| Abstract: | Objective] The aim was to analyze volatile aromatic compounds from tea leaves in nature and its effect on human brain waves. Method ] Natural volatile aromatic components of fresh tea leaves which had spread for 4 h at room temperature were analyzed by dynamic head- space collection and thermal desorption system/gas chromatography/mass spectrum （TDS-GC/MS）. The effect of the spreading fresh tea leaves on human brain waves were determined by biofeedback instrument. Result ] The volatile aromatic components of spreading fresh leaves were mainly the compounds of esters and terpenes. Aromatic components could increase significantly the Alpha amplitude. Furthermore, the volatile aromatic components of fresh tea leaves has the efficacy of relaxing the body and the mind. Conclusionl The study provided a reference for the application of tea in aromatheranv. |
