Intraspecific Variation in the Essential Oils from Drimys brasiliensis Leaves and Stem Barks

The essential oils from leaves and stem barks of Drimys brasiliensis Miers (Winteraceae), collected in July and December 2008, were analyzed by GC/FID and GC/MS. The stem bark oils were composed mainly of monoterpenes (July, 45±3%; December, 92±4%), while the oils from leaves showed the predominance...

Zusammenfassung:The essential oils from leaves and stem barks of Drimys brasiliensis Miers (Winteraceae), collected in July and December 2008, were analyzed by GC/FID and GC/MS. The stem bark oils were composed mainly of monoterpenes (July, 45±3%; December, 92±4%), while the oils from leaves showed the predominance of sesquiterpenes (July, 47±1%; December, 55±1%). The variation in the relative amount of constituents could be associated, at least in part, to several microclimatic parameters such as precipitation, temperature and/or phenological state, which were different for each collection of D. brasiliensis.
