Himatanthus drasticus Leaves: Chemical Characterization and Evaluation of Their Antimicrobial, Antibiofilm, Antiproliferative Activities

Abstract: Plant-derived products have played a fundamental role in the development of new therapeutic agents. This study aimed to analyze antimicrobial, antibiofilm, cytotoxicity and antiproliferative potentials of the extract and fractions from leaves of Himatanthus drasticus, a plant from the Apocynaceae family. After harvesting, H. drasticus leaves were macerated and a hydroalcoholic extract (HDHE) and fractions were prepared. Antimicrobial tests, such as agar-diffusion, Minimum Inhibitory Concentration (MIC) and Min… Show more

“…After this, 10 μL of each bacterial suspension were added to respective wells and the plates were incubated at 37 °C for 24 h. Then, the microbial growth was measured by the resazurin sodium oxide-reduction indicator (30 µL of 0.03% aqueous solution; Sigma-Aldrich, St. Louis, MO, USA). After 40 min of incubation, changes in color from blue to pink were classified as microbial growth [61]. The MIC was defined as the lowest concentration capable of inhibiting bacterial growth.…”

“…Essas e outras indicações são justificadas uma vez que a espécie apresenta resultados de interesse para a pesquisa científica. Isso deve-se ao fato da H. drasticus apresentar efeitos moduladores de algumas atividades farmacológicas, como: anti-inflamatório, antinociceptivo (Almeida et al, 2019;Matos et al, 2013;Lucetti et al, 2010), assim como já descrito o potencial gastroprotetor (Pinheiro et al, 2013;Leite et al, 2009;Colares et al, 2013), antimicrobiano (Nascimento et al, 2018;Figueiredo et al, 2017), antitumoral (Santos et al, 2018;Mousinho et al, 2011), antidiabético (Morais et al, 2020), cicatrizante e inseticida (Morais et al, 2021). Dados como esses, contribuem para compreensão pelo qual a janaguba tem sido bem relatada na literatura.…”

“…No que corresponde às estruturas e formas de utilização da espécie para fins medicinais, os galhos e folhas são relatados nos artigos como partes utilizadas na preparação de extratos (Figueiredo et al, 2017;Sousa et al, 2010). Contudo, houve maior prevalência pelo uso do látex obtido do tronco da planta, verifica-se ao fato da disponibilidade anual e maior representação dos princípios bioativos nesta parte e produto da planta (Almeida et al, 2019;Colares et al, 2013;França et al, 2011;Leite et al, 2009;Lucetti et al, 2010;Matos et al, 2013;Morais et al, 2020;Moura et al, 2020;Pinheiro et al, 2013;Nascimento et al, 2018).…”
