Comparison of the preventive activity of isorhamnetin glycosides from atsumi-kabu (red turnip, Brassica, campestris L.) leaves on carbon tetrachloride-induced liver injury in mice.
Isorhamnetin 3-O-glucoside, which was contained together with isorhamnetin 3,7-di-O-glucoside in atsumi-kabu leaves, suppressed increases in the plasma ALT and AST activities of mice with liver injury induced by the injection of carbon tetrachloride, but no suppression by isorhamnetin 3,7-di-O-glucoside was apparent. This result indicates that the release of glucose at the 7-position in isorham...
متن کاملEnzymatic degradation of Congo Red by turnip (Brassica rapa) peroxidase.
The enzyme peroxidase is known for its capacity to remove phenolic compounds and aromatic amines from aqueous solutions and also to decolourize textile effluents. This study aims at evaluating the potential of a turnip (Brassica rapa) peroxidase (TP) preparation in the discolouration of textile azo dyes and effluents. An azo dye, Congo Red (CR), was used as a model pollutant for treatment by th...
متن کاملEffects of Temperature on Systemic Infection and Symptom Expression of Turnip mosaic virus in Chinese cabbage (Brassica campestris)
Using the Chinese cabbage (Brassica campestris) cultivar 'Chun-goang' as a host and turnip mosaic virus (TuMV) as a pathogen, we studied the effects of ambient temperature (13°C, 18°C, 23°C, 28°C and 33°C) on disease intensity and the speed of systemic infection. The optimal temperature for symptom expression of TuMV was 18-28°C. However, symptoms of viral infection were initiated at 23-28°C an...
متن کاملEffect of Diffusion on Discoloration of Congo Red by Alginate Entrapped Turnip (Brassica rapa) Peroxidase
Enzymatic discoloration of the diazo dye, Congo red (CR), by immobilized plant peroxidase from turnip "Brassica rapa" is investigated. Partially purified turnip peroxidase (TP) was immobilized by entrapment in spherical particles of calcium alginate and was assayed for the discoloration of aqueous CR solution. Experimental data revealed that pH, reaction time, temperature, colorant, and H2O2 co...
متن کاملSequence of a Brassica campestris myrosinase gene.
Myrosinase (thioglucoside glucohydrolase, P-thioglucosidase, EC 3.2.3.1) catalyzes the hydrolysis of glucosinolates, a diverse group of sulfur-containing glycosides that are present in a11 the Cruciferae, to D-G~c, sulfur, and a variety of volatile compounds including thiocyanates, isothiocyanates, and nitriles (Fenwick et al., 1983). Normally, myrosinase and the glucosinolates are kept sequest...
