MIMOSA ABSOLUTE MOROCCAN

化学的特性Mimosa absolute is obtained from the blossoms of the mimosa trees Acacia dealbata Link and Acacia mearnsii De Wild. (Mimosaceae), which grow, for example, in the forests of Southern France and in Morocco. The absolute is a yellowish-brown liquid with a slightly green, floral odor and extremely high tenacity. The odor-determining constituents, for example, phenylethyl alcohol or methyl anisate, are contained only in very small concentrations. Annual production is only some few tons. The main part is produced in Morocco and, in small quantities, also in France and India. Mimosa absolute is used mainly in fine fragrances as a floral fixative.

説明Woody plants native to Australia, having pinnate leaves and yellow flower clusters. The plant has become acclimated to the French and Italian Riviera, where it was transplanted in the early 1800s. It is cultivated for ornamental (flowers) and extractive purposes. The flowers are the part used. Mimosa has a delicate, sweet, floral odor. The derivatives are the concrete, which is extracted from flowers in approximately 0.7 to 1.1% yields using petroleum ether, and the absolute, prepared from the concrete in approximately 20 to 25% yields. The concrete is a pale-yellow wax with a fatty, floral, slightly sweet odor, reminiscent of beeswax. The absolute is a syrupy, viscous, amber-colored or yellowish liquid with a scent similar to that of flowers.

天然物の起源Found in the flowers of Acacia decurrens var. dealhata (Fam. Leguminosae) (Guenther, 1952; Naves, 1974).
