 **Fig leaf absolute**
-The leaves of Ficus carica are extracted with solvent to obtain a concrete, which is subsequent treated with alcohol. The residue represents a dark green to brownish green viscous liquid of a sweet, green, herbaceous, somewhat woody odor with a mossy undertone. The first distillation range (30-160°C/0.05 Torr) of this fig leaf absolute is the olfactory relevant part - only 1% (!). Main components of this part are hydrocarbons like caryophyllene, α- and β-farnesene, furthermore linalool, benzyl acetate, (Z)-3-hexenyl tiglate, methyl salicylate, β-ionone, and (Z)-3-hexenyl benzoate. Minor components are (Z)-3-hexenyl butyrate, (Z)-3-hexenyl 2-methylbutyrate, methyl benzoate, linalyl acetate, β-cyclocitral, safranal, α-terpineol, benzyl alcohol, geranyl acetate, phenylethanol, β-damascenone, geranylacetone, jasmone, caryophyllene oxide, and cinnamyl acetate e.g. Further minor but olfactory important constituents were pyridines and pyrazines like 2-isobutyl 4-methylpyridine (tobacco-like, green) , 2-isobutanoyl 4-methylpyridine, 2-isobutenyl 4-methylpyridine (tobacco-like, bitter, fruity-floral), 2-methoxy 3-isopropylpyrazine, 2-methoxy 3-sec.butylylpyrazine, 2-methoxy 3-isobutylpyrazine e.g. \\
