CHEMICAL COMPOSITION OF THE ESSENTIAL OIL OF Launaea arboresens from Algerian Sahara

摘要

The genus Launaea(Asteraceae)is represented in the flora of Algeria by nine species including five endemics of north africa [1].Among them,Launaea arboresens(local name "Oum Lbina")is an endemic herbaceous medicinal plant mainly distributed in the southwest of Algeria and southeast of Morocco [2,3].To the best of our knowledge,there are no references about the oil content and chemical composition of Launaea arboresens.Thus,in continuation of our ethnopharmacological,phytochemical,and antimicrobial studies of the Algerian Sahara medicinal plants [4-6],we report here the results of our studies on the composition of L.arboresens oil from Algerian Sahara.
