Coumarin occurs in many plants used as flavoring and is known to possess hepatotoxic effects. Despite in the EFSA ‘Compendium of botanicals containing toxic substances’ coumarin is reported to be present in Melittis melissophyllum (bastard balm), a plant traditionally used as beverage in Italy and Serbia, to the best of our knowledge quantitative data has never been reported. Thus, the amount of coumarin in bastard balm leaves and its variation during the annual phenological cycle were determined. The subsp. melissophyllum resulted to contain high levels of coumarin (14,392 mg/kg), mainly in the early stages of the plant cycle, suggesting prudence in its use as beverage. Furthermore, coumarin was found to be useful as marker compound to differentiate the bastard balm subspecies occurring in Italy, since the subsp. albida contained a much lower content of this molecule (19–34 mg/kg). 相似文献

为建立利用双指纹图谱溯源进口霞多丽干白葡萄酒产地的方法。通过使用气相色谱—质谱(GCMS)建立了进口霞多丽干白葡萄酒二氯甲烷提取物的特征指纹图谱,使用液相色谱-二极管阵列检测器-质谱(HPLC-DAD-MS)建立了进口霞多丽干白葡萄酒乙酸乙酯提取物的特征指纹图谱,方法精密度、重现性、稳定性好,符合指纹图谱评价技术的要求。利用SPSS 19.0软件对生成20种不同产地霞多丽干白葡萄酒的双指纹特征图谱进行聚类分析,分析结果能够准确的溯源进口霞多丽干白葡萄酒产地。结果表明:将两种特征指纹图谱结合起来,通过多元数据分析可以实现快速、简单、有效溯源进口霞多丽干白葡萄酒的产地。 相似文献
