A New Color Reaction for Soluble Organic Sulfur Compounds

Seed Meal Constituents, Oxazolidinethiones and Volatile Isothiocyanates in Enzyme-Treated Seed Meals from 65 Species of Cruciferae

“…of the 1% solution was spotted on paper for chromatography of the thioureas by the method of Kjaer and Rubinstein (76) in which water-saturated chloroform was the developing solvent. Thiourea derivatives were detected with Grate's reagent (5). Rate of migration of each derivative was related to that of known phenylthiourea (/?ph).…”

Oxidative degradation of ethylenethiourea (ETU) and ETU progenitors by hydrogen peroxide and hypochlorite

“…Compounds form/methanol (5:1) (silica gel) or in isopropyl alcohol/ water (3:7) (cellulose). Spots were visualized using Grote's reagent (Grote, 1931), ferricyanide-nitroprusside, or N,-IV'-dimethylaminocinnamaldehyde in 3:1 ethanol/4 N hydrochloric acid. When chromatographically pure 4,5-[uC]ETU was used as a substrate for oxidation, the products (separated by TLC) were quantified by scintillation counting with appropriate corrections for background and quenching.…”

Onion Flavor and Odor, The Volatile Flavor Components of Onions

“…Identification of Disulfides and Tri-sulfides. The presence of disulfides or trisulfides in a given peak was suggested by odor and established by color development with Grate's reagent and cyanide (6). Peak V (in Figure 1,.4 or B) containing methyl trisulfide and npropyl disulfide could not be resolved VOL.…”
