Abstract:

Essential oils were extracted by steam distillation method from the autumn leaves and stems of Michelia alba DC., respectively. Then the volatile components in the two extracts were analyzed using GC-MS combines with computer search and their relative contents were identified by peak area normalization method. The results showed that there are 63 and 78 compounds in the essential oils from leaves and stems of Michelia alba DC., respectively, whose relative contents in the essential oils are 95.7 % and 97.3 %, respectively. Moreover, the main aroma components in the two kinds of essential oils are almost the same, including linalool, caryophyllene, nerolidol, germacrene D, β-cubebene, (E)-ocimene, α-humulene and eucalyptol.

Key words: Michelia alba DC., essential oil, chemical constituent, GC-MS
