Genetic resources of Tunisian Artemisia arborescens L. (Asteraceae), pattern of volatile metabolites concentration and bioactivity and implication for conservation
Publication date: December 2019Source: Biochemical Systematics and Ecology, Volume 87Author(s): Leila Riahi, Hnia Chograni, Ahmed Slaheddine Masmoudi, Ameur CherifAbstractArtemisia arborescens L. (Asteraceae) is an endemic and a valuable medicinal and ornamental species in the Mediterranean regions. Despite the interest given to A. arborescens L. as promising medicinal crop, this species is becoming threatened of extinction in Tunisia as a result of the fragmentation of its habitat and the absence of any specific measures for its conservation and valorisation. Based on the last considerations, extent information about thei...
