The present work evaluated the chemical composition and the DNA protective effect of the essential oils (EOs) from Lippia alba against bleomycin-induced genotoxicity. EO constituents were determined by Gas Chromatography/Mass Spectrometric (GC-MS) analysis. The major compounds encountered being citral (33% geranial and 25% neral), geraniol (7%) and trans-β-caryophyllene (7%) for L. alba specime...

In order for a lignocellulosic bioenergy feedstock to be considered sustainable, it must possess a high rate of growth to supply biomass for conversion. Despite the desirability of a fast growth rate for industrial application, it is unclear what effect growth rate has on biomass composition or saccharification. We characterized Klason lignin, glucan, and xylan content with response to growth i...

A reappraisal is made of the Anthurium Schott species with palmately divided leaves with 3 or more segments free to the base (i.e. palmatisect leaves), previously recognized as section Dactylophyllium Schott (Engler), as well as those species with 5 or more segments united at the base (i.e. palmatifid leaves), formerly placed in section Schizoplacium Schott (Engler). New molecular data indicate...

The hexanic extract composition of two populations of Lippia graveolens growing in an arid zone in the Tehuacán-Cuicatlán Valley (Zapotitlán Salinas, Puebla), Central Mexico, in different seasons of the year, and in contrasting conditions of ecological disturbance has been studied by GC and GC-MS. Regarding to the composition of these extracts, qualitative differences among the two populations ...

Kaliszewskia ochoai gen. nov., sp. nov. (Tarsonemidae: Tarsoneminae: Tarsonemini) is described from adult females, collected on Blepharocalix salicifolius (Kunth) O.Berg and Plinia sp. (Myrtaceae), from the Atlantic Forest in Brazil.

Species boundaries in Lippia asperrima and turnerifolia complex (Verbenaceae)
 The specific of L. are discussed. contermina is accepted as segregated asperrima, while modesta Morongii rehabilitated the synonym turnerifolia. Lantana ovata var. hirsuta recognized new synonymies contermina, whereas trachyphylla treated cospecific modesta, asperima f. angustifolia reduced under Morongii. All s...

This study includes 10 samples isolated from a different source. research paper was to the antibacterial activity and antibiofilm of an alcoholic extract Lemon Myrtle (Backhousia citriodora) leaves, against clinical isolates Pseudomonas aerogenoza. Isolates were diagnosed by VITEK-2 compact system (PCR). The capacity produce biofilm tested using Microtiter plate technique (96 wells). results sh...
