Contribuição ao conhecimento químico de plantas medicinais do Nordeste: Bauhini...
Almeida, Macia Cleane Soares deThis work describes the phytochemical investigation of the species Bauhinia pentandra (Bong.) D.Dietr. and Bauhinia monandra Kurz, belonging to the Fabaceae family. The chemical composition of the essential oil from the leaves dried and fresh B. pentandra, obtained by hydrodistillation and solid phase microextraction (SPME), was determined by GC/MS. The major constituent of the oil obtained from the hydrodistil...
7-epi-griffonilide, a new lactone from Bauhinia pentandra: complete 1H and 13C ...
Almeida, Macia Cleane Soares de; Souza, Luciana G. S.; Ferreira, Daniele A.; Pinto, Francisco C. L.; Oliveira, Débora R. de; Santiago, Gilvandete M. P.A new lactone, 7-epi-griffonilide (1), and six known compounds, 2, 3a - 3c, 4a and 4b, were isolated from the leaves of Bauhinia pentandra (Fabaceae). The structures elucidation of 1 and 2 were based on detailed 2D NMR techniques and spectral comparison with related compounds, leading to complete assignment of the 1H and 13C NMR spectra.
