In vitro Antifungal and Phytotoxic Study of Metabolites Extracted from Aspergillus flavus
Aspergillus flavus is one of the most important plant as well as human pathogen. A. flavus, has gained worldwide attention for its industrial use and toxigenic potential. Besides their pathogenicity, A. flavus produces a wide range of secondary metabolites, used in food and pharmaceuticals industry. To determine the bioactivity of A. flavus, it was isolated from soil of Khyber Pukhtunkhwa, Paki...
متن کاملPhytotoxic secondary metabolites and peptides produced by plant pathogenic Dothideomycete fungi.
Many necrotrophic plant pathogenic fungi belonging to the class of Dothideomycetes produce phytotoxic metabolites and peptides that are usually required for pathogenicity. Phytotoxins that affect a broad range of plant species are known as non-host-specific toxins (non-HSTs), whereas HSTs affect only a particular plant species or more often genotypes of that species. For pathogens producing HST...
متن کاملA survey of phytotoxic microbial and plant metabolites as potential natural products for pest management.
Phytotoxic microbial metabolites produced by certain phytopathogenic fungi and bacteria, and a group of phytotoxic plant metabolites including Amaryllidacea alkaloids and some derivatives of these compounds were evaluated for algicide, bactericide, insecticide, fungicide, and herbicide activities in order to discover natural compounds for potential use in the management and control of several i...
متن کاملPhytotoxic compounds from Flourensia cernua.
Bioassay-directed fractionation of a CH(2)Cl(2)-MeOH (1:1) extract of the aerial parts of Flourensia cernua led to the isolation of three phytotoxic compounds, namely, dehydroflourensic acid (1), flourensadiol (2) and methyl orsellinate (3). Dehydroflourensic acid is a new natural product whose structure was established by spectral means. In addition, the known flavonoid ermanin and seven hithe...
متن کاملPhytotoxic Eremophilanes from Ligularia macrophylla.
Systematic bioassay-guided fractionation of the methylene chloride extract of the roots from Ligularia macrophylla was performed to identify both phytotoxic and antifungal compounds. Four phytotoxic eremophilanes (furanoeremophilan-14beta,6alpha-olide, 6beta-angeloyloxy-10beta-hydroxyfuranoeremophilane, eremophil-7(11)-ene-12,8alpha;14beta,6alpha-diolide, and 3alpha-angeloyloxybakkenolide A) an...
