Inhalation of scent compounds with phenylpropanoidal structures, such as trans-cinnamaldehyde, is expected to increase the appetite. The scent of curry powder is well known for its appetite-enhancing effect on humans. In this work, we show that the appetite of mice after inhalation of curry powder essential oil or benzylacetone showed a similar increase. The components of curry oil, trans-cinnamaldehyde, trans-anethole, and eugenol, each showed appetite-enhancing effects; therefore, these three scent compounds may be the active compounds in curry powder oil.

The aromatherapeutical potential of Piper guineense essential oil was investigated in mice via inhalation administration, and the active compounds were identified. An open field test and light/dark transition test were used to evaluate the sedative and anxiolytic activities of this essential oil, respectively. P. guineense essential oil showed significant sedative activity at an effective dose of 4.0×10−5 mg per cage compared to the control group. It also showed potent anxiolytic effect at a dose of 4.0×10−6 mg per cage. The main compounds of P. guineense essential oil were linalool (41.8%) and 3,5-dimethoxytoluene (10.9%). These two main compounds were shown to play a major role in the sedative activity of P. guineense essential oil. These results suggest that inhalation of P. guineense essential oil might induce a mild tranquilizing effect.
