    Antibacterial activity of Falkenbergia hillebrandii (Born) from the Indian coast against human pathogens

    Manilal1 A, S Sujith2, J Selvin3, C Shakir4, G Seghal Kiran5

    Phyton-International Journal of Experimental Botany, Vol.78, pp. 161-166, 2009, DOI:10.32604/phyton.2009.78.161

    Abstract The antibacterial property of the red algae, Falkenbergia hillebrandii (Born) collected from the southwest coast of India (Indian Ocean) was evaluated against three multidrug resistant human pathogens. Four different solvents: ethyl acetate, dichloromethane, methanol and phosphate buffer saline (PBS) were used with this purpose. Dried samples extracted with methanol showed broadest and highest antimicrobial activity when compared to other solvents. However, PBS extract showed no antibacterial activity. The highly active compounds red alga, F. hillebrandii were fractionated and purified using different chromatographic systems, including reverse phase HPLC and GCMS. The analysis revealed that the most abundant metabolite More >

    Biorefinery of Rice Husk to Obtain Functionalized Bioactive Compounds

    M. Lopretti1,*#, N. Lecot1,2,#, A. Rodriguez3, G. Lluberas1, F. Orozco4, L. Bolaños4, G. Montes De Oca4, H. Cerecetto2, J. Vega-Baudrit4,5

    Journal of Renewable Materials, Vol.7, No.4, pp. 313-324, 2019, DOI:10.32604/jrm.2019.00008

    Abstract The biomass industrialization valorisation of grains and cereals is considered an opportunity for the countries where agro-industrial activity is one of its main economic activities, rendering new higher-value products with a concomitant solution to waste accumulation issues. To that end, in this work we describe and characterise bioactive compounds generation from rice husk by semi-solid fermentation, obtained from 500 g of the material at room temperature and 60% humidity with mixed cultures of Phanerochaete chrysosporium and Gloeophyllum trabeum. The extract was evaluated in different situations: murine mammary tumour cells (4T1), normal cells (NIH 3T3) and More >

    Active compounds of medicinal plants, mechanism for antioxidant and beneficial effects

    Orozco Montes F1, A Vázquez-Hernández2, B Fenton-Navarro1

    Phyton-International Journal of Experimental Botany, Vol.88, No.1, pp. 1-10, 2019, DOI:10.32604/phyton.2019.04525

    Abstract An increased interest in the antioxidant effects of medicinal plants has developed in recent years. Identifying antioxidant compounds present in medicinal plants and elucidating the mechanism by which they prevent oxidation have been the focus of the research community. We performed a systematic and exhaustive review aimed at analyzing the available data regarding the beneficial effects of secondary metabolites in plants. The result of this review is presented as a description of free radicals, as well as cellular and physiological oxidative stress, is provided. The origin and source of antioxidant compounds, and the cellular and More >
