通过GC/MS对2种植物复方精油进行测试, 明确主要化合会物种类。招募有焦虑情绪的志愿者, 以志愿者的焦虑自评量表(SAS)和脑电波变化情况为指标, 评价这2种复方精油对于焦虑情绪的缓解效果。结果表明:①2种复方精油的组成成分均以烯类化合物为主, 辅以酯类和醇类化合物。②通过焦虑自评量表统计, 嗅吸2种复方精油7 d后, 男性和女性志愿者的得分有一定程度下降。复方精油II嗅吸过程中的得分下降程度要大于复方精油I, 在缓解志愿者焦虑情绪的主观评价中更有效。③在脑电波实验中, 复方精油II对志愿者α波增强的人数比例高, 效果相对更好。综合焦虑自评量表和脑电波测试结果得出, 复方精油II的缓解焦虑效果比复方精油I效果更显著, 某些单方精油在复方精油中的比例低, 但是对缓解焦虑情绪有协同作用。

The chemical composition of compound essential oil I and compound essential oil II were analyzed by gas chromatography/mass spectrometer.Volunteers were recruited to evaluate the two compound essential oils for the treatment of anxiety by self-rating anxiety scales(SAS)and electroencephalogram changes.Terpenes were the most abundant compounds in the twocompound essential oils.According to self-rating anxiety of the volunteers, the male and female volunteer’s scores were all dropped after 7 days’ compound essential oil sniffing tests.Compound essential oil II was more effective than compound essential oil I as it had greater degree of drop.In the electroencephalogram experiments, the volunteers with compound essential oil II sniffing tests had a higher proportion of α wave enhanced.
