Chaudhary Charan Singh Haryana Agricultural University, Hisar

Chaudhary Charan Singh Haryana Agricultural University popularly known as HAU, is one of Asia's biggest agricultural universities, located at Hisar in the Indian state of Haryana. It is named after India's seventh Prime Minister, Chaudhary Charan Singh. It is a leader in agricultural research in India and contributed significantly to Green Revolution and White Revolution in India in the 1960s and 70s. It has a very large campus and has several research centres throughout the state. It won the Indian Council of Agricultural Research's Award for the Best Institute in 1997. HAU was initially a campus of Punjab Agricultural University, Ludhiana. After the formation of Haryana in 1966, it became an autonomous institution on February 2, 1970 through a Presidential Ordinance, later ratified as Haryana and Punjab Agricultural Universities Act, 1970, passed by the Lok Sabha on March 29, 1970. A. L. Fletcher, the first Vice-Chancellor of the university, was instrumental in its initial growth.

    In vitro antioxidant and antimicrobial activities of mustard extracts
    (CCSHAU, Hisar, 2021-09) Jyoti; Nisha Kumari
    Mustard is the third most important oilseed crop after oil palm and soybean. Although mustard is widely used as edible oil and condiment, the residue left after oil extraction is popularly used as livestock and poultry feed with excellent protein quality. However, the information regarding antioxidative and antimicrobial potential of mustard seed meal is still scanty. Therefore, the objective of the present study was to extract the polyphenols from brown and yellow mustard seed meal with different solvents i.e 80% methanol, 80% ethanol, 80% acetone and 80% isopropanol. Each extract was analysed for antioxidant potential using DPPH and ABTS scavenging activity, ferric ion reducing antioxidant power (FRAP) assay, total antioxidant activity, iron chelating activity and β-Carotene content. The 80% acetone extracted maximum polyphenols followed by 80% ethanol, 80% methanol and 80% isopropanol. Brown mustard exhibited a higher amount of polyphenols as compared to yellow mustard. Yellow mustard exhibited higher antioxidant potential in terms of DPPH and ABTS scavenging activity, ferric ion reducing antioxidant power, iron chelating activity and β-Carotene content. Correlation analysis indicated a negative association between total phenolic content and DPPH, ABTS and FRAP. Antimicrobial potential was evaluated against two gram-negative (Escherichia coli and Xanthomonas campesteris), two gram positive (Bacillus cereus and Lactobacillus plantarum) bacteria and three fungi (Fusarium oxysporum, Macrophomina phaseolina and Candida albicans). Yellow mustard exhibited higher antibacterial activity while brown mustard had higher antifungal activity. Both the mustard seed meal extracts were ineffective against probiotic bacteria Lactobacillus plantarum. Gallic acid, caffeic acid, ferulic acid and sinapic acid were identified in mustard seed meal by HPLC analysis.
