and homononactic acids and their lactones, dilactones and tetralactones, five new compounds, namely homononactyl-nonactoate, a dilactone consisting of nonactic and homononactic acids and three cyclic trimers with nonactic and homononactic acids, were isolated from a strain of Streptomyces globisporus. Their structures, including the absolute configurations of the hydroxyl and methyl groups, were determined
除了已知的非壬酸和高壬酸类型的化合物及其内酯,双内酯和四内酯外,还有五种新化合物,即高壬酸-壬酸酯,由非乳酸和高壬酸组成的双内酯和三个带有三氟壬酸和非壬酸的环状三聚体。从球链霉菌(Streptomyces globisporus)菌株中分离得到。它们的结构,包括羟基和甲基的绝对构型,是通过广泛的光谱技术(例如UV,IR,MS,1D和2D NMR)确定的。
