【摘要】 目的:分析湖北五峰产野菊花挥发性化学成分。方法:采用水蒸气蒸馏法提取野菊花挥发性成分,利用气相色谱-质谱联用(GC-MS)分析其化学组成,并通过峰面积归一化法计算各成分的相对质量分数。结果:湖北五峰产野菊花共分离出81种组分,鉴定71种挥发性化学成分,与其他4个地区比较具有10种独特主要成分。含量最高的是L-樟脑5.840%,其次是氧化石竹烯5.807%、左旋-乙酸龙脑酯5.551%、油酸4.873%及龙脑4.668%。结论:湖北五峰产野菊花与其他地区野菊花挥发性化学成分及含量存在明显差异。更多还原

【Abstract】 Objective: Analysis of Hubei Wufeng producing Chrysanthemum indicum volatile chemical composition.Method: The volatile chemical composition in Hubei Wufeng producing C.indicum was extracted by steam distillation,and then the composition was analyzed by GC-MS.Chromatographic peak area normalization method was used to calculate the relative mass fraction of each ingredient.Result: The results showed that 81kinds of ingredients were isolated from C.indicum,71 kinds were identified,and 9 unique kinds were identified in comparison with the other four regions.L-camphor was highest content,which was up to 5.840%,followed by caryophyllene oxide 5.807%,(-)-bornyl acetate 5.551%,oleic acid 4.873% and endo-borneol 4.668%.Conclusion: There is a significant difference in volatile chemical composition and content between Hubei Wufeng producing C.indicum and other regions.更多还原
