Abstract
Three new diterpenoids, pierisformosides G-I (1-3) and a diphenylamine derivative 4 have been isolated from the ethanol extract of Pieris formosa leaves, compound 1 being a new type seco-ring-A kaurane diterpene glucoside. Their structures were elucidated with the aid of NMR spectroscopy including two-dimensional-NMR techniques.Entities:
