Four new 3,4-secocycloartane triterpenoids, pseudolactones A-D (1-4), were isolated from the ethanol extract of the cones of Pseudol arixamabilis. Their structures were established by extensive 1D- and 2D-NMR experiments. The cones of P. arixamabilis are enriched in the ring-expanded or cleaved cycloartane triterpenoids. This work provides new insight into cycloartane triterpenoids from the cones of P. arixamabilis.
从金钱松球果的乙醇提取物中分离得到了4个新的3,4-断环阿尔廷烷三萜类化合物,即假内酯A-D(1-4)。通过广泛的一维和二维核磁共振实验确定了它们的结构。金钱松球果富含环扩大或开环的阿尔廷烷三萜类化合物。这项工作为金钱松球果中的阿尔廷烷三萜类化合物提供了新的见解。
