Phytochemical studies on the fruits of Pieris formosa yielded two new grayanane diterpenoids, secopieristoxins A (1) and B (2), and their structures were elucidated on the basis of extensive analysis of NMR spectra, including two-dimensional NMR techniques. Compounds 1 and 2 were new highly acylated grayanane diterpenoids, of which ring B has suffered an oxidative cleavage between C-9 and C-10.
