| Research Abstract |
Changes of orexin level in brain could effects on not only food intake but also the characteristics of feeding behavior with accompanying masticatory muscle activities. These results suggest that regulation of orexin level is one of factors that control feeding behavior. Only sniffing the fragrance of Osmanthus fragrans did not change blood glucose level, but when glucose was taken into the body simultaneously, the fragrance shifted the blood glucose curve to the left and reduced the serum amylase value in saliva. We conclude that this fragrance can retard digestion and/or absorption of glucose through the activation of the parasympathetic nervous system.
