Abstract: | "The essential oils from aerial parts of Elatostema laetevirens and Elatostema umbellatum var. majus were investigated by capillary GC and GC-MS. The important aroma-active compounds were also detected in the oil using GC-MS/O and aroma extraction dilution analysis (AEDA). As a result, 79 compounds of E. laetevirens and 80 compounds of E. umbellatum var. majus, accounting for 95.41% and 98.37%, were identified, respectively. The major components of E. laetevirens oil were phytol (667.4 microg/100 g fresh samples), neophytadiene (335.2 microg) and gamma-himachalene (49.8 microg). On the other hand, E. umbellatum var. majus oil contained phytol (402.3 microg), linoleic acid (289.4 microg) and palmitic acid (241.4 microg) as the major components. GC-MS/O and AEDA showed that (2E)-hexenal and (2E, 4E)-nonadienal were most aroma compounds of E. laetevirens oil. It seems that these components make the green-floral odor. On the other hands, it seems that (2E)-hexenal, (3Z)-hexenol and 1-octen-3-ol make the green-oily odor of E. umbellatum var. majus oil" |
