brassica napus l. and sinapis alba l. are two cruciferous species for which some medicinal uses are mentioned in the iranian, indian and chinese traditional medicine. seed oil of  b. napus has cathartic action, and is either used as such or after partial hydrogenation for cooking, shortening or as margarines. sees of s. alba have also cathartic action and some other medicinal uses but, because ...

volatile constituents of the seed kernel and leaf of cultivated moringa peregrina (forssk.) fiori, agricolt collected after hydrolysis were analyzed by gc and gc/ms. five glucosinolate degradation products which constituted almost the whole isolated oil of the seed kernel were identified to be: isobutyl isothiocyanate (94.0%), isopropyl isothiocyanate (4.9%), sec-butyl isothiocyanate (0.5%), n-...

There have been many studies involving frying of potato chips in various vegetable oils in order to observe the quality of the fried product [1-6]. Frying oils are exposed to extreme environmental conditions (air, water or steam, high temperatures of 140-200 °C), trace metals that result in degradation of the frying oil triacylglycerols by oxidation, polymerization, isomerization, cyclization a...

background: mahyaveh is an iranian salted-fermented fish sauce which due to its high amount of protein has risk of histamine production. this study was carried out to determine effect of zataria multiflora essential oil (eo) on histamine production in mahyaveh. methods: dried anchovies (stolephorus sp.), refined-salt and mustard seed (brassica juncea) were purchased from the local market in ban...

Lignin is an important renewable source of phenolic products. In this study, alkali lignin was depolymerized to produce phenolic compounds. The effects of catalyst, solvent, reaction time, and reaction temperature on the yields of liquid products and volatile fractions were investigated in detail. Compared with the solvents water and octane, alcohols can significantly promote depolymerization o...

Brassicales species rich in glucosinolates are used for biofumigation, a process based on releasing enzymatically toxic isothiocyanates into the soil. These hydrolysis products are volatile and often reactive compounds. Moreover, glucosinolates can be degraded also without the presence of the hydrolytic enzyme myrosinase which might contribute to bioactive effects. Thus, in the present study th...

Dynamic tribochemical processes for dicationic ionic liquid containing a geminal imidazolium cation head group bridged by a poly(ethylene glycol) and a bis(trifluoromethylsulfonyl)imide anion were studied using time-resolved mechanically stimulated gas emission mass-spectrometry (MSGE-MS). In comparison with similar monocationic imidazolium ionic liquids with short alkyl or long polyether side ...
