ALMEIDA, MACIA C.S. DE et al. 7-epi-griffonilide, a new lactone from Bauhinia pentandra: complete 1H and 13C chemical shift assignments. An. Acad. Bras. Ciênc. [online]. 2017, vol.89, n.1, pp.65-71. ISSN 0001-3765.  http://dx.doi.org/10.1590/0001-3765201720150757.

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.
