为了研究岗松露化学成分及其杀菌作用,并与岗松(精)油的化学成分进行对比分析,以便为岗松露的开发与利用提供科学依据.本研究采用气相色谱-质谱分析技术对岗松露中的挥发性化学成分进行分析鉴定,并采用面积归一化法测定主要化学成分的相对含量,最后通过消毒杀菌实验检测岗松露对菌落群数的影响.结果显示,岗松露中含挥发性成分约0.2％;从岗松露中分离鉴定出30多种化学成分,占色谱总馏出峰面积的90％以上;岗松露能明显减少或消灭菌落群.岗松露具有杀菌作用,可开发作为天然的医药保健、灭菌消毒、洗涤、清洁等新产品.“,”The chemical constituents and bactericidal effects of the distillate medicinal water of Baeckea frutescens L.were studied and compared with the chemical constituents of the essential oil from Baeckea frutescens L，which provided a scientific foundation for the development and utilization of the distillate medicinal water of Baeckea frutescens L. The volatile chemical constituents in the distillate medicinal water of Baeckea frutescens L.were analyzed and identified by gas chromatography-mass spectrometry. The relative contents of the main constituents were determined by area normalization method. Through the disinfection experiment， the effect of the distillate medicinal water of Baeckea frutescens L.on the number of colonies was examined. The results showed that the volatile ingredients in the distillate water of Baeckea frutescens L.were 0 .2% approximately and more than 30 constituents were isolated and identified from the distillate medicinal water，accounting for over 90% of the total peak area of the chromatogram. The distillate medicinal water of Baeckea frutescens L.could significantly reduce or eliminate the number of colonies. The distillate medicinal water of Baeckea frutescens L.has a bactericidal effect and could be developed as a natural healthcare medicine，sterilizing，washing，cleaning and other new products.
