alpha-Terpinene Chemical Properties,Uses,Production
Chemical Properties
alpha-Terpinene is a clear colorless to light yellow liquid with a woody, terpene, lemon odor with a lemony flavor, becoming bitter at high levels. It dissolves in ethanol and most non-volatile oils but does not dissolve in water. It is found naturally in oils such as cardamom, sweet oregano, and coriander seed oil.
Occurrence
Reported found in roots, stems, leaves and flowers of Echinacea species. Also reported found in in tea tree oil, papaya fruit, grapefruit, lemon, lime, mandarin, oranage, spearmint, citrus peel oils, cranberry, currants, guava, grapes, raspberry, peach, carrot, celery, cinnamon, clove, cumin seed, ginger, peppermint and corn mint oils, other mentha oils, nutmeg, pepper, mace, parsley, thymus, rum, tea, filberts, pecans, soybeans, passion fruit, beans, sweet marjoram, starfruit, mango, cardamom, coriander seed, origanum, prickly pear, litchi, calamus, dill herb, lovage seed and leaf, juniper berries, laurel, fennel, rosemary, buchu oil, tur meric, sage, nectarines and many other sources.
Uses
α-Terpinene is suitable for use in a study to evaluate the antimycotic properties of Melaleuca alternifolia essential oil (tea tree oil, TTO). 1 It is suitable for use to investigate the in vitro antibacterial activity of the essential oils extracted from the fruits of Coriandrum sativum L. and Foeniculum vulgare Miller var. vulgare (Miller).
Preparation
May be obtained by isolation from the terpene fraction of sweet orange oil or orange terpenes (8 to 10% of the total monoterpenes); by isolation from fractions of American turpentine oil; from 1-methyl-4-isopropylcyclohexadien-1,3-one-2; also from terpinene dihydrochloride with aniline.
Production Methods
alpha-Terpinene can be produced
1) by isolation from the Terpene fraction of
sweet Orange oil or "Orange terpenes".
The title material may constitute as much
as 8 to 10% of the total Monoterpenes.
2) by isolation from fractions of American
Turpentine oil.
3) from 1-Methyl-4-iso-propylcyclohexadien-1,3-one-2.
4) from Terpinene dihydrochloride with
Aniline.
General Description
α-Terpinene, a volatile essential oil derived from Melaleuca alternifolia, shows antimicrobial properties against various human pathogens.
Pharmacology
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).
Safety Profile
Moderately toxic by ingestion. When heated to decomposition it emits acrid smoke and irritating fumes.
