Nardia succulenta and N. scalaris afforded a series of 12 diterpene malonates: ent-kaur-16-en-15β-yl hydrogen malonate; ent-labda-8(17),13-dien-15-yl hydrogen malonate; bis-ent-kaur-16-en-15β-yl malonate; bis-ent-labda-8(17),13-dien-15-yl malonate; ent-kaur-16-en-15β-yl ent-labda-8(17),13-dien-15-yl malonate; ent-kaur-16-en-15β-yl phytyl malonate; 14-ent-kaur-16-en-14-yl hydrogen malonate; bis-14-ent-kaur-16-en-14-yl malonate; (14R)-ent-kaur-16-en-14-yl phytyl malonate; (14R)-ent-kaur-16-en-14-yl epi-bornyl malonate; ent-kaur-16-en-15-yl epi-bornyl malonate and (14R)-ent-kaur-16-en-14-yl fenchyl malonate; besides (1,2)-bis-nor-phytone and two diastereomeric 3,6-peroxo-cupar-1-enes. Key words: Nardia succulenta; N. scalaris; Jungermanniales; liverworts; kauranes; labdanes; malonates.
