丁烯内酯，即3-甲基-2 H-furo [2，3-c]pyran-2-one（1），是烟雾中的一种主要化合物，负责促进多种植物物种的种子萌发。我们现在报告的5个烷基取代的变体1的结构，也存在于烟雾中。这些类似物的浓度，以及1，在一个典型的烟雾-水溶液中已确定使用高效液相色谱（HPLC）纯化，然后通过气相色谱-质谱（GC-MS）分析。类似物3，5-二甲基-2H-呋喃并[2，3-c]吡喃-2-酮（3）的含量表明，它有助于粗烟提取物的整体萌发促进活性。
The butenolide, 3-methyl-2H-furo[2,3-c]pyran-2-one (1), is a major compound in smoke responsible for promoting the seed germination of a wide range of plant species. We now report the structure of five alkyl substituted variants of 1 that are also present in smoke. The concentrations of these analogues, as well as that of 1, in a typical smoke-water solution have been determined using high-performance liquid chromatography (HPLC) purification followed by gas chromatography-mass spectrometry (GC-MS) analysis. The analogue, 3,5-dimethyl-2H-furo[2,3-c]pyran-2-one (3), was identified at levels that indicate that it is a contributor to the overall germination-promoting activity of crude smoke extracts.
