Abstract: Aromatic components in flowers of 7 cultivars of Fressia hybrida were determined using the headspace-solid phase micro-extraction followed by gas chromatography-mass spectrometry for comparison. The results showed that alcohols and olefins were the main aromatics in the flowers. Olefins were found in the largest quantities in Rose Marie flowers, while alcohols,especially,linalool in the flowers from other cultivars. Cluster analysis showed that the genetic makeup of Rose Marie differed from those of White Wing, Jintong, Shuguang, Xiangmei, Ziyu, and Royal Blue.
