sesquiterpenoid contents of the fruit-bodies of Lactarius deliciosus Fr. and L. deterrimus Grobger have been reinvestigated. Undamaged fruit-bodies of both species were found to contain only a single sesquiterpene, as two fatty acid esters. If the fruit-bodies are injured (e.g. by cutting), the esters are in minutes converted to five free sesquiterpenes. Three of these have previously been isolated from
摘要 Lactarius deliciosus Fr 子实体的倍半萜类化合物含量。和 L. deterrimus Grobger 已被重新调查。发现这两个物种的未损坏子实体仅含有一种倍半萜烯,即两种脂肪酸酯。如果子实体受损(例如通过切割),酯会在几分钟内转化为五个游离的倍半萜。其中三个先前已从 L. deliciosus 中分离出来,而两个是新化合物,并且已通过光谱和化学方法阐明了新化合物的结构。受损子实体中倍半萜烯的转化似乎是酶促的,并且讨论了它们是化学防御系统一部分的可能性。
Total Synthesis of Azulene Derivative, a Blue Pigment Isolated from <i>Lactarius indigo</i>, and Colorant Application of Its Aqueous Dispersion
investigated a fat-soluble azulene derivative isolated from the mushroom Lactarius indigo as a potential candidate for a natural blue colorant. We developed its first total synthesis, where the azulene skeleton was constructed from a pyridine derivative and an ethynyl group was converted into an isopropenyl group using zirconium complexes. Moreover, nanoparticles of the azulene derivative were prepared
