I.R.S. Melo,A.M.R. Teixeira,D.M. Sena Junior,Hélcio Silva dos Santos,Maria Rose Jane R. Albuquerque,Paulo Nogueira Bandeira,A. S. Rodrigues,Raimundo Braz-Filho,G.O.M. Gusmão,João H. da Silva,J.L.B. Faria,Ricardo Ferreira Bento +11 more
TL;DR: In this article, the vibrational properties of Acetyl aleutitolic acid (AAA) have been characterized by NMR spectroscopy, and the Fourier-Transform Infrared with Attenuated Total Reflectance (FITR) and Fourier Transform Raman (FTR) spectra were obtained at 300 k in the regions 600 cm −1 to 4000 k and 40 k to 40 k for IR and Raman, respectively.
Journal ArticleDOI
Further lipophilic flavonols in Vellozia graminifolia (Velloziaceae) by high temperature gas chromatography: quick detection of new compounds.
Alexsandro Branco,Alberto dos Santos Pereira,Jari N. Cardoso,Francisco Radler de Aquino Neto,Angelo C. Pinto,Raimundo Braz-Filho +5 more
TL;DR: These methods resulted in the detection, isolation and characterisation of a monoisoprenylated flavonol 3,5,4'-trimethoxy-3'-hydroxy-6,7-(2"-isopropenyldihydrofurano)flavone from the ethyl acetate extract of the whole plant.
Journal ArticleDOI
Trachylobane and kaurane diterpenes from Croton floribundus spreng
Paula Karina S. Uchoa,José Nunes da Silva,Edilberto R. Silveira,Mary Anne Sousa Lima,Raimundo Braz-Filho,Letícia V. Costa-Lotufo,Ana Jérsia Araújo,Manoel Odorico de Moraes,Cláudia Pessoa +8 more
TL;DR: A new trachylobane diterpene ent-trACHyloban-18,19-diol was isolated from root bark of Croton floribundus and submitted to derivatization reactions affording four new compounds, showing moderate effect against three cancer cell lines.
Journal ArticleDOI
Novel Trichloro-and Tetrachloroisoflavone Isolated from Ouratea Semiserrta
TL;DR: In this article, the new 3′,6,8-trichloro-4′,5-dihydroxy-7-methoxyisoflavone (1) and 3'5'', 6'8'-tetrachloro (2) were isolated from the wood of Ouratea semiserrate Mart.
