ester of velutinal (i.e. compound 2b and 2a, respectively) as the only sesquiterpenoid. When the fruit bodies are injured the esters are enzymatically converted into sesquiterpene furans, mono- and di-aldehydes, and lactones, which have been isolated and their structures elucidated. These compounds have been submitted to conformational analysis by molecular mechanics and 1H NMR in order to make correct
研究了乳杆菌和苦瓜黄变和刺激性味道背后的化学背景。完整的子实体原本含有velutinal的(脂肪酸酯即化合物2B和图2a分别)作为唯一的倍半萜。当子实体受伤时,酯被酶转化为倍半萜烯呋喃,单醛和二醛以及内酯,这些酯已被分离并阐明了其结构。这些化合物已通过分子力学进行了构象分析,并且1为了进行正确的立体化学分配,使用1 H NMR。这两个物种的子实体的辛辣味道是由于新的二醛,金水晶(9)引起的,而新的三烯-内酯(8)与颜色的变化有关。
