Investigation of Essential Oil Constituents Isolated from Trichodesma africanum (L.) Grow Wild in Egypt

摘要

Chemical composition of Egyptian Trichodesma africanum (L) essential oil has a few studies, so, this present investigation was carried out to study the essential oil content and chemical composition of Trichodesma africanum (L) plants as a new natural source of essential oil. Plant material was collected from wild plant populations of Trichodesma africanum (L) (family Boraginaceae) growing in sandy soils on Gebel Elba region, Egypt. The essential oils obtained by water distillation from aerial parts of Trichodesma africanum (L) yielded 0.2%. Seventeen constituents representing 86% of the Egyptian Trichodesma africanum (L) essential oil were identified. The major components of Egyptian Trichodesma africanum (L) essential are caryophyllene oxide (15.6%), y-eudesmol (13.7%), a-muurolene (10.5%),elemol (7.0%), carvone (6.8%) and β-caryophyllene (6.6%). Minor component is a-pinene (0.1%). sesquiterpene hydrocarbons reached its highest concentrations (44.6%).
