Background & Aim: Persian shallot (Allium hirtifolium Boiss) with common name of "Musir" is one of the endemic medicinal plants in Iran. Leaves and bulbs with antibacterial, antifungal, anticancer, anti-diabetes and anti-obesity effects are edible parts of this plant. The tissue culture is an influential method to multiply plant productions in order to meet demands of ...

In marine-archaeological oak timbers of the Mary Rose large amounts of reduced sulfur compounds abound in lignin-rich parts such as the middle lamella between the cell walls, mostly as thiols and disulfides, whereas iron sulfides and elemental sulfur occur in separate particles. Synchrotron-based x-ray microspectroscopy was used to reveal this environmentally significant accumulation of organos...

A method was developed to analyze the distribution of sulfur compounds in model sulfur compounds by potentiometric titration, and applied to analyze hydrotreated transformer base oil. Model thioethers were oxidized to corresponding sulfoxides by tetrabutylammonium periodate and sodium metaperiodate, respectively, and the sulfoxides were titrated by perchloric acid titrant in acetic anhydride. T...

Corrosive Sulfur in transformer oil has been the cause of high profile transformer failures in recent years. Oil treatments consisting of copper passivators have been only partially effective. DSI has discovered a multi-step method that has been proven to change oils with corrosive sulfur into non-corrosive status, as well as significantly slowing oxidation and ageing of insulating oil and pape...

The authors attempted to determine if the organic sulfur compounds usually contained in a crude oil could serve as a marker of oil pollution in fish. Eels (Anguilla Japonica Temminck et Schlegel) were maintained in a controlled laboratory environment of water with a suspension of crude oil. Gas chromatography-mass spectrometry and mass chromatography of eel flesh extract showed the presence of ...

Five sulfur-containing flavor compounds were synthesized for the first time by the reaction of 4-ethyloctanoyl chloride with sulfur-containing alcohols or mercaptans. The synthesized compounds are 3-(methylthio)propyl 4-ethyloctanoate, 2-methyl-3-tetrahydro-furanthiol 4-ethyloctanoate, 4-methyl-5-thiazoleethanol 4-ethyloctanoate, 2-furan-methanethiol 4-ethyloctanoate and 2-methyl-3-furanthiol 4...

Sulfuricurvum kujiense Kodama and Watanabe 2004 is the type species of the monotypic genus Sulfuricurvum, which belongs to the family Helicobacteraceae in the class Epsilonproteobacteria. The species is of interest because it is frequently found in crude oil and oil sands where it utilizes various reduced sulfur compounds such as elemental sulfur, sulfide and thiosulfate as electron donors. Mem...

Transition-metal-catalyzed asymmetric synthesis is a powerful and commonly used method for preparing a wide range of enantiomerically pure compounds.1 Among organo-transition-metal compounds, Pd complexes have become indispensable tools for both common and stateof-the art organic synthesis.2 Although a large number of Pd-based catalytic systems have been developed for many kinds of reactions, P...

A protocol for the synthesis of α-alkynylnitrones from 1,3-enynes has been developed. The process is triggered by hydromagnesiation with magnesium hydride (MgH2), which prepared in situ through solvothermal treatment iodide (MgI2) sodium (NaH) tetrahydrofuran. Downstream functionalization resulting propargylmagnesium intermediates organo nitro compounds affords α-alkynylnitrones, could be used ...
