Abstract

A concrete from Acacia caven (Mol.) Mol. flowers collected in the central region of Argentina, at the end of the spring, was isolated by extraction with light petroleum ether yielding 1.09%. Volatile compounds of the concrete were isolated by steam distillation yielding 0.06% (m L of oil/100 g of extracted flowers). Flower oil was analyzed by GC and GC/MS. The main constituents were: geranyl acetone (2.2 %), β-eudesmol (4.0 %), (E,E)-farnesol (3.1 %), (E,E)-farnesyl acetate (6.2 %), nonadecane (15.4 %), kaurene (6.6%), heneicosane (13.5%), tricosane (7.7%) and pentacosane (6.6%). The variation in group content was: monoterpenes (0.9%), diterpenes (7.5%), linear saturated hydrocarbons (49.9%), linear unsaturated hydrocarbons (1.4%), oxygenated sesquiterpenes (9.0%), and other oxygenated compounds (17.0%).
