Volatile oils in leaves of Bauhinia (Fabaceae Caesalpinioideae)

Comparative assessment of kaempferitrin from medicinal extracts of Bauhinia forficata Link

“…The volatile oil from the leaves of B. forficata has been characterized [18], and only kaempferol and quercetin O-glycosides have been isolated [2][3][4]. Some attempts have been made to attribute the antidiabetic effects of the leaf extracts to the major flavonoid derivative (kaempferitrin) [19,20].…”

Chemical component and antimicrobial activity of volatile oil of Calycopteris floribunda

“…Concerning the biological activities of essential oil of C. floribunda, some of the sesquiterpenes found in leave oil, such as caryophyllene oxide, showed to have anti-fungal, as well as insecticide and antifeedant activities [15]. Although detected in minor amounts, the terpenes: o-cymene, β-linalool, safranal, β-cyclocitral, α-ionene, cyperene, β-cubebene, β-eudesmene, τ-elemene, τ-himachalene, spathulenol, cedrenol, epiglobulol and myristic acid, were exclusively found in leave oil.…”

7-epi-griffonilide, a new lactone from Bauhinia pentandra: complete 1H and 13C chemical shift assignments

“…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).…”
