摘要:
The chemical composition of the flower concrete oil and leaf oil ofMichelia albahave both been examined by a combination of GC/MS and retention indices. Approximately 100 compounds were characterized in both oils, with linalool being the major component of the flower oil (72.8%) and the leaf oil (80.1%), respectively. The most abundant minor components of the flower oil were α-terpineol (6.04%), β-phenylethyl alcohol (2.58%), β-pinene (2.39%), methyl 2-methylbutyrate (1.46%), geraniol (1.23%), and 1, 8-cineole (1.03%). The most abundant minor components of the leaf oil were β-caryophyllene (3.0%), β-elemene (1.7%), caryophyllene oxide (1.68%), and nerolidol (1.19%). Over 70% of the components characterized in the oils were found as trace constituents (<0.05%). Enantiomeric separation using chiral GC revealed that the absolute configuration of linalool was (R)-75%: (S)-25% and (R)-95.3%: (S)-4.7% for flower oil and leaf oil, respectively.
