Angelica Root Absolute

#### Angelica Root Absolute. **Angelica Root Absolute **is produced by a two-step extraction of angelica roots. For details of botanical origin etc., see **Angelica Root Oil. **The comminuted roots are first extracted with petroleum ether or benzene, and the solvent is completely recovered in vacuum. The residue (= the concrète extract) is subsequently extracted with ethyl alcohol. The alcoholic extract is chilled, filtered and evaporated under vacuum. After recovery of the alcohol, the **Angelica**** ****Root Absolute **is left as a viscous, yellow-brownish liquid. According to the method of extraction and depending particularly upon the strength of alcohol used, the absolute contains little or no **Phellandrene. **This fact is distinctly reflected in the odor-flavor characteristics of **Angelica Root Absolute.** Its odor is intensely musky-woody, heavy, sweet, somewhat spicy, with a resemblance to Pimpinella root. The richness in odor body has some similarity to that of ambrette seed absolute, but the earthy, root-like notes of the angelica root absolute recall the odor of a drugstore. There is hardly any distinct topnote or pepperiness at all. (Note the difference from the odor of angelica root oil). **Angelica Root Absolute **is particularly well qualified for flavors where the poorly soluble and unstable monoterpene **Phellandrene,**** **would be a drawback. **The**** ****Minimum**** ****Perceptible**** **of the absolute is about 0.005 to 0.010 mg%, placing this material among the most powerful flavor materials of natural origin. Angelica root absolute can be used in perfumery for its unusual tenacity and peculiar animal note, combined with a rich body. The absolute does not impart the typical topnote effects which can be obtained with the essential oil from the root. **Angelica Root Absolute **is produced almost exclusively in France, and only on a very limited scale; locally grown or imported root material is extracted in the Grasse region. The absolute is considerably more expensive than the essential oil, although the comparatively good yield by extraction should make possible a lower cost of the absolute in case of increased demand.
