, p. 3124 - 3126 (2007/10/02)

Four new diterpenoids, pieristoxins H(I), I(II), J(III) and K(IV), were isolated from the leaves of Pieris japonica D.Don, together with the known diterpenoids, asebotoxin IV(XI) and VII(XII).The chemical structures of I and II were established to be 7-O-hydroxy and 14-O-lactoyl grayanotoxin III, respectively.III and IV were shown to be esters of pieristoxin G(VI), one of the most highly oxygenated grayanoids.Keywords---Pieris japonica; Ericaceae; asebi; diterpenoids; pieristoxin H; pieristoxin I; pieristoxin J; pieristoxin K; grayanoid; toxin
