A new indolopyridoquinazoline-type alkaloid from phellodendron amurense callus tissues
Callus tissue from the stems of Phellodendron amurense (Rutaceae) produced a new indolopyridoquinazoline-type alkaloid, 7, 8-dihydroxyrutaecarpine (2), together with known 7-hydroxyrutaecarpine (1). Their structures were established using spectroscopic methods.
