title: Bioactive kaurane diterpenes and coumarins from Fortunella margarita.
abstract: Two bioactive pyranocoumarins 1 (sesselin) and 3 (xanthyletin) and one prenylated coumarin 2 (suberosin), beside three rare kaurene diterpenes 5-7 were isolated from the roots of Fortunella margarita. Their structures were determined from their spectroscopic data, including 1H/13C 2D NMR experiments. The kaurene diterpenes 5-7 are reported in Rutaceae for the first time. Diterpene 5 was found to be a potent stimulator of uterine contraction; it also caused stimulation of brain activity.
