Plant roots, leaves, barks, seeds berries, or flowers can be used to promote health and treat diseases and also have compounds that provide information about the best quality of raw materials. A medicinal plant native to the Amazonia region (Brazil) was investigated in this work. For this purpose, a new analytical approach was developed by capillary zone electrophoresis (CZE) with UV detection for the separation of 14 phenolic compounds extracted from the plant extracts. The method enabled simultaneous determination of 3-acetylcoumarin, resveratrol, 6-hydroxycoumarin, catechin, rutin, ferulic acid, quercitrin, kaempferol, fisetin, myricetin, quercetin, caffeic acid, gallic acid, and 4-hydroxycinnamic acid using borate buffer (20 mM, pH 9.2) containing 15% methanol (v/v) as working electrolyte, separation potential of ?20 kV, separation temperature of 25°C and hydrodynamic injection by gravity (20 cm for 60 s). The developed method was validated, obtaining repeatability and inter-day precision values lower than 7% and 6%, respectively. Recovery was performed and ranged from 84% to 118%. The method permitted the quantification of catechin and rutin in Connarus perrottetii var. angustifolius aqueous infusions, ethanolic extracts, and butanolic extracts (both obtained after maceration). The radical scavenging activity of the extracts toward free radicals is also described. |

The molecular mechanisms of plant recognition, colonization, and nutrient exchange between diazotrophic endophytes and plants are scarcely known. Herbaspirillum seropedicae is an endophytic bacterium capable of colonizing intercellular spaces of grasses such as rice and sugar cane. The genome of H. seropedicae strain SmR1 was sequenced and annotated by The Parana´ State Genome Programme?GENOPAR. The genome is composed of a circular chromosome of 5,513,887 bp and contains a total of 4,804 genes. The genome sequence revealed that H. seropedicae is a highly versatile microorganism with capacity to metabolize a wide range of carbon and nitrogen sources and with possession of four distinct terminal oxidases. The genome contains a multitude of protein secretion systems, including type I, type II, type III, type V, and type VI secretion systems, and type IV pili, suggesting a high potential to interact with host plants. H. seropedicae is able to synthesize indole acetic acid as reflected by the four IAA biosynthetic pathways present. A gene coding for ACC deaminase, which may be involved in modulating the associated plant ethylene-signaling pathway, is also present. Genes for hemagglutinins/ hemolysins/adhesins were found and may play a role in plant cell surface adhesion. These features may endow H. seropedicae with the ability to establish an endophytic life-style in a large number of plant species. |
