Psychological and Physiological Human Responses of Rose Aroma

采用15个双极评定量表和2个单极评定量表对6个现代玫瑰品种的香味进行语义差异评价。作为因子分析的结果，提取了以下三个因素：a)综合评价，b)质量和c)强度。其中蓝色气味被评价为男女得分最高的。通过测量唾液中淀粉酶的活性来检验玫瑰挥发性成分对压力建立运动责任感的影响。这些结果表明，在解除运动责任后，玫瑰挥发性成分的活性最高，并随着时间的推移逐渐下降，而且也观察到比休息时间减少。此外，通过心电和脑电检查玫瑰挥发性成分对精神应激的影响。对有效印象、强化印象、疲劳印象和张力印象也进行了主观测量。这些结果表明，当给予玫瑰挥发性成分时，脑电中α节律的比例显著降低，而β节律的比例显著增加。心电图中的平均心率与玫瑰香味的存在无关。主观评定量表的紧张印象得分差异有统计学意义。

The scents of 6 modern roses were evaluated using 15 bi-pole and 2 mono-pole rating scales in semantic differential. As the result of factor analysis, following three factors were extracted : a) comprehensive valuation, b) quality and c) intensity. The blue scent is evaluated among them with a highest score in both sexes.The effects of rose volatile components on stress built up the exercise responsibility were examined by measuring amylase activity in saliva. These results suggested that the activity was highest just after removing the exercise responsibility and decreased gradually in time-course, and that also observed to reduce than that of repose time.Furthermore, the effects of rose volatile components on mental stress were examined by using an electrocardiogram and electroencephalogram. The effective, intensive, fatigue and tensional impressions were also subjectively measured. These results indicated that the ratio of alpha rhythm was significantly reduced and that of beta rhythm was increased in electroencephalogram, when the rose volatile component was given. The average of heart rate in electrocardiogram was independent of the presence of rose scents. There was statistically significant difference in the tensional impression of subjective evaluation scales.
