GC-MS Analysis of Volatile Components from Fresh Leaf-buds of Vaccinium dunalianum var.dunalianum

The volatile components from the fresh leaf buds of Vaccinium dunalianum var. dunalianum were extracted by steam distillation extraction, and analyzed by gas chromatography and mass spectrometry (GC MS). 27 components out of the 44 volatiles extracted were identified, which included 8 alcohols, 5 alkanes, 5 esters, 3 olefins, 2 acids, 2 aldehydes, 1 ketone, and 1 pyran. Among which the content of decahydro dimethylnaphthalene was the highest, reaching 47035%, and the other major compounds were linalool (3185%), 3,7 dimethyl 1,5,7 octatrien 3 ol (1398%), and benzene acetaldehyde (1034%).
