Abstract: The extractives from the medicinal plant Helichrysum patulum were isolated in the crude form and compounds comprised thereof identified using standard techniques.The types of compounds isolated included : glucosides e.g.arbutin and sitosterol glycoside, monoterpenes e.g.pinene, terpineol and limonene, sesquiterpenes e.g.viridiflorol, βcaryophyllene, (-)-alloaromadendrene, muurolol, γ-gurjunene and long chain carboxylic acids e.g.hexadecanoic acid and tetradecanoic acid.Soxhlet extraction , flash chromatography , thin layer chromatography and column chromatography techniques were central to the isolation of the compounds.Structural elucidation included the use of 1D and 2D NMR spectroscopy such as 1 H, 13 C, COSY, HMQC and HMBC spectroscopy.3.5.1 Discussion 3.5.2General discussion on essential oils 4.
