Analysis of Aroma Components in Flowers of Three Kinds of Camellia by HS-SPME/GC-MS
The aroma components in flowers of three kinds of Camellia (C. japonica Linn., C. oleifera Abel., C. sinensis (L.) O. Kuntze) were analyzed by HS-SPME/GC-MS. Significant differences in aroma components and their relative amounts in the flowers from three kinds of Camellia were observed. Totally 26, 36 and 48 aroma compounds were identified from C. japonica Linn., C. oleifera Abel, and C. sinensis (L.) O. Kuntze, which accounted for 94.53%, 96.43% and 98.76% of the total aroma components, respectively. 1-hexanol, 1-phenyl-ethanone, linalool, trans-anethole, dehydrogeosmin, germacrene D, butylhydroxytoluene and δ-cadinene were identified in flowers from three kinds of Camellia, but their relative contents showed a considerable difference. In addition, unique aroma components in the flowers of each kind of Camellia were also detected. Eugenol and decylacetate were the characteristic compounds in C. japonica Linn.; dihydro-3-methyl-2(3H)-furanone and myrcene were the characteristic compounds in C. oleifera Abel.; 6,10,14-trimethyl-2-pentadecanone and citral were the characteristic compounds in C. sinensis (L.) O. Kuntze.
