摘要

This experiment was conducted to find the optimum time for the extraction of volatile compounds in Rosa hybrid. Qualitative and qualitative variation of volatile compounds according to flowering stages was determined by using gas-chromatography mass spctrometry (GUMS). The eleven volatile compounds were detected in flowers of R. hybrida 'Orange Flash', and a major compound was 3,5-dii-netlioxytoluene. The percentage of volatile compound in flowering stage IV accounted for 77% (3,5-dimethoxytoluene), 7.4% [2,6,10,10-tetramethyl-1-oxa-spiro(4.5)dec-6-ene], 7.1% (dihydro-beta-ionol) and 1.9% (1-hexanol). The thirty volatile compounds were detected in flower of R. hybrida 'Blue Moon', and the major compounds were geraniol, nerol and beta-citronellol. The percentage of volatile compounds in flowering stage IV accounted for 30.1% (geraniol), 17.0% (nerol), 9.9% (beta-citronellol) and 7.2% (germacrene-D). The contents of volatile compounds differed from the flowering stages of R. hybrida, which were the greatest in flowering stage IV. As a result, the flowering stage IV of R. hybrida was recommended as the optimum time to extract volatile compounds for industry.
