Tuberose absolute

Chemotypes :

The genus Agave L. includes close to 450 species. Among them, Agave amica (Medik.) Thiede & Govaerts is the tuberose species grown for perfumery purposes.

In addition, there are four varieties of tuberose cultivable. We distinguish simple flowers (containing a single row of petals), semi-double flowers (containing two to three rows of petals), double flowers (containing more than three rows of petals) and various flowers (plants containing all types of flowers). The most used variety for perfumery is the simple flower, because it is the most fragrant.

Extraction process :

In India, the cultivation of the tuberose reaches 12,000 hectares. For an optimal development, the flower needs a rather warm climate, at an 86 °F on average. In addition, the use of nitrogen and phosphorus fertilizers is common for tuberose cultivation. In India, the planting of the tuberose takes place from February to May depending on the regions. Also the plants are spaced by a few tens of centimetres. Often a plantation survives for one to three years.
The flowers are picked by hand from July to November. They are collected in bamboo baskets and taken to the factory. There, the baskets are weighed and the flowers are extracted with volatile solvent in an extraction tank for 30 to 60 minutes. An extraction with hexane gives a concrete, after removing the flowers and evaporating the solvent. The absolute is obtained by diluting this concrete in alcohol after a glazing at 32 °F to precipitate the waxes. The overall extraction yield is between 0.12 and 0.18% for the concrete and 20% for the absolute.
These low yields explain the cost of this raw material. On one hectare of land, about 5 million flowers are picked. The extraction yield is better the first two years of cultivation and deteriorates during the third year.

Uses in perfumery :

Used in women's fragrances for floral, chypre and amber notes.

Stability :

Solubility issues in perfumes
The esters identified in this raw material can form their corresponding acid in stability tests

Other comments :

Many insects and diseases can affect a tuberose plant. For example, mites feed on leaves and stems and several diseases caused by Botyris elliptica among others can cause damage to the leaves of the plant. Insecticides exist to preserve the plants.
