| Popis: | Cymbidium sinense is a traditional orchid in the tropical and subtropical regions of Asia, and it has attracted attention because of its fragrant flowers and graceful leaves. Essential oils were extracted by simultaneous distillation-extraction (SDE) from the flowers of six cultivars. GC-MS analysis revealed fifty compounds, constituting 78.40-97.96% of the total essential oils. The main constituents were farnesyl alcohol (0.66-12.51%), n-tetracosanol-1(1.07-7.77%), dihydro-β-ionone (0.34-13.16%), β-ionone (0.37-20.23%), pentacosan (10.28-17.51%), heptacosane (6.43-11.90%), α-ionene(2.89-9.14%), tricosane (5.30-8.86%), p-cresol (0.96-6.32%), n-hexadecanoic acid (1.81-6.72%) and linoleic acid (0-16.86%). ‘Baizui baimo’ seemed to be the richest cultivar in alcohols (20.28%) and ketones (33.77%). Six cultivars were separated into 3 chemotypes by hierarchical cluster analysis, according to the composition of the corresponding essential oils. The principal component analysis (PCA) also revealed chemica... |
