| Abstract: | "Distribution of volatile constituents in the essential oil of nutmeg obtained by simultaneous distillation extraction (SDE), high vacuum distillation (HVD) and super critical fluid extraction (SFE) was compared with reduced pressure distillation (RPD) and head space (HS) analysis. HS and RPD volatiles were characterized by a high content of sabinene, followed by alpha-pinene and beta-pinene. Interestingly, unlike the SDE, HVD and SFE oils, distillates from HS and RPD were marked by the absence of phenolic ethers namely myristicin, elemicin and safrole. The HS and RPD volatiles possessed a pleasant nutmeg aroma indicating a significant role of terpenic constituents in contributing to the top aroma note. GC-olfactometry (GC-O) of the oils aided in establishing the role of sabinene, alpha-pinene and beta-pinene in contributing to the distinctive note of the spice. A high odor activity value (OAV) of sabinene and alpha-pinene established the role of these two constituents in imparting the characteristic nutmeg odor" |
