 Much-branching shrub with straight spines, up to 3m high, native to West Indies, Central America, naturalized in tropics (Asia, Africa, Australia); cultivated in USA, Egypt, North Africa; stipules of some or all the leaves persistent and spinescent; leaves bipinnate, the pinnae 2-6 pairs; leaflets mostly 10-25 pairs, linear, glabrous; flowers deep yellow, very fragrant, in heads 2-3 in the older axils; pod cylindric, scarcely dehiscent, filled with a pith wich seperates the seeds from each other (grown in early times in botanical gardens of Rome, the Farnesian Garden).  Much-branching shrub with straight spines, up to 3m high, native to West Indies, Central America, naturalized in tropics (Asia, Africa, Australia); cultivated in USA, Egypt, North Africa; stipules of some or all the leaves persistent and spinescent; leaves bipinnate, the pinnae 2-6 pairs; leaflets mostly 10-25 pairs, linear, glabrous; flowers deep yellow, very fragrant, in heads 2-3 in the older axils; pod cylindric, scarcely dehiscent, filled with a pith wich seperates the seeds from each other (grown in early times in botanical gardens of Rome, the Farnesian Garden).

 +"Known as Cassier du Levant in the South of France... The scent profile of cassie absolute is warm, honeyed, iris-powdery and quite balsamic with a hint of cinnamon, berry and aniseed, combined with a herbaceous floral effect. Its aroma therapeutical properties include help in dealing with stress and depression." \\

 +The absolute oil of cassie (Acacia farnesiana Willd.) has been fractionated by distillation and investigated by using several combined chromatographic techniques. The group with the most volatile compounds (A) contained benzoid structures like methyl salicylate, benzyl alcohol, benzaldehyde, benzyl acetate, methyl benzoate and the C6-C10 n-aldehydes. A further group (B) contained benzoid compounds like methyl 2-methoxybenzoate, methyl 2,6-dihydroxy benzoate, methyl 2-hydroxy-6-methoxy benzoate, anisaldehyde, anisyl alcohol, anisyl acetate, eugenol, veratraldehyde, and carotenoid cleavage products like alpha-ionone, beta-ionone, dihydro-beta-ionone. (Z)-3-methyl-3-decen-1-ol has been found as a new special component of the absolute. Group (C) contained a complex mixture of compounds with characteristic cassie odor. Main components were linoleic and linolenic acid with their esters. Further substances were eg. heptadecane, nonadecane, (Z)-3-methyl-3-decenoic acid, methyl vanillate, methyl anisate, methyl veratrate, dihydroactinidiolide, (E)-3-methyl-4-decenoic acid, methyl 2,6-dimethoxybenzoate, methyl 2-hydroxy-3-methoxybenzoate, methyl myristate and benzyl benzoate. \\ 
 +The unusual C11 compounds play a prominent role in the characteristic fragrance of cassie oil. \\

 +From A.farnesiana blossoms, 220ppm of volatiles could be extracted with vacuum distillation/solvent extraction. Major components of the extract were methyl salicylate (42.9%), p-anisaldehyde (15.6%), geraniol (8.8%), geranial (2.5%), geranyl acetate (3.2%), nonadecane (2.8%), benzaldehyde (3.0%), 3-methyl-3-decen-1-ol (1.7%), and methyl 2,6-dihydroxybenzoate (0.9%). Further compounds found were eg. naphtalene, myrcene, benzyl acohol, benzyl acetate, limonene, ocimene, linalool and linalool oxides, (E,Z)-2,6-nonadienal, (E)-2-nonenal, (Z)-3-nonen-1-ol, β-cyclocitral, ethyl salicylate, benzyl 2-methylpropionate, 3-methyldec-4-en-1-ol, citronellyl acetate, neryl acetate, methyl p-anisate, p-anisyl acetate, α-ionone, β-ionone, and methyl 6-methoxysalicylate. \\

 +The flower absolute of A.farnesiana has been found rich in cleavage compounds of linoleic acid (adding characteristic fresh notes) like (E)-2-nonenal (0.4%), (E,Z)-2,6-nonadienol (0.5%), (Z)-3-nonen-1-ol (0.1%), (E)-2-nonen-1-ol (0.05%), (Z,Z)-3,6-nonadien-1-ol (0.3%), (E,Z)-2,6-nonadien-1-ol (0.3%). \\

-"The absolute oil of cassie (Acacia farnesiana Willd.) has been thoroughly investigated by using several combined chromatographic techniques. Among the 38 new constituents which were thus identified in this oil, four deserve a particular mention, namely, the cis-3-methyldec-3-en-1-ol (I), the related acid III, the trans-3-methyl-dec-4-enoic acid (IV), and the homoterpene lactone dihydroactinidiolide (II). With the exception of the last one, these unusual C11 compounds play a prominent role in the characteristic fragrance of cassie oil." \\
