Brassica rapa is an important crop species that produces vegetables, oilseed, and fodder. Although many studies reported quantitative trait loci (QTL) mapping, the genes governing most of its economically important traits are still unknown. In this study, we report QTL mapping for morphological and yield component traits in B. rapa and comparative map(More)
In the present study, an essential fatty acid, ethyl linoleate (ELA), was isolated from the cloves of Allium sativum, and its structure was elucidated by NMR and GC-MS analyses. In vitro systems were used to evaluate the anti-inflammatory activity of ELA. Our results indicate that ELA down-regulates inducible nitric oxide synthase (iNOS) and(More)
Diallyl disulfide (DADS) is a major component of an oil-soluble allyl sulfide garlic (Allium sativum) derivative, which has been shown to exert a potential for anti-cancer activity. However, the biochemical mechanisms underlying DADS-induced anti-invasiveness and anti-metastasis have not been thoroughly studied. In this study, we investigated the effect of(More)
The delta(5)-3-ketosteroid isomerase from Pseudomonas putida biotype B has been crystallized. The crystals belong to the space group P2(1)2(1)2(1) with unit cell dimensions of a = 36.48 angstrom, b = 74.30 angstrom, c = 96.02 angstrom, and contain one homodimer per asymmetric unit. Native diffraction data to 2.19 Angstrom resolution have been obtained from(More)
Phytochemical constituents, such as alliin, vitamin C, total phenol and total flavonoid, content of free sugars, and antioxidant activity of 19 garlic lines and cultivars [six parental lines, three controlled cultivars, five cultivars for regional adaptation test (RAT cultivars), and five new cultivars, released by NIHHS for commercialization] cultivated at(More)
The aim of this study was to quantify the contents of individual quercetin glycosides in red, yellow and chartreuse onion by High Performance Liquid Chromatography (HPLC) analysis. Acid hydrolysis of individual quercetin glycosides using 6 M hydrochloric acid guided to identify and separate quercetin 7,4'-diglucoside, quercetin 3-glucoside, quercetin(More)
This study investigated the effects of (10Z)-1-[(5Z,8Z)-tetradeca-5,8-dienoyloxy]-3-[(Z)-tetradec-8-enoyloxy]propan-2-yl hexadec-10-enoate (TTPH) from garlic on the inducible nitric oxide synthase (iNOS) and cycloxygenase-2 (COX-2) systems in lipopolysaccharide (LPS)-stimulated RAW264.7 macrophages. The TTPH dose-dependently reduced nitrite accumulation and(More)
