|Abstract:||Initially, tile seeds of Baccharis dracuuculfilia were collected fhnn populations of 10 cliflereut regions, and the cultivation experiment was carried out in an experimental area of 1,800 m2 by cultivating 100 individuals of each population. The essential oil analyses were peribrined on both GC-FID and CC/MS. which allowed the identification of 14 compounds. The oil yield varied from 0.31% to 0.70% among populations and season. The major oxygenated ses(juiterpenes in the cultivated experiment were (E)-nerohidol (32%) and spathuienol (17%). The mean concentration in tile plant of (E)-nerolidol was five times higher in March (136.53 mg/100 g of plant) than it was in July (25.03 mg/100 g of plant). The mean concentration of spathulenol increased about three fold from July (16.25 mg/l00 g of plant) to April (47.50 mng/100 g of plant). © 2009 Allured Business Media.|
