Abstract

The volatile constituents of the essential oil of wild Melissa officinalis L. obtained from the Kurdistan province of Iran were extracted by headspace/solid-phase micro-extraction and were analysed by gas chromatography and gas chromatography/mass spectrometry. Of a total of 14 compounds in the oil, 12 (85.7%) were identified. The main components were as follows: (E)-citral (37.2%), neral (23.9%) and citronellal (20.3%). Some physicochemical properties, such as the logarithm of calculated octanol-water partitioning coefficients (log K (ow))(,) total biodegradation (TB (d) in mol h(-1) and g h(-1)), water solubility (S (w), mg L(-1) at 25°C) and median lethal concentration 50 (LC(50)), were calculated for compounds 1-14 from M. officinalis L.

摘要

从伊朗库尔德斯坦省获得的野生蜜蜂花精油的挥发性成分通过顶空/固相微萃取提取，并通过气相色谱和气相色谱/质谱进行分析。在油中的总共 14 种化合物中，鉴定了 12 种（85.7％）。主要成分如下：（E）-柠檬醛（37.2％），橙花醛（23.9％）和香茅醛（20.3％）。计算了一些理化性质，例如辛醇-水分配系数的对数（log K（ow））（，）总生物降解（TB（d）以 mol·h（-1）和 g·h（-1）表示），水溶解度（S（w），25°C 时的 mg·L（-1））和半数致死浓度 50（LC（50）），从蜜蜂花 L.计算了化合物 1-14。
