Therefore, the present study had as main objective an ethnobotanical survey in the quilombola community Negro do Osso located in the municipality of Pesqueira-Pernambuco. Ethnopharmacological data were collected through a quantitative survey, using a questionnaire with questions asked through interviews with men and women in the community, totaling 43 interviewed. The results obtained were used to calculate the Use Value (VU) of the cited species and the importance of use of a botanical family, in addition to the classification of the main families and species cited. Based on popular names in scientific databases. In view of the results obtained, a total of 26 species of medicinal plants were observed, distributed in 18 botanical families. Fabaceae, Rutaceae and Lamiaceae families received the highest number of citations. The most cited species were Cymbopogon citratus Stapf, Lippia alba (Mill.) N.E. Br., Mentha sp. and Plectanthus ornatus Codd. The plants with the highest VU were Zingiber officinale, Citrus limon (L.) Osbeck and Dusphania ambrosioides. The recording of ethnopharmacological information from the research is important for the conservation of local knowledge acquired over time by the population. Plant resources are important, as at certain times they become the only resources available to treat conditions that afflict the communityItem Diversidade e uso de recursos na etnoveterinária no Nordeste brasileiro(2022-10-05) Silva, Vitória Ramos Nunes da; Silva, Valdeline Atanazio da; http://lattes.cnpq.br/7112874436105706; http://lattes.cnpq.br/2757983452414661The ethnovet is a practice that has been used since the emergence of man, the use of this practice has evolved over time, and, currently, it has been used by producers, farmers, and veterinarians, for the treatment of diseases , mainly in herd animals. This work is a bibliographic review on the resources (vegetable and animal) used in ethnovet Brazil's northeastern. To develop this research , a survey of data from the literature on the subject was carried out, using the following terms as keywords: ethnobotany and semiarid pdf, ethnobotany pdf, ethnobotany and pdf, ethnovet and semiarid pdf, plants and ethnovet and pdf, animals and ethnovet and pdf. After selecting the articles, monographs, theses, and dissertations published between the years 1990 to 2021, data from 37 studies were used in this review. In total, 160 species of plants and 55 species of animals were registered for ethnovet use. The most cited plants were: Aloe vera (L.) Burm.f. e Astronium urundeuva Engl. (12 quotes), Allium sativum L. and Ximenia americana L. (9), Dysphania ambrosioides (L.) Mosyakin & Clemants (8), Lippia alba (Mill.) N.E.Br. ex Britton & P.Wilson (7), Anacardium occidentale L., Aspidosperma pyrifolium Mart. Zucc., Azadirachta indica A.Juss., Cymbopogon citratus (DC.) Stapf, and Sarcomphalus joazeiro (Mart.) Hauenschild (6). The plants species were most cited for use in healing , inflammation, cleaning parturition, chicken gogo and worms. The most cited animals species were: Tupinambis merianae (Duméril & Bibron) (6), Bos Taurus L., Gallus gallus L., Iguana iguana L., Nothura maculosa cearensis (Naumburg), Ovis aries L., Sus scrofa domesticus L. and Phrynops geoffroanus (Schweigger) (5), Crotalus durissus L. (4) . The animals were used in the treatment of wounds, snakebites, and caltrops. were also cited for worm, boil, tumor, scabies, weakness, poisoning, changing feathers, circulation, wound healing, respiratory disease in birds, eye problems, rheumatism, inflammation, dermatological diseases, and obstetric disorders. It is extremely important that further research be carried out on the subject, so that there is more clarification on the use of these resourcesItem Fungos endofíticos em Bauhinia cheilantha (Bong.) Steud. Leguminosae, no Semiárido pernambucano(2019) Leite, Isnaelia Gonçalves; Costa, Cynthia Maria Carneiro; http://lattes.cnpq.br/9859547718446795; http://lattes.cnpq.br/7234066240200376Endophytic fungi are microorganisms that are present in plants and can colonize inter or intracellular various organs, establishing a mutualist relationship with the host. They can be associated with different plant species, including medicinal ones, producing secondary metabolites of biotechnological interest such as antibiotics. Therefore, the objective of this work was to isolate and taxonomically identify the endophytic fungi present in leaves of Bauhinia cheilantha (cowpaw, mororó) collected in Pernambuco semiarid, as well as to evaluate compound with antimicrobial potential. After random leaf collection and disinfection, 140 fragments were removed to isolate the endophytes in 20 Petri dishes containing Sabouraud Agar medium. Of these, 10 plates were kept at room temperature and 10 were stored in a greenhouse at 30 ° C for five days. Subsequently, isolation peaks were performed in pure culture for seven days. Thirty isolates of endophytic fungi were obtained, of which 17 were submitted to the antimicrobial activity test in Müeller Hinton agar solid medium against potentially pathogenic bacteria. No antimicrobial activity was observed under the tested conditions, however, five genera were identified: Alternaria sp., Bipolaris sp., Colletotrichum sp., Nigrospora sp. and Drecheslera sp., which constitute the first report, so far, endophytic fungi present in B. cheilantha for Pernambuco semiarid.Item Prospecção química e avaliação da atividade antimicrobiana do extrato etanólico das folhas de Schinopsis brasiliensis Engl.(2019) Pereira, Paulo Sérgio da Silva; Souza, Carlos André de; http://lattes.cnpq.br/2774801228288889; http://lattes.cnpq.br/7936364947867276The discovery of antibiotics was a milestone for protection against serious diseases, but with the indiscriminate use of these drugs there were mutations in some microorganisms, which developed some resistance to some known drugs, due to this it was necessary to search for biomolecules from some organisms such as plants, that have important molecular diversity that can contribute to the resolution of this problem, becoming crucial for the development of new drugs. The objective of this work was to analyze some chemical constituents of Schinopsis brasiliensis Engl. (Baraúna), found in the Mata da Pimenteira State Park located in the municipality of Serra Talhada Pernambuco, verifying its antimicrobial potential. For this purpose, some methodologies were used in the literature to perform qualitative phytochemical tests, quantification of total polyphenols, high performance liquid chromatography and multipole agar test to verify and quantify the antimicrobial capacity of the crude ethanolic extract (EEB) of Baraúna, gallic acid , antibiotic (amoxicillin), and a mixture of antibiotic and EEB from barauna. The following phytochemical qualitative tests were identified: tannins, phenols, flavonols, flavonones, flavonoids, flavones, xanthones and alkaloids. 571 μg / mL of total polyphenols were obtained, the presence of gallic acid and possible identification of vanillin and caffeic acid were revealed in HPLC. Microbiological tests of BSE of barauna and amoxicillin in a mixture showed minimal inhibition concentration against all icroorganisms tested as: Klebsiella pneumoniae (1600 μg / mL), Bacillus subtillis (800 μg / mL), Samonella sp. and Escherichia coli (1600 μg / ml). It is possible to conclude the presence of gallic acid as a major component in addition to other classes of secondary metabolites. It was possible to prove that the best synergistic activity (extract + antibiotic) was for Bacillus subtillis.
