The structure of the major component isolated from fraotion B of the Pieria fel-tarrae Lour extract has already been determined as 1.The presont paper reports the struoture of the other two new aglyoones,piofeltarraegenin Ⅱ (2) and piofeltarraegenin Ⅲ(8).In comparison of the spectroseopio data (UV,IR,1HNMR,13C NMR and MS) of piofeltarraegenins Ⅱ and Ⅲ with those of 1 followed by chemical reactions,their structures are assigned as 2 and 8 respectively.
