Phenolic extract of leaves of Basilicum polystachyon (L) Moench was tested for in vitro antimicrobial activity against five bacteria (Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Bacillus subtilis, Micrococcus leuteus) and three fungi (Fusarium oxysporum, Aspergillus niger, Helminthosporium oryzae). Efficacy of organic solvents, methanol and ethanol, as agents for extraction...

Por esse motivo, os métodos de Cooper & Jacob Theis costumam não ser eficazes em traduzir as descontinuidades do meio podem levar a avaliações incertas. A utilização outros métodos, como Warren Root Moench aplicados...

plants of asteraceae are used in traditional medicine and phytotherapy. the two main caffeic acid derivatives, chicoric and caftaric acid which are found in many genus of asteraceae including echinacea exhibit important biological activities. the level of these acids in e. purpurea is affected by many factors such as growing situations, extraction methods, storage conditions and plant age. in t...

A principal components model for analyzing tree -ring data is presented which allows one to examine site heterogeneity and to compose chronologies of a new kind in a conceptually unified and computationally efficient manner. Using this model, one can develop chronologies that correlate better with local climate data than the standard chronology for a site and which can be tested for time stabil...

Weeds compete with crops and are hard to differentiate identify due their similarities in color, shape, size. In this study, the weed species present sorghum (sorghum bicolor (L.) Moench) fields, such as amaranth (Amaranthus macrocarpus), pigweed (Portulaca oleracea), mallow (Malva sp.), nutgrass (Cyperus rotundus), liver seed grass (Urochoa panicoides), Bellive (Ipomea plebeian), were discrimi...
