This study was performed for effects on metabolism and electroencephalography by volatile compounds in basil(Ocimum basilicum). As a result of proximate composition analysis of basil, 88.53±0.88% of moisture, 7.28±0.89% of carbohydrate, 2.13±0.15% of protein, 1.80±0.03% of ash and 0.26±0.02% of lipid were determined. The highest content of constituent amino acids and free amino acids in basil was glutamic acid and aspartic acid were followed. The total phenol contents of basil essential oil(BEO) were analyzed to be 0.26±0.01 mg/mL. The antioxidant activity of 2,2-diphenyl-1-picrylhydrazyl(DPPH) and 2,2'-azino-bis3-ethyl benzo–thiazoline-6-sulphonic acid(ABTS) in BEO were 32.00±1.84% and 78.50±1.49% respectively. The volatile compounds in basil and BEO were analyzed using solid phase micro extraction(SPME) and gas chromatography-mass spectrometry(GC/MS). Linalool was major compound in both basil and BEO and eugenol and menth-4-ene were followed. Electronic nose(E-nose) was used to measure the flavor characteristics of basil and BEO. Basil was richer in ammonia and BEO had a higher concentration of hydrogen sulfide. In vivo study using rat model were carried out to investigate the changes in vivo caused by inhalation of BEO. The 4 groups were divided according to the inhalation conditions into unflavored group(Control), group of inhaling the 1% linalool for 5 min(Positive), 1% BEO for 5 min(5min) and 1% BEO for 20 min(20min). Food intake and body weight were measured by once a week during feeding. As a result of food intake, no significantly different(P>0.05) were investigated among groups in all weeks and result of weight, the control group was highest in the final week and the 20min group was lowest in the same week. Sucrose(1%) intake test and forced swimming test were performed by once a week as behavioral experiments about depression. The sucrose intake was increased in all groups but the increase of positive group was higher than that of other groups. The forced swimming test showed that immobility time decreased in all groups. During same period, blood pressure of animals was measured by once a week. In all groups except for the control group, systolic blood pressure increased. Also, diastolic blood pressure increased and pulse rates decreased in all groups. Serum and organs were obtained after the sacrifice of animals and measured the weight of organs. Weight of brain tissues and kidney tissues were highest in 5min group and white adipose tissues were highest in control group and lowest in positive group. Total cholesterol, high density lipoprotein(HDL) and triglyceride(TG) were measured in the serum. The total cholesterol, low density lipoprotein(LDL) and TG contents were the highest in the control group whereas HDL content was the lowest. It was the opposite in the 20min group. Glutamic-pyruvic transaminase(GPT) and glutamic oxaloacetic transaminase(GOT) contents in the serum were measured to investigate the hepatotoxicity in liver using the serum. GPT was the highest in the control group and GOT was not significant difference(P>0.05) in all groups. Cortisol and serotonin contents in the serum were measured and not significantly different(P>0.05) among groups. However, compared by average, cortisol content was the highest in the control group and lowest in the positive group and the serotonin content was the opposite. Electroencephalography(EEG) and blood pressure of 12 subjects were measured before and after inhalation of 1% BEO. The 10 data were selected by head-tail cut and analyzed by dividing to theta, alpha, beta, and gamma waves and to absolute power and relative power. As a result, theta wave and alpha wave decreased and beta wave and gamma wave increased. These results suggest that after inhalation of 1% BEO, relaxation of the accident, increase of mood and cognition and activation of consciousness appeared. As a result of the blood pressure, there are a few significantly different(P<0.05). However, compared by average, systolic, diastolic blood pressure and pulses decreased after the inhalation. The amount of cortisol in the saliva was measured before and after inhalation of 1% BEO and significantly increased in 30% of the subjects(P<0.05). This result can be used as a basic data for the study about physiological function of basil and basil essential oil as aromatherapy based on the physicochmical, in vivo study by rat model and clinical approach.
