Chronic diarrhea may affect ~5% people industrialized countries, and acute or chronic infectious remains important cause morbidity developing countries. The Crassulaceae family plants includes Bryophyllum pinnatum (Lam.) Oken plant, which well renowned for ...

The zoospores of Phytophthora sojae are chemotactically attracted to the isoflavones genistein and daidzein that are released by soybean roots. In this study we have examined the response of P. sojae zoospores to a wide range of compounds having some structural similarity to genistein and daidzein, including isoflavones, flavones, chalcones, stilbenes, benzoins, benzoates, benzophenones, acetop...

This review presents the currently known phytochemical constituents of the genus Lantana; a total of 160 natural compounds have been included. Lantana is free from diterpenoids and rich in essential oils. Monoterpenes, triterpenes, flavones coumarin, steroids, iridoid glycosides, and caffeic acid derivatives are reported from Lantana. Triterpenes and flavones are the more common secondary metab...

Clusia fluminensis Planch. & Triana (Clusiaceae Lindl.) is a native species found in regions of high luminosity and water restriction. The aim of this study was to evaluate the antioxidant activity of Clusia fluminensis crude extracts through the scavenging of the stable free radical DPPH, and the determination of flavones and flavonols content in these extracts. The fruit acetonic extract show...

Baccharis trinervis (Lam.) Pers. (Family: Asteraceae alt. Compositae), used in South American folk medicine as an antiseptic, digestive and to treat snake-bites (Duke, 1999), is widely distributed from Mexico to Argentina (USDA-ARS-GRIN database, 1999). Plant material was collected from Costa Rica and supplied by Biotics Limited, University of Sussex, Brighton, UK. A voucher specimen (MNL10118)...

Helicases couple the hydrolysis of nucleoside triphosphates (NTPs) to the unwinding of double-stranded nucleic acids and are essential in DNA metabolism. Thus far, no inhibitors are known for helicases except heliquinomycin isolated from Streptomyces sp. As the three-dimensional structure of the hexameric replicative DNA helicase RepA encoded by the broad host-range plasmid RSF1010 is known, th...

The present study was designed to characterise and quantify the major phenolic constituents in healthy leaves infected with Xanthomonas campestris pv. juglandis. A comparison among six different cultivars: 'Fernor', 'Fernette', 'Franquette', 'Rubina', 'Sava' 'Krka', same agricultural, geographical climatic conditions, made. Liquid chromatography coupled a mass spectrometer (HPLC-MS/MS) used ide...
