Abstract:
Cistus laurifolius is a shrub naturally distributed in the Iberian Peninsula, Morocco, Southern France, and Turkey. It is known for its resistance to extreme continental climates and adaptability to poor and dry soils, particularly in burnt areas. Promising results have been obtained concerning its harvesting, conditioning, and combustion, although considering the high costs involved in forest management of shrub lands, the search of high added value products, like essential oils, is a key factor to achieve economic viability. The objective of this work is to study the annual variation of C. laurifolius essential oil yield, composition, and antibacterial activity. Samples of Cistus laurifolius were collected in central-East Spain each 2 months between October 2019 and August 2020 and were distilled using steam distillation. Low yields of essential oil were obtained, with the highest values in autumn followed by winter. Regarding the composition of the essential oil, it was variable along the year, with higher concentrations of monoterpenes and oxygenated monoterpenes in autumn and winter, and higher concentrations of sesquiterpenes and oxygenated sesquiterpenes in spring and summer. Additionally, the essential oil exhibited bacteriostatic activity against Gram-negative and Gram-positive bacteria, with particular effectiveness against Staphylococcus aureus.
