摘要：

Two new grayanane diterpenoids named pierisformosins B and C, together with a known asebo-toxin IV were isolated from leaves of Pieris formosa. Their structures were elucidated based on spectral analysis, including H-1-H-1 COSY,C-13-H-1 COSY, HMBC and NOESY experiments. (C) 1998 Elsevier Science Ltd. All rights reserved.
