Chemical investigation of the lipoidal matter of Glossostemon bruguieri and the acaricidal activity of its unsaponifiable fraction
Acarologia 40 (2), 199-204
Abstract: The unsaponifiable matter (USM) and the total fatty acid methyl ester (FAME) fractions of Glossostemon bruguieri (Desf.) growing in Egypt were determined for seeds, leaves and roots. Qualitative and quantitative variations were found by GLC analysis of the "USM" of the three botanical parts. Analysis of FAME revealed that palmitic, stearic, oleic and linoleic were the main fatty acids in the investigated botanical parts. Moreover, acaricidal activity of the unsaponifiable matter of each organ was performed, from which the leaves was the most toxic to both adult and egg stages of Tetranychus urticae Koch.
