant activities, have been reported to provide protection against free radical damage in the body. This study investigated antioxidant properties of garlic compounds representing the four main chemical classes, alliin, allyl cysteine, allyl disulfide, and allicin, prepared by chemical synthesis or purification. Alliin scavenged superoxide, while ...
متن کاملKinetic Study of Reaction between Allyl Compounds of Mg and Ethylene: Computational Investigation
The reactions of propenyl magnesium halides with ethylene were studied using ab initio calculations. The structure of the transition state and the ground state were evaluated and obtained the structural properties, theoretical thermodynamic and kinetic data i.e. rate constants of the reactions. The methods used for calculations are RHF, B3LYP and MP2 with 6-31G* b...
متن کاملPreparation of X-allyl-dl-homocysteine and Related Compounds and Tests of Their Growth Effects in Rats
Since the original report on ethionine (I) by Dyer (I), numerous studies have demonstrated the inhibitory properties of this analogue of methionine on growth in higher animals and microorganisms (cf. Woolley (a)), and even on the propagation of viruses (3, 4) and the reversal of these inhibitions by methionine. A number of pathological effects of ethionine on different organs have also been rep...
