化学的特性
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.
天然物の起源

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.
使用
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).
製造方法
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.
一般的な説明
α-Terpinene, a volatile essential oil derived from
Melaleuca alternifolia, shows antimicrobial properties against various human pathogens.
薬理学
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).
安全性プロファイル
Moderately toxic by
ingestion. When heated to decomposition it
emits acrid smoke and irritating fumes.
