説明
Herbaceous, tall plant that grows in northern Persia (F galbaniflua)
or in southern Persia (F. rubicaulia and F. ceratophylla). F.
galbaniflua is widespread also in Turkey and Lebanon. The plant
yields a resinous exudate, which is the part used, distinguished commercially in two types: Levant galbanum (soft) and Persian
galbanum (hard). The resin has a characteristic, aromatic odor and
a bitter, warm, acrid taste. It contains approximately 15 to 26%
essential oil. Galbanum has a warm, resinous, somewhat spicy and
balsamic odor.
The essential oil is obtained by steam distillation of the dried
resinous gum. It is a pale-yellow to yellow liquid with a balsamic,
somewhat spicy, characteristic odor. Its main constituents include
myrcene, cadinene, d-α-pinene, β-pinene, and sesquiterpene alcohols.
The resinoid once was prepared by hydrocarbon solvent extraction
and subsequent evaporation of the solvent; today a high-boiling,
odorless solvent is added prior to evaporation; this solvent is left
in the finished commercial product. The solvent-free resinoid is a
dark-amber, viscous liquid with a characteristic balsamic odor. It
yields turbid solutions in alcohol.
化學(xué)的特性
Galbanumoil and galbanumresinoid are produced fromthe gum-like exudate
of Ferula gummosa Boiss. (syn. Ferula galbaniflua Boiss. et Buhse) (Apiaceae),
growing inNorthern Iran, and Ferula rubricaulis Boiss., growing in Southern Iran.
The gum is collected from a cut in the upper part of the uncovered roots. The
annual yield of gum is ～50 t.
The oil is produced by steam distillation and is a yellow liquid with a green, slightly spicy odor.

In addition to 75% monoterpene hydrocarbons (α-pinene 5–21%; β-pinene 40–70%; 3-carene 2–16%) and about 10% sesquiterpene hydrocarbons, galbanum
oil contains a fairly large number of terpene and sesquiterpene alcohols
and their acetates. Minor components, with entirely different structures and low odor threshold values, contribute strongly to the characteristic odor.
Galbanum oil is used for creating green top notes in perfume compositions.
Galbanum resinoid is produced by extraction of the gum with a nonpolar
solvent. It is used for the same purposes as the oil and has excellent fixative properties.
