Inner bark extracts of Stryphnodendron adstringens, a leguminous tree species known as Barbatimão, are often incorporated to phytotherapic formulations due to their antimicrobial and healing activities. In this study, extracts from S. adstringens accessions collected in 12 distinct locations were investigated in order to determine the rates of tannins in inner barks and to validate S. adstringens antibacterial and antifungal effectiveness. Yields of tannins were quantified by colorimetric assay following methodology described in the Brazilian Pharmacopoeia and the antimicrobial activity was determined by microdilution technique proposed by the National Committee for Clinical Laboratory Standards using S. adstringens hydroalcoholic and aqueous extracts and semi-purified fractions. Investigated extracts did not present significant antibacterial activity though aqueous extracts exhibited antifungal effect against both Trichophyton rubrum mutant and clinical strains (MIC 156 μg/mL). A positive correlation between tannin concentration and antifungal activity was observed and the accessions collected in Delfinópolis (MG) were considered elite.

Although nowadays there are methods for determining the Minimal Bactericidal Concentration and Minimal Fungicidal Concentration, it is indispensable that?the establishment of innovative methodologies?could be more practical and cheaper. The new methodology Flash microbiocide is an assay in which one aliquot from 96 well plate of Minimal Inhibitory Concentration test is transferred to another plate containing different culture medium. The correspondence with the reference methods described in the National Committee for Clinical Laboratory Standards (NCCLS-CLSI) document M26-A was achieved, denoting the efficiency of this fast and simple method.

Species of the genus Erythrina are frequently used as ornamental plants and in projects to restore degraded areas. Also, extracts from its shoots and stems are popularly used as a herbal medicine with validated activity on the central nervous system. The objective of this study was to evaluate E. mulungu and E. velutina seed germination and seedling development potential aiming commercial scale production of those species. Seeds stored for one or twelve months at 10°C ± 2°C were sown in sand, soil or Plantmax? substrates and evaluated for germination and seedling development. Subsequently, seedlings sprouted in Plantmax? were transferred to polyethylene bags and kept in greenhouse, under direct sunlight for plant development (plant height, stem diameter and root length pivoting) evaluations. Four-month-old plantlets were transplanted to the field and after a period of one year the collar diameter and shoot height (of each plant were measured. Seed germination rates of both species grown in soil and in Plantmax? were significantly high (over 80%). Storing seeds for 1 month did not inhibit germination. However, seeds stored for twelve months had germination reduced by more than a quarter. The development of plants in greenhouse and in the field was satisfactory, indicating the viability of producing E. mulungu and E. velutina on a commercial scale, in order to meet the expanding market demand for herbal medicines.

Plants are a rich source of antibiotics, but screening all the existing plant species for biological activity using current methods can be time and resource consuming. The present study is to investigate whether powdered plant materials would perform as well as plant extracts in the screening of plants with antimicrobial activity. In the new method proposed (STAMP), we compared in vitro antimicrobial activity of powdered plant materials from 12 species against bacteria and fungi. We confirmed these results with their corresponding aqueous (wet) and hydro-alcoholic extracts and one species testing the antimicrobial activity of two isolated compounds. Compared with hydro-alcoholic extracts, screening using the powdered plant materials correctly identified the majority of the species with antimicrobial activity against Candida albicans (sensitivity 91%, specificity 86%), C. parapsilosis (sensitivity 100%, specificity 67%), and Staphylococcus aureus (sensitivity 64%, specificity 86%). For bacteria, the method performed better in a pH of 9.0. The antimicrobial activity of two compounds isolated from one species (maytenin and netzahualcoyone) confirmed the results. In conclusion, the use of powdered plant materials for screening plants with antimicrobial properties is a cheap, widely available, technically easy, time sparing, reproducible, and sensitive method and can significantly shorten the time and money spent during drug development.

Trauma to the peripheral nervous system often results in loss of motor and sensory functions of the affected area of the body,leading to a series of functional impairments(Allodi et al.,2012).Injuries to peripheral nerves initiate a series of complex events,known as Wallerian degeneration,which allows the injured axons to regenerate and reinnervate their targets(Allodi et al.,2012).Damage to a nerve induces multiple alterations,which include:axonal degeneration,breakdown of myelin sheath,Schwann cells(SC)proliferation and conversion to a repair phenotype which express cytokines and chemokines that allow the infiltration and activation of macrophages(Mietto et al.,2015;Jessen and Mirsky,2016).
