Abstract
Three squalene-type triterpenoids named concentricols B, C and D (1-3) were isolated from the ethyl acetate extract of fruiting bodies of the xylariaceous ascomycete Daldinia concentrica. Their absolute structures were elucidated by analysis of 2D NMR, MS, IR and UV spectra, and the modified Mosher's method.
摘要
从炭角菌科子囊菌同心炭团菌（Daldinia concentrica）子实体的乙酸乙酯提取物中分离出三种角鲨烯型三萜类化合物，命名为同心菌素B、C和D（1-3）。通过二维核磁共振（2D NMR）、质谱（MS）、红外光谱（IR）、紫外光谱（UV）分析以及改良的莫舍尔方法确定了它们的绝对结构。
