• 調製方法

  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.

• 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).
