Antifeedant and Toxic Effect of Crude Extract from Flourensia oolepis and their Impact on Nutritional Parameters of Helicoverpa gelotopoeon
(University of Port Harcourt, 2014-12)
Botanical insecticides are one of the environmentally acceptable options for pest management. Extract of Flourensia oolepis (known as chilca), a plant endemic to the province of Córdoba, Argentina, has shown insecticidal ...
Effect of Flourensia oolepis Blake (chilca) Extract on Adults of Helicoverpa gelotopoeon Dyar (Lepidoptera: Noctuidae) and its Parasitoid Archytas sp. (Diptera: Tachinidae)
(Connect Journals, 2014-09)
Indiscriminate use of synthetic insecticides, commonly-used tools for pest control, has been shown to cause irreversible environmental damage. Botanical compounds currently represent ecologically acceptable alternatives. ...
Antifeedant activity of ethanolic extract from Flourensia oolepis and isolation of pinocembrin as its active principle compound
(Elsevier, 2009-12)
The ethanolic extract from Flourensia oolepis aerial parts showed strong antifeedant activity against the pest larvae, Epilachna paenulata, with an antifeedant index (AI%) of 99.1% at 100 μg/cm2. Based on chromatographic ...
The Inhibitory Activity of Plants from Central Argentina on p-Hydroxyphenylpyruvate Dioxygenase: Isolation and Mechanism of Inhibition of a Flavanone from Flourensia oolepis
(Georg Thieme Verlag Kg, 2015-10)
The enzyme 4-hydroxyphenylpyruvate dioxygenase catalyzes the second step in the tyrosine degradation pathway. In mammals, this enzyme is the molecular target of drugs used for the treatment of metabolic disorders associated ...
Phytotoxicity of secondary metabolites isolated from Flourensia oolepis S.F.Blake.
(Wiley Vch Verlag, 2013-07)
The aim of this study was to isolate the active principles of Flourensia oolepis S.F.Blake (Asteraceae), which completely inhibited the germination of Raphanus sativus seeds at 10 mg/ml. Flavanone pinocembrin and sesquiterpene ...
Secretory Structures in Flourensia campestris and F. oolepis: Ultrastructure, Distribution, and (-)-Hamanasic Acid A Secretion
(Scientific Research Publishing, 2015-04-14)
In this work, the localization, density, morphology and ultrastructure of secretory structures in aerial organs of Flourensia campestris (FC) and F. oolepis (FO) (Asteraceae) by means of a combination of light, fluorescence, ...
Potential applications of biochar and terpene-enriched bio-oil produced from a semi-arid native Asteraceae
(Elsevier Science, 2017-06)
Biomass of Flourensia oolepis, a native shrub of the semi-arid central region of Argentina, was treated by vacuum pyrolysis to investigate the potential of this species to be used as a source of energy and chemicals. In ...
Screening for antifungal activity in plants from central Argentina
(Allelopathy Journal, 2010-03)
Ethanolic extracts from aerial parts of 71 native plants from Argentina were tested by bioautography on Thin Layer Chromatography (TLC) for their antifungal effects against pathogenic Fusarium verticillioides. The extracts ...
Antibacterial and cytotoxic activity of compounds isolated from Flourensia oolepis
(Hindawi Publishing Corporation, 2015-12)
The antibacterial and cytotoxic effects of metabolites isolated from an antibacterial extract of Flourensia oolepis were evaluated. Bioguided fractionation led to five flavonoids, identified as 2′,4′-dihydroxychalcone (1), ...
Reproductive biology, seed germination and regeneration of Flourensia DC. species endemic to Central Argentina (Asteraceae)
(Publications Scientifiques Du Museum, Paris, 2017-06)
Our objective was to study reproductive biology, seed germination and regeneration, through morphoanatomical and field observations and controlled experiments, to assess reproductive strategies in six rare Flourensia endemic ...
