Appetite-Enhancing Effects of Curry Oil
Biological and Pharmaceutical Bulletin
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
... refore, these three scent compounds may be the active compounds in curry powder oil. Key words curry oil; inhalation; appetite-enhancing effect; spice Inhalation of trans-cinnamaldehyde, which is abundant in cinnamon essential oil, 1) and its analogue benzylacetone, increases food intake in mice. 2) Both trans-cinnamaldehyde and benzylacetone contain the analogue moiety of phenylpropanoids, and our previous results indicate that phenylpropanoidal compounds possibly have appetite-enhancing effects. Curry powder consists of various spices, such as cinnamon, cloves, and fennel, that contain phenylpropanoids as their main oil components. 3, 4) The scent of curry powder is well known for its appetite-enhancing effects in humans, and in this work, we examine the appetite-enhancing effects in mice of inhaling the scent of curry powder, some of its essential oil components, and analogues of the components.
