Abstract

Effects of volatiles from Pistacia chinensis Bunge and Juniperus chinensis cv. Kaizuka on human emotions were investigated. The volatiles were analyzed using a gas chromatograph-mass spectrometer (GC-MS). Human emotions were defined and measured using several physiological indices, including oxygen saturation of blood (OSB), finger temperature (FT), pulmonary ventilation volume (PVV), and electrocardiograph (ECG). These indices were measured using a multi-conductive physiology technique. The results showed that after participants had inhaled volatiles from P. chinensis Bunge, their OSB and FT decreased significantly (P<0.05) in comparison to the control group, while the PVV increased. After inhaling the volatiles from J. chinensis cv. Kaizuka, the OSB and FT increased, while the PVV decreased. In addition, women’s FT and PVV and men’s OSB and PVV differed significantly from those of the control group (P<0.05). Some ECG indices were also affected by the inhalation of volatiles. These results indicated that people tend to feel more excited or nervous when in the presence of P. chinensis Bunge, and more relaxed and comfortable while in the presence of J. chinensis cv. Kaizuka.
