Sweet Basil Oil Extraction and Composition

Sweet Basil Oil is typically extracted using Steam Distillation, a common method for obtaining essential oils from herbs.

The main components of Sweet Basil Oil are usually phenylpropanoids such as Methyl Chavicol (Estragole) and Linalool. Depending on the source and variety of basil, other compounds may also be present in varying amounts, including Eugenol, 1,8-Cineole, Limonene, Geraniol, and others. These compounds are the primary constituents that give basil its characteristic aroma. However, the essential oil obtained through steam distillation primarily consists of volatile compounds, which are the main part of what you referred to as "aromatic substances."

Generally, essential oils produced by steam distillation mainly contain volatile components. Other non-volatile components like fats or large complex compounds are typically not extracted by this method.
