New geranyloxycoumarins from Toddalia asiatica.
A phytochemical study on the twigs of Toddalia asiatica led to the isolation of two new geranyloxycoumarins, 7-geranyloxy-5-methoxycoumarin (1) and 8-geranyloxy-5,7-dimethoxycoumarin (2). Their structures were elucidated on the basis of extensive spectroscopic analysis.
