Two new diterpenoids, pierisformoside A (1) and pierisformosin D (2), and two known diterpenoids, asebotoxins VIII (3) and V (4), were isolated from leaves of Pieris formosa. Their structures were elucidated on the basis of spectral analysis, including 1H-1H COSY, 13C-1H COSY, HMBC, and NOESY experiments.
