After treatment with nitrite, Chinese cabbage showed direct-acting mutagenicity on Salmonella typhimurium TA100 inducing 3100 revertants per g. One of the mutagen precursors that became mutagenic after nitrite treatment was isolated, and identified as indole-3-acetonitrile. After treatment with

Chemical defenses of crucifers: elicitation and metabolism of phytoalexins and indole-3-acetonitrile in brown mustard and turnip.

The metabolism of the cruciferous phytoalexins brassinin and cyclobrassinin, and the related compounds indole-3-carboxaldehyde, glucobrassicin, and indole-3-acetaldoxime was investigated in various plant tissues of Brassica juncea and B. rapa. Metabolic studies with brassinin showed that stems of B.

Effect of boiling on the content of ascorbigen, indole-3-carbinol, indole-3-acetonitrile, and 3,3'-diindolylmethane in fermented cabbage.

The aim of the study was to investigate the effect of the boiling process on the content of ascorbigen, indole-3-carbinol, indole-3-acetonitrile, and 3,3'-diindolylmethane in fermented cabbage. The cabbage was boiled for 5 to 60 min. Boiling resulted in a decrease of the total content of the

Hairy root transformation of Brassica rapa with bacterial halogenase genes and regeneration to adult plants to modify production of indolic compounds.

During the last years halogenated compounds have drawn a lot of attention. Metabolites with one or more halogen atoms are often more active than their non-halogenated derivatives like indole-3-acetic acid (IAA) and 4-Cl-IAA. Within this work, bacterial flavin-dependent tryptophan halogenase genes

SUMMARY Three isoforms of nitrilase were cloned from turnip, Brassica rapa L., and their expression during clubroot development caused by Plasmodiophora brassicae was investigated. The isoforms were designated BrNIT-T1, BrNIT-T2 and BrNIT-T4 based on homology to known nitrilases. BrNIT-T1 and

This paper deals with two categories of compounds having the capacity to inhibit the neoplastic effects of chemical carcinogens on the host. The first are inducers of increased microsomal mixed function oxidase activity. An increasing number of these inducers are being found in natural products.

Helicobacter pylori (H. pylori) infection and high intake of various traditional salt-preserved foods are regarded as risk factors for human gastric cancer. We previously reported that Chinese cabbage contains indole compounds, such as indole-3-acetonitrile, a mutagen precursor.

Dietary constituents of 2 types have been shown to affect the metabolism of chemical carcinogens by the microsomal mixed-function oxidase system. Naturally occurring inducers of increased activity of this system are present in plants. Cruciferous vegetables including Brussels sprouts, cabbage, and

Benzyl isothiocyanate, beta-naphthoflavone, coumarin, alpha-angelicalactone, disulfiram, indole-3-carbinol and indole-3-acetonitrile induced increased glutathione (GSH) S-transferase activity in the liver and small intestine in female ICR/Ha mice. All seven compounds are inhibitors of chemical

In this study we investigated the role of indole-3-acetonitrile, indole-3-carbinol, indole and tryptophan in the formation of N-nitroso compounds in green cabbage extracts. Green cabbage extracts were separated by gel permeation chromatography. Fractions were treated with nitrite, tested for

Stability of glucosinolates and glucosinolate degradation products during storage of boiled white cabbage.

The aim of the study was to investigate the effect of storage on the contents of glucosinolates (GLS) and their degradation products in a boiled white cabbage. A 24h storage at 4 °C resulted in a decrease in GLS content (20-40%, depending on the cooking time applied) in the edible parts. The most

Both white and Savoy-type cabbage added to a semi-purified diet at 25% dry weight and fed to rats ad lib. for 5 days significantly induced ethoxyresorufin (ERR) deethylation in the small and large intestine. Savoy cabbage also induced hepatic activity and, in general, exhibited a greater inducing

Determination of indole-type phytonutrients in cruciferous vegetables.

Consumption of cruciferous vegetables has been associated with a low risk of developing cancer. Indole-type phytonutrients, derived from enzymatic hydrolysis of glucobrassicin, exhibit cancer-preventive properties and occur in all vegetables of the Brassicaceae family. A LC-Q-TOF-MS methodology was
