摘要：

From the petrol and chloroform extracts of the aerial parts of Pterocaulon virgatum, two new coumarins, virgatenol and virgatol, were isolated, as well as the four known coumarins, 7-(3-methyl-2-butenyloxy)-6-methoxycoumarin, 7-(2,3-dihydroxy-3-methylbutoxy)-6-methoxycoumarin, ayapin (6,7-methylenedioxycoumarin) and scopoletin (7-hydroxy-6-methoxycoumarin). Their structures were elucidated on the basis of spectroscopic methods. (C) 1998 Published by Elsevier Science Ltd. All rights reserved.
