Gum rockrose utilization

Utilization of biomass from the Gum Rockrose (Cistus Ladanifer)

Gum Rockrose is a Mediterranean shrub, associated with degraded forest areas, which has traditionally been used for the extraction of labdanum.

The gum rockrose (Cistus Ladanifer) is a shrub that grows in the western half of the Iberian Peninsula (acid domain), in degraded Mediterranean forest or mountain landscapes, usually as a consequence of fires, and therefore usually rural areas of low agricultural value and associated with depopulated areas and high risk of fire. However, this plant has great potential as a source of high added value organic compounds, mainly terpenes.

It stands out among them the pinenes, which are the base of pine turpentine and with a growing interest in the context of the green economy in which it is necessary to look for viable alternatives to oil derivatives, but mainly sesquiterpenols, such as viridiflorol, from use in the cosmetic and perfumery industry.

The current activities to obtain these compounds in the form of essential oils (distillation) or labdanum (extraction), generally use artisan techniques that do not also allow optimal use of the biomass fractions of Jara Pringosa

For this reason, Reanga Química is currently preparing, in collaboration with other companies, a research project of a technique that optimizes both the fractionation of the gum rockrose lignocellulosic biomass and the extraction of organic compounds of a terpenic nature and high added value present in the same.

This project also includes other aspects of forest engineering that includes silvicultural management models of the masses of jaral, evaluation of mechanized harvesting, etc. We are also looking for a comparative study of the presence of these compounds in specimens of gum rockrose from different parts of the Extremadura region.
