摘要：

The known 7,8-secolabdane type diterpenoids neopallavicinin (1), pallavicinin (2). and 18-hydroxypallavicinin (3) were isolated from Pallavicinia ambigua, and their structures were determined. The X-ray crystal structure of 1 was solved, and, in combination with CD and NMR studies, the absolute configurations of 1-3 were established. A possible biogenetic pathway for 1 and 2 from a single labdane precursor is proposed.
