Beschreibung
ι-Limonene has a pleasant, lemon-like odor free from camphora ceous and turpentine-like notes. The most important and wide spread terpene; it is known in the d- and ι- optically active forms and in the optically inactive dl-form (known as dipentene); it has been reported found in more than 300 essential oils in amounts ranging from 90 - 95% (lemon, orange, mandarin) to as low as 1% (palmarosa);1 the most widespread form is the d-limonene, followed by the racemic form, and then ι-limonene.
Chemische Eigenschaften
colourless liquid with lemon odour
Chemische Eigenschaften
d-, l- or dl-Limonene has a pleasant, lemon-like odor free from camphoraceous and turpentine-like notes. Limonene is the most important and widespread terpene; it is known in the d- and l- optically active forms and in the optically inactive dl-form (known as dipentene).
Occurrence
It has been reported found in more than 300 essential oils in amounts ranging from 90 to 95% (lemon, orange, mandarin) to as low as 1% (palmarosa); the most widespread form is the d-limonene, followed by the racemic form and then l-limo nene. Also reported found in ginger, nutmeg, pepper, mace, hop oil, coriander seed, calamus, dill herb, caraway seed and rosemary.
Verwenden
(S)-(-)-Limonene is used to inhibit the proliferation of colon cancer cells. It is also used in artificial essential oils in order to produce (+)-carvone. It is an active component of turpentine. Further, it is used in flavorings, fragrances, and cosmetics. It finds application as a solvent and wetting agent. In addition to this it is used to produce resins.
synthetische
d-Limonene may be obtained by steam distillation of citrus peels and pulp resulting from the production of juice and cold pressed oils, or from deterpenation of citrus oils; it is sometimes redistilled.
Definition
ChEBI: An optically active form of limonene having (4S)-configuration.
Aroma threshold values
Detection: 4 to 229 ppb
Taste threshold values
Taste characteristics at 30 ppm: sweet, orange, citrus and terpy.
Allgemeine Beschreibung
(S)-(-)-Limonene, a monoterpenoid compound, is mostly used in perfumery and in flavoring. On irradiation, it undergoes radiolysis, which leads to a reduction in the optical purity. (S)-(-)-Limonene also shows potent antimicrobial activity.
Flammability and Explosibility
Flammable
Kontakt-Allergie
Limonene is a racemic form of dand l-limonene. d-Limonene is contained in Citrus species such as citrus, orange, mandarin, and bergamot. l-Limonene is contained in Pinus pinea.
Sicherheitsprofil
A skin irritant. When heated to decomposition it emits acrid smoke and irritating fumes.
