Three new polyacetylated labdane diterpenoids ptychantins P-R (1-3) and four known compounds (4-7) were isolated from an EtOH extract of the Chinese liverwort Ptychanthus striatus (Lehm. & Lindenb.) Nees. Their structures were established by extensive analysis of spectroscopic data (IR, UV, HRESIMS, 1D NMR, and 2D NMR).
