| Abstract | Executive Summary. Gorse (Ulex europaeus) is a European woody evergreen shrub which has become invasive and endemic to the Pacific coast of the United States. This paper is an investigation into potential uses of gorse. The above ground portions of gorse had 50.7% green vegetation, 11.3% flower/fragments and 38% branches/stems. Oil extractions (AOCS Method 5-04) resulted in a mean oil content of 1.33±0.01% in flowery parts of the plant, and 1.35±0.06% in the leafy portions. Extract from steam distillation (100°C) was 2.6% (w/w) of the initial dry weight. Direct distillation resulted in lower amount of volatile extracts at 60°C (2.25% w/w) as compared to 80°C (3.79% w/w). Ethanol extraction resulted in higher amount of extract (2.44%, w/w, dry basis) as compared to hexane extracted (1.22% w/w, dry basis) initial dry matter. Spectrophotometric analysis of ethanol and hexane extracts of gorse had major absorption peaks at wavelengths of 473 nm and 662 nm. Ethanol yields were estimated as 30.2±5.8 gal//ton of gorse. These yields have a potential of 30-40% increase when C5 sugar fermenting microorganisms are used in addition to yeast that can consume only C6 sugars. |
