Abstract : The peanut plant (Arachis hypogaea L.), when infected by a microbial pathogen, is capable of producing stilbene-derived compounds that are considered antifungal phytoalexins. In addition, the potential health benefits of other stilbenoids from peanuts, including resveratrol and pterostilbene, have been acknowledged by several investigators. Despite considerable progress in peanut research, relatively little is known about the biological activity of the stilbenoid phytoalexins. This study investigated the activities of some of these compounds in a broad spectrum of biological assays. Since peanut stilbenoids appear to play roles in plant defense mechanisms, they were evaluated for their effects on economically important plant pathogenic fungi of the genera Colletotrichum, Botrytis, Fusarium, and Phomopsis. We further investigated these peanut phytoalexins, together with some related natural and synthetic stilbenoids (a total of 24 compounds) in a panel of bioassays to determine their anti-inflammatory, cytotoxic, and antioxidant activities in mammalian cells. Several of these compounds were also evaluated as mammalian opioid receptor competitive antagonists. Assays for adult mosquito and larvae toxicity were also performed. The results of these studies reveal that peanut stilbenoids, as well as related natural and synthetic stilbene derivatives, display a diverse range of biological activities.

Abstract : Bioassay-guided fractionation of the chloroform extract from the roots of Angelica sinensis led to isolation and characterization of (Z)-ligustilide using direct-bioautography with Colletotrichum species. The structure of (Z)-ligustilide was confirmed by (1)H and (13)C NMR spectroscopy and GC/MS. (Z)-Ligustilide deterred the biting of two mosquito species more effectively than DEET. Three different A. sinensis accessions and one Angelica archangelica root oil were evauated by GC and GC/MS, and the dominant component in A. sinensis was 61-69% (Z)-ligustilide. Two other prominent compounds in A. sinensis oils were 5.7-9.8% (E)-3-butylidene phthalide and 1.5-2.3% (Z)-3-butylidene phthalide. The main constituents that comprised A. archangelica oil were monoterpene hydrocarbons such as 24.5% alpha-pinene, 13.8% delta-3-carene, 10.1% beta-phellandrene, 8.8% p-cymene, 8.4% limonene, and 6.3% sabinene. Phthalides and monoterpene hydrocarbons were determined to be good systematic markers or chemical fingerprints for A. sinensis and A. archangelica root oils. Chemical fingerprinting by GC/MS of A. sinensis also confirmed the misidentification of one A. archangelica sample sold in the Chinese market.

Authors : Nel B, Steinberg C, Labuschagne N, Viljoen A.
Abstract : Fusarium wilt is considered one of the most important diseases of bananas. The disease can only be managed by using resistant cultivars and by preventing its introduction into new fields. The objectives of this study were to evaluate newly available fungicides, in vitro and in vivo, for their efficacy against the responsible pathogen Fusarium oxysporum f.sp. cubense, and to evaluate surface sterilants that could be used for sterilization purposes. Of the fungicides, prochloraz and propiconazole significantly inhibited mycelial growth at concentrations of 1 and 5 μg ml-1, respectively. Benomyl and the demethylation-inhibiting fungicides significantly reduced the disease severity of Foc when applied as a root dip treatment, showing disease reduction up to 80.6%. The results also demonstrated that certain quaternary ammonium compounds are effective as sterilants against Foc and should replace the ineffective sterilants that are currently being used. Further field evaluations of the fungicides are required.

Abstract : Essential oils of Salvia macrochlamys and Salvia recognita were obtained by hydrodistillation of dried aerial parts and characterized by gas chromatography and gas chromatography-mass spectrometry. One hundred and twenty identified constituents representing 97.7% in S. macrochlamys and 96.4% in S. recognita were characterized, and 1,8-cineole, borneol, and camphor were identified as major components of the essential oils. The oils were evaluated for their antimalarial, antimicrobial, and antifungal activities. Antifungal activity of the essential oils from both Salvia species was nonselective at inhibiting growth and development of reproductive stroma of the plant pathogens Colletotrichum acutatum, Colletotrichum fragariae, and Colletotrichum gloeosporioides. S. macrochlamys oil had good antimycobacterial activity against Mycobacterium intracellulare; however, the oils showed no antimicrobial activity against human pathogenic bacteria or fungi up to a concentration of 200 microg/mL. S. recognita oil exhibited a weak antimalarial activity against Plasmodium falciparum.

Abstract : Essential oils from three different Asteraceae obtained by hydrodistillation of aerial parts were analyzed by gas chromatography (GC) and gas chromatography-mass spectrometry (GC/MS). Main compounds obtained from each taxon were found as follows: Arnica longifolia carvacrol 37.3%, alpha-bisabolol 8.2%; Aster hesperius hexadecanoic acid 29.6%, carvacrol 15.2%; and Chrysothamnus nauseosus var. nauseosus beta-phellandrene 22.8% and beta-pinene 19.8%. Essential oils were also evaluated for their antimalarial and antimicrobial activity against human pathogens, and antifungal activities against plant pathogens. No antimalarial and antimicrobial activities against human pathogens were observed. Direct bioautography demonstrated antifungal activity of the essential oils obtained from three Asteraceae taxa and two pure compounds, carvacrol and beta-bisabolol, to the plant pathogens Colletotrichum acutatum, C. fragariae and C. gloeosporioides. Subsequent evaluation of antifungal compounds using a 96-well micro-dilution broth assay indicated that alpha-bisabolol showed weak growth inhibition of the plant pathogen Botrytis cinerea after 72 h.

Abstract : Essential oils from three different Asteraceae obtained by hydrodistillation of aerial parts were analyzed by gas chromatography (GC) and gas chromatography-mass spectrometry (GC/MS). Main compounds obtained from each taxon were found as follows: Arnica longifolia carvacrol 37.3%, alpha-bisabolol 8.2%; Aster hesperius hexadecanoic acid 29.6%, carvacrol 15.2%; and Chrysothamnus nauseosus var. nauseosus beta-phellandrene 22.8% and beta-pinene 19.8%. Essential oils were also evaluated for their antimalarial and antimicrobial activity against human pathogens, and antifungal activities against plant pathogens. No antimalarial and antimicrobial activities against human pathogens were observed. Direct bioautography demonstrated antifungal activity of the essential oils obtained from three Asteraceae taxa and two pure compounds, carvacrol and beta-bisabolol, to the plant pathogens Colletotrichum acutatum, C. fragariae and C. gloeosporioides. Subsequent evaluation of antifungal compounds using a 96-well micro-dilution broth assay indicated that alpha-bisabolol showed weak growth inhibition of the plant pathogen Botrytis cinerea after 72 h.

Title : Antifungal and insect antifeedant 2-phenylethanol esters from the liverwort Balantiopsis cancellata from Chile.
Year : 2005
Volume : 53
Issue : 2
First Page : 247
Last Page : 249
Authors : Labbé C, Faini F, Villagrán C, Coll J, Rycroft DS.
Abstract : A chemical study of a dichloromethane extract of Balantiopsis cancellata led to the isolation of four known 2-phenylethanol esters (1-4) and a phenylethanediol benzoate (5). Antifeedant activity toward Spodoptera littoralis (disk-choice bioassay) and growth inhibition of the phytopathogen Cladosporium herbarum in TLC-bioautography assays were determined. The results show that the antifeedant and antifungal activity of the extract is attributable mainly to the trans-beta-methylthioacrylate 4.

Authors : Oliva A, Meepagala KM, Wedge DE, Harries D, Hale AL, Aliotta G, Duke SO.
Abstract : Bioassay-directed isolation of antifungal compounds from an ethyl acetate extract of Ruta graveolens leaves yielded two furanocoumarins, one quinoline alkaloid, and four quinolone alkaloids, including a novel compound, 1-methyl-2-[6'-(3' ',4' '-methylenedioxyphenyl)hexyl]-4-quinolone. The (1)H and (13)C NMR assignments of the new compound are reported. Antifungal activities of the isolated compounds, together with 7-hydroxycoumarin, 4-hydroxycoumarin, and 7-methoxycoumarin, which are known to occur in Rutaceae species, were evaluated by bioautography and microbioassay. Four of the alkaloids had moderate activity against Colletotrichum species, including a benomyl-resistant C. acutatum. These compounds and the furanocoumarins 5- and 8-methoxypsoralen had moderate activity against Fusarium oxysporum. The novel quinolone alkaloid was highly active against Botrytis cinerea. Phomopsis species were much more sensitive to most of the compounds, with P. viticola being highly sensitive to all of the compounds.

These compounds and the furanocoumarins 5- and 8-methoxypsoralen had moderate activity against Fusarium oxysporum. The novel quinolone alkaloid was highly active against Botrytis cinerea. Phomopsis species were much more sensitive to most of the compounds, with P. viticola being highly sensitive to all of the compounds.
