  • Brassica juncea is a polyphenols enriched edible plant, with diverse medicinal uses of different parts of which have been mentioned in the Ayurveda. The effects of 10 daily oral doses (100, 200, and 400 mg/kg/day) of a methanolic Brassica juncea leaf extract in rat models of anxiety using nondiabetic and alloxan-diabetic rats were quantified. In all the three behavioural tests used, i.e. elevated plus maze, open field, and social interaction tests, anxiolytic-like activity of the extract was observed in the diabetic animals only. Quantitatively, the efficacy of the highest tested dose of the extract in these tests was always less than those observed after its lower ones. These observations provide further experimental evidences for the conviction that Brassica vegetables could as well be useful for combating diabetes associated mental health problems.

  • The ethanol extract of leaf mustard(Brassica juncea) exhibiting high antimicrobial activities was fractionated in the order of hexane, chloroform, ethylacetate and butanol fractions to test antimicrobial activity. The highest antimicrobial activity for the bacteria tested was found in the ethylacetate fraction, but a lesser extent in the butanol fraction. In contrast to antimicrobial activity for the bacteria, both ethylacetate and butanol fractions showed weak antimicrobial activity for yeasts. Unknown compound A in the ethylacetate fraction which exhibited a strong antimicrobial activity was isolated by silica gel column chromatography and HPLC, and exhibited 9 times more antimicrobial activity than the ethylacetate fraction.

  • This study was performed to evaluate the remediation efficiency by Helianthus annuus, Brassica juncea and Brassica campestris on the soil contaminated with nickel, zinc and lead, respectively. The growth rates fell down under 60% in the condition of over 700 mg/kg of zinc for Brassica campestris, 300 mg/kg of lead for Helianthus annuus, and 150 mg/kg of nickel for Brassica juncea on the basis of heavy metal concentration in the soil, because of its toxicity. Also, the hyperaccumulators showed the maximum heavy metal contents in their biomass after 90 days of cultivation. The accumulated heavy metal content per kilogram of hyperaccumulator was 0.65 mg of nickel in Brassica juncea, 0.14 mg of zinc in Brassica campestris, and 0.06 mg of lead in Helianthus annuus, respectively. Additionally, 73.2% of nickel accumulated in Brassica juncea and 95.1% of zinc accumulated in Brassica campestris were concentrated in the upper site of crop like stem and leaves. However, in the case of Helianthus annuus, 83.7% of lead was accumulated in the root.

  • Pseudomonas aeruginosa $GRC_2$, siderophore-producing strain, inhibited growth of Macrophomina phaseolina in vitro and reduced charcoal rot in seeds of Brassica juncea in field when coated with adaptive strains. P. aeruginosa $GRC_2$ and Azotobacter chroococcum $AC_1$ produced indole-3-acetic acid and solubilized insoluble phosphate. A. chroococcum $AC_1$ fixed nitrogen asymbiotically. Urea and diammonium phosphateadaptive variant strains of P. aeruginosa and A. chroococcum strongly inhibited M. phaseolina in comparison to parental strains. Bacterization of seeds induced seed germination, seedling growth, and enhanced yield of B. juncea by 10.87% as compared to full doses of urea and diammonium phosphate. Both adaptive strains of chemical fertilizers aggressively colonized roots, showing effectiveness to growth and developments of B. juncea.

  • The aim of the present study was to assess the importance of siderophore producing rhizobacteria on the growth of Brassica juncea under chromium stress. Pseudomonas sp. (A4) produced an iron chelating substance siderophores in iron deficient medium. Under chromium stress condition Pseudomenas sp. (A4) markedly increased the root and shoot length and also biomass of Brassica juncea as compared to Pseudomonas sp. (A3). This plant growth promotion has been related to the microbial production of siderophores.

  • The composition of essential oils in the leaves of three cultivars (Ban-Chung-Gat, Chung-Gat and Dolsan-Gat) of Brassica juncea L. were analyzed and their antifungal activity were investigated in this study. Allyl isothiocyanate, 2-phenyl ethyl isothiocyanate, 4-isothiocyanato-1-butene, 5-methyl isothiazole, benzene acetaldehyde, benzene propane nitrile and beta-ionone have been identified in all of the experimented oils. The main component of the oils from Ban-Chung-Gat and Chung-Gat was 2-phenyl ethyl isothiocyanate while allyl isothiocyanate was the representing compound in the oil of Dolsan-Gat. The antifungal activities of the oils were tested by micro broth dilution method and disc diffusion method. As the result the oils exhibited significant inhibiting activities against Aspergillus niger, A. flavus, Trichoderma viride, Candida albicans, C. utilis, C. tropicalis, Cryptococcus neoformans, Trichosporon mucoides, Trichophyton tonsurans and Geotrichum capitatum.

  • The Anthocyanins in the Korean native Brassica juncea, which were favorably used directly for food or as condiments, were investigated. Two kinds of anthocyanin were separated from Korean native Brassica juncea by T.L chromatography and then Robinson test, spectrophotometry, T.L. chromatography, partial hydrolysis were tested for the structural elucidation of these two anthocyanins. It was known that two pigments were peonidin-3-glucoside and peonidin-3-galactoside.
