“…It consists of about 300 species, distributed in most tropical countries, including Africa, Asia and America (Cechinel Filho 2009). Previous phytochemical studies with plants from Bauhinia genus report the presence of lactones, flavonoids, terpenoids, steroids, triterpenes, tannins, quinones and alkaloids Cechinel Filho 2002, Maia Neto et al 2008), while studies from B. pentandra reported the chemical composition of the essential and fatty oils (Duarte-Almeida et al 2004, Almeida et al 2015, as well as the isolation of flavonoids (Salatino et al 1999) and cyanoglucosides (Silva et al 2013). In this paper, we report the isolation and structure elucidation of lactones (1 and 2), phenylacetic derivatives (3a, 3b and 3c) and a mixture of cyanoglucoside (4a) and glucopyranoside (4b).…”
