摘要：Volatile compounds of Rosmarinus eriocalyxsamples were extracted by steam-hydrodistillation (HD) and microwave-assisted hydrodistillation (MAH). GC-MS and GC-FID analysis of the oils revealed the presence of 22 and 26 compounds in the essential oils obtained through HD and MAH, respectively. The total yield of the volatile fractions obtained through HD and MAH was 1.21% and 1.47%, respectively. The two oils contained the same dominant components: camphor (35.92% HD; 35.33% MAH), camphene (19.74%; 17.07%), α-pinene (14.53%; 12.87%), and 1,8-cineol (6.52%; 6.73%). Higher amounts of oxygenated monoterpenes such as borneol, 1,8-cineol, isobornyl acetate, α-terpeneol, caryophyllene oxide (13.59%) were present in the oil of MAH in comparison with HD (12.36%). However, HD oil contained more monoterpene hydrocarbons such as tricyclene, α-pinene, camphene, o-cymene and limonene (39.04%) than MAH extracted oil (34.45%).
