Chemische Eigenschaften
clear liquid
Occurrence
Reported found in papaya fruit, tea tree oil, tangerine, citrus, mandarins, Finocchoi fennel oil, papaya fruit,
citrus peel oils, etc.
Verwenden
γ-Terpinene can be used as:
- Hydrogen precursor in the catalytic transfer hydrogenation of silyl enol ethers.
- A reference compound in the kinetic study of ozonolysis of (E)-β-farnesene.
- A hydrogen atom donor in the Cr-catalyzed radical cyclization of halo acetals.
synthetische
From geranyl pyrophosphate by migration of a positive-charge, hydrid shift from the isopropyl side chain into the
cyclohexenoid ring; from the essential oil of Lantana camara; also from p-cymene by the action of sodium and alcohol in liquid
ammonia.
Allgemeine Beschreibung
γ-Terpinene, volatile essential oil derived from
Melaleuca alternifolia, shows antimicrobial properties against various human pathogens. It is also extracted from
Lippia multiflora. The antioxidant, anti-inflammatory and anti-proliferative activities of γ-terpinene is studied.
Pharmakologie
Combinations of terpenes, such as terpinene, with nonionic surfactants and stabilizers
have been patented for use as gallstone solvents. Artificial or human cholesterol calculi placed
in terpinene with or without human bile at 37°C were dissolved within 1-2 hr (Hisamitsu Pharmaceutical
Co., Inc., 1973).
Sicherheitsprofil
Moderately toxic by
ingestion. A skin irritant. When heated to
decomposition it emits acrid smoke and
irritating fumes.
