Abstract:

Headspace solid phase microextraction combined with gas chromatography–mass spectrometry(HS–SPME–GC–MS)was used to analyze the volatile components in the flowers of Cymbidium goeringii and Cymbidium faberi,which were collected from different locations in Qinling Mountains. The results showed there are more than 40 kinds of volatile components in the flowers of C. goeringii. The main components consist of 3-ethyl-2-methyl-1,3-hexadiene,(E)-2-octenal,2-nonenal and so on. C. goeringii in different habitats have analogous compositions. The aromas in the flowers of C. goeringii only have a few categories,and most of the C. goeringii is without smelling fragrance in flowers. There are more than 50 kinds of volatile components in (E)-3,7,11-trimethyl-1,6,10-dodecatrien-3-olthe flowers of C. faberi. The main components consist of,doconexent,and [1à,2à(Z)]-cyclopentaneacetic acid-3-oxo-2-(2-pentenyl)-methyl ester and so on. Most of the volatile components in the flowers of C. faberi smell fragrant,making C. faberi having richer aromas than C. goeringii in flowers. Thus the compositions of volatile components in C. faberi flowers are more complex and have more aromatic categories than C. goeringii.

Key words: Cymbidium goeringii, Cymbidium faberi, volatile component, aroma, Qinling Mountains
