The present work describes the study of biosynthesis of pyranocoumarins in Citrus sinensis and Citrus limonia. Coumarins, like other phenylpropanoids, have biosynthetic origin in p-hydroxy cinnamic acid and their great ...

PART I: Polymeric nanoparticles and bioassay-guided phytochemical investigation of Trichilia elegans e Trichilia catigua (Meliaceae) for the control of leaf-cutting ants Leaf-cutting ants are known as severe agricultural ...

Leaf-cutting ants are known to be a serious pest for agriculture due to the high amounts of vegetal matter from crops used by them in order to cultivate a symbiotic fungus on which they rely for food and enzymes. The ...

The study of phytopathogenic fungi Alternaria alternata has improved the chemical of this micro-organism. The fungus was grown up in large scale incubated in rice medium for 26 days. After grown period was interrupted an ...

This paper describes the search and identification of probable biomarkers related to defense mechanism triggered by the plants to the infection process of Xylella fastidiosa, bacterium that causes Citrus Variegated Chlorosis ...

This work describes sixteen substances isolated by C. limonia: xanthyletin, seselin, xanthoxyletin, trans-kellactone, trans-decursidinol, junosmarin, scopoletin, isoscopoletin, demethylsuberosin, xanthoarnol, clausarin, ...

The search for new substances with bioactive potential is the target of numerous studies inserted in the chemistry of natural products, since it involves the isolation, the structural elucidation, as well as the action ...
