广西芳樟醇型樟树精油指纹图谱研究

Study on Fingerprints of Essential Oil from Linalool Type of Cinnamomum camphorastem in Guangxi Province

目的:利用气相色谱-质谱(GC-MS)联用技术建立广西芳樟醇型樟树精油的指纹图谱分析测试方法,为其质量控制提供理论依据。方法:采用GC-MS法对广西道地产区的14批次广西芳樟醇型樟树精油样品进行比较分析,并进行相似度计算。结果:广西芳樟醇型樟树精油指纹图谱检测出14个共有特征峰,特征峰峰面积之和占总峰面积的95%以上,14批次样品具有较高的相似度;建立的广西芳樟醇型樟树精油GC-MS分析方法有较好的重复性、精密度和稳定性,RSD均小于3%。结论:14批次广西芳樟醇型樟树精油的指纹图谱中各成分均得到了较好分离,具有特征性和唯一性,且该方法准确可靠,重复性好,可作为广西芳樟醇型樟树精油的质量控制方法。

Objective： To establish the method of fingerprint analysis on essential oil from linalool type of C.camphorastem in Guangxi province by GC-MS to provide reference for quality control of them.Method： GC-MS analysis was performed for 14 samples of genuine producing areas in Guangxi from linalool type of Cinnamomum camphorastem,and similarity is calculated by data processing function of Excel.Result： The 14 feature peaks in fingerprints of essential oil from linalool type of C.camphorastem in Guangxi province were sepanted and identified over 95% of total area of the peaks.The similarity was higher among 14 samples（ 90%）.RSD of precision,repeatability and stability is less than 3%.Conclusion： The method is precise and reliable,which can be used for quality control and identification of essential oil from linalool type of C.camphorastem in Guangxi province.
