Article abstract of DOI:10.1016/0031-9422(95)00398-Q

In addition to lotaustralin and linamarin, a novel cyanogenic glycoside, 2-((6-O-(β-D-apiofuranosyl)-β-D-glucopyranosyl)oxy)-2-methylbutanenitrile, two novel non-cyanogenic glycosides, (2S)-((6-O-(β-D-apiofuranosyl)-β-D-glucopyranosyl)oxy)butane and 2-((6-O-(β-D-apiofuranosyl)-β-D-glucopyranosyl)oxy)propane, and a simple non-cyanogenic glycoside, ethyl β-D-glucopyranoside, were isolated from an ethanolic extract of the fresh root cortex of manihot esculenta.From a methanolic extract of the fresh leaves of this species lotaustralin and linamarin, and two flavonoid glycosides, kaempferol-3-O-rutinoside and quercetin-3-O-rutinoside were isolated. - Keywords: Manihot esculenta; Euphorbiaceae; cassava; roots; leaves; cyanogenic glycosides; non-cyanogenic glycosides; flavonoids.
