Abstract
Unsaponifiable matter (UNS) of lipids from cashew nuts either roasted, unroasted or unroasted in shell was fractionated on a Florisil column. Gas‐liquid chromatography (GLC) of the hydrocarbons showed that squalene was the major component of the 21 peaks detected. There were three homologous hydrocarbon series: normal, iso and/or anteiso and branched chain. GLC of the alcohol fraction silyl derivatives indicated the presence of three homologous series: normal, iso and/or anteiso and multiple branched chain alcohols. Beta and/or gamma tocopherol was found to be the major tocopherol. This component decreased during nut shell removal and roasting. Cycloartenol, amyrin (alpha‐beta) and 24‐methylene cycloartanol were the triterpenoids identified. GLC of the sterol fraction silyl derivatives showed beta‐sitosterol to be the major sterol followed by campesterol.
