Progress in Essential Oils

摘要

In addition, trace amounts (< 0.05%) of 2-hexanol, 3-buten-2-ol, (Z)-3-hexenol, 2-heptanone, 2-heptanol, a-thujene, camphene, a furanoid form of cis-linalool oxide, 2-decanol, perilla ketone, linalyl acetate, thymol, a sabinyl acetate isomer, tetradecane and cin-namyl cinnamate were found in this oil. Marongiu et al. (2002) produced a supercritical fluid CO2 extract of turmeric rhizomes (available commercially in Italy) at 50°C, 90 bar and a CO2 flow of 1.5kg/hr. In addition, the authors also produced an oil from the same batch of rhizomes by hydrodistillation. The analytical results of the extract and oil, as determined by GC/MS only, can be seen in T-1.
