From Radula laxiramea, 12 bibenzyl derivatives and the common bisbibenzyl perrottetin E were isolated. Two compounds are described for the first time as natural products, and one, previously only known after derivatisation, was found in genuine form . Perrottetinene, a cannabinoid from a liverwort is worth mentioning.
From the liverwort Porella canariensis, collected in Madeira, Portugal, nine pinguisanes, four drimanes, including the pungent polygodial, two germacranes, and two aromadendranes were isolated. The major compounds were the arom adendrane ent-cyclocolorenone and the nor-pinguisane norpinguisone. Three hydrocarbons were isolated by low temperature column chrom atography. One germacrane and one pinguisane proved to be new natural products.
