广西芳樟醇型樟树精油指纹图谱研究

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。

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

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.
