Influence of Variety and Location of Growth on Resulting Bramble Dried Leaf Volatiles

Abstract

Leaves from named cultivars of red raspberry (Rubus idaeus) and black raspberry (R. occidentalis) from plants grown both in the field and in a greenhouse environment were harvested, air dried and extracted in a Likens-Nickerson apparatus. The resulting volatiles were analyzed by GC/MS. With red raspberry, 20 peaks were noted for the field grown sample while only 10 peaks were observed with the greenhouse sample. In both red raspberry samples, the major volatile components were 1-octene-3-ol, geraniol and linalool. With field grown red raspberry, decanal was also a major component while no decanal was detected in the greenhouse grown sample. With the black raspberry samples, 20 compounds were observed in each with the major volatiles being (Z)-3-hexen-1-ol, l-octene-3-ol and geraniol.
