Fennel Oil Usage And Synthesis
| Chemical Properties | Fennel oil is obtained by steam distillation of the aerial parts of Foeniculumvulgare Mill. ssp. vulgare var. vulgare (bitter fennel). It is a colorless to paleyellow liquid with a camphoraceous, sweet–spicy odor and a slightly bittersweetcamphoraceous taste, d2020 0.944–0.973; n20D 1.514–1.538; α20D +11 ° to +29 °.The main constituents are monoterpene hydrocarbons such as ??-phellandrene(0–8.5%) and limonene (1–6%), fenchone (10–25%), estragole (1–6%), and(E)-anethole (50–78%). With increasing maturity of the fruits, the contentof monoterpenes decreases. The ripe fruits yield an oil with 50–70% anethole and5–25% fenchone. In contrast, the oil of the ripe fruits of sweet fennel (F. vulgareMill. ssp. vulgare var. dulce) contains less than 5% fenchone and more than 75% anethole.
Fennel oil is produced mainly in Hungary, Tasmania, North Africa, and Indiain a quantity of few 10 t/yr. In total. It is used in flavoring oral care products andalcoholic beverages (anise liqueurs). |
| Chemical Properties | The oil is obtained by steam distillation of the seeds Fennel sweet oil has a characteristic anise odor. |
| Chemical Properties | The oil is obtained by steam distillation of the dried, comminuted seeds in varying yields, usually from 2 5 to 6 5%, depending on the plant origin It has an aromatic, spicy odor and an initially slightly bitter, camphoraceous, then sweet, favor. |
| Physical properties | It is a colorless to pale-yellow liquid. |
| Physical properties | It is a yellowish-green liquid. |
