Diterpenoids and Aromatic Compounds from the Three New Zealand Liverworts Jamesoniella kirkii, Balantiopsis rosea, and Radula Species.

摘要

Three new aromatics were isolated from the New Zealand liverwort Balantiopsis rosea. A new bibenzyl was isolated from an unidentified Radula species, together with known bibenzyls. Jamesoniella kirkii yielded three known ent-isopimarane and two ent-kaurane diterpenoids. Their structures were confirmed by NMR techniques, chemical reaction, and X-ray crystallographic analysis.
