COMPARISON OF THE VOLATILE COMPOUNDS FROM SEVERAL COMMERCIAL PLUM CULTIVARS

Volatile fractions were prepared from five ripe commercial plum cultivars and one breeding line by continuous vacuum steam distillation-hexane extraction and analyzed by capillary GC and GC-MS. Thirty-six compounds were identified. The eight major compounds for most cultivars were hexenal, butyl acetate, (E)-2-hexenal, butyl butyrate, hexyl acetate, linalool, gamma-decalactone, and gamma-dodecalactone. Minor constituents included eleven esters, two alcohols, four lactones, two terpenes, two saturated hydrocarbons, palmitic acid, three phenyl compounds and nonanal.
