Chemotypes :
The genus Syzygium includes 1200 to 1800 species. Clove is the most cultivated of all these species.
The greatest diversity of species in this botanical genus comes from Malaysia and southwestern Australia. There, many species are very little known and little used.

Extraction process :
The oval clove leaves end in a pointed shape. Their color is pink at first, then turns green when mature.
Clove cultivation in Indonesia covers more than 470,000 hectares (2010). The leaves are manually removed and placed in cloth bags, taken to the factory to crush and dry the leaves, after weighing the bags. After drying, the leaves are sent to the extractor, where their steam distillation allows to recover an essential oil with a yield of about 3.5%, after 8 hours of extraction. The essential oil of clove leaf is recovered at the end of the process in a decanter, separating from the distillation water.
Indonesia produces about 2500 tons of essential oil of clove leaf each year. This essential oil is mainly used to extract natural Eugenol.
In addition, it should be noted that cloves can also be extracted to obtain clove essential oil. It contains about the same level of Eugenol but is much more concentrated in Eugenyl Acetate at the expense of Caryophyllene.
