A new pimarane-type diterpenoid from moss Pseudoleskeella papillosa (Lindb.) Kindb

A new pimarane-type diterpenoid, momilactone C (1), together with one known compound, momilactone A (2), was isolated from moss Pseudoleskeella papillosa by column chromatography on silica gel, Sephadex LH-20 and semi-preparative HPLC. Their structures were established on the basis of HR–ESI–MS, 1D and 2D NMR spectroscopic methods. Allelopathic test showed that the two diterpenoids inhibited germination of the Arabidopsis thaliana seeds.
