They are used and known from the tanners for quite two thousand years (1) by different civilization (Mesopotamian, precolombian...) and till the XIX century mainly into the form of raw, untreated material like bark. Than chemical companies start to increase he yield of tan content by proceeding into extraction with autoclave and spraydrying leading to extract such as Chestnut or Mimosa having m...

The present investigation was carried out, to evaluate the chemicals present in seismonastic plants. Specially Biophytum sensitivum of oxalidaceae family. Mimosa pudica, Neptunia triquetra of Mimosae family. All these three plants are traditionally used in medicine for different kinds of ailments. After critical study it was found that these plants show variation in presence of some kinds of ch...

In plants, chemical and mechanical traits are involved in the defense against environmental stressors. case of Mimosa touch-sensitive responses through leaf-closure provide a unique form defense. While past research has shown that impacts stressors such as competition or short-term drought may cause defenses plants to increase decrease, it is unknown how interaction these influence efficiency r...

The objective of this work was to characterize nutritional parameters bee pollens from plant species occurring in a semiarid region, Picos, state Piaui, Brazil. Bee pollen samples were collected the experimental apiary Study Group on Bees Semiarid Region Piaui (GEASPI/UFPI) and subjected melissopalynological analysis determine their botanical origins, bromatological (crude protein, lipids, fibe...

Members of the genus Burkholderia (β-proteobacteria) have only recently been shown to be able to establish a nitrogen-fixing symbiosis with several legumes, which is why they are also referred to as β-rhizobia. Therefore, very little is known about the competitiveness of these species to nodulate different legume host plants. In this study, we tested the competitiveness of several Burkholderia ...

For the most part, economic research in Latin America has had a ‘macro’ orientation (e.g., economic growth, monetary and fiscal policy, hyperinflation crisis). This is perfectly understandable because of the macro instability that has affected the entire region for decades and that still remains in many places. However, the composition of research is gradually changing as more attention is paid...

Horizontal gene transfer (HGT) is an important mode of adaptation and diversification of prokaryotes and eukaryotes and a major event underlying the emergence of bacterial pathogens and mutualists. Yet it remains unclear how complex phenotypic traits such as the ability to fix nitrogen with legumes have successfully spread over large phylogenetic distances. Here we show, using experimental evol...

AIM OF THE STUDY Evaluations of the anti-snake venom efficacy of Mimosa pudica tannin isolate (MPT) obtained from root of the plant. MATERIALS AND METHOD MPT was investigated in vitro and in vivo for its efficacy against the venom of Naja kaouthia snake. RESULTS In vitro: (1) mice injected i.p. with MPT pre-incubated with Naja kaouthia venom at concentrations as low as 0.625 mg/ml showed 10...

The accumulated litter is one of the bioindicators programs for recovery degraded areas due to its importance in biogeochemical cycle forest ecosystems. Thus, this study aimed evaluate stock and water retention capacity six-year-old homogeneous plantations Mimosa tenuiflora different spacings (2 m x 2 3 m) municipality Macaíba, RN. In each planting, 10 samples layer on soil were collected throu...
