“…41 The bazzanane sesquiterpenoids have been also found in F. squarrosula. 14,52 Chemical analysis of the New Zealand Frullania falciloba from different collections showed the presence of β-bazzanene ( 27), but no other bazzananes were detected. This species produces 3-methoxy-3′,4′-methylenedioxybibenzyl (35), as the main component, along with the fusicoccane diterpenoid, fusicogigantepoxide.…”

Frullania is one of the largest and taxonomically most complex genus of leafy liverworts. Current morphology-based estimates of Frullania diversity are close to 400 species; however, species level-classification of Frullania has been regarded notoriously difficult and subject to many studies. The liverworts classified in this genus have been studied using morphological evidence and molecular markers but also in terms of secondary metabolite composition. Up to now 98 Frullania species have been chemically investigated. As a result, it is known that Frullania species are characterized by a remarkable chemical diversity. The most characteristic compounds present in this liverwort genus are sesquiterpene lactones with eudesamnolides as the most diverse group, and aromatic compounds belonging to bibenzyls. In this review paper we report the distribution of secondary metabolites in all chemically investigated Frullania species and discuss some aspects concerning the division of this genus into chemotypes.

“…[ 9 , 10 , 11 ]. Others, Trichocolea mollissima, T. tomentella and T. lanata , possess prenyl-phenyl ethers that are mildly fungicidal [ 12 , 13 ]. Recently, a structural study aimed at understanding the structure of early land plants through the comparison of the tube and cell-sheet from Cambrian-to-Devonian microfossils with experimentally degraded modern liverworts, suggested that the presence of phenolic compounds was responsible for the protection of lower epidermal tissues from the soil microbe attack, and provided dimensional stability to the remains of early marchantioid liverworts similar in some ways to modern Marchantia and Conocephalum [ 14 ].…”

Usually regarded as less evolved than their more recently diverged vascular sisters, which currently dominate vegetation landscape, bryophytes seem having nothing to envy to the defensive arsenal of other plants, since they had acquired a suite of chemical traits that allowed them to adapt and persist on land. In fact, these closest modern relatives of the ancestors to the earliest terrestrial plants proved to be marvelous chemists, as they traditionally were a popular remedy among tribal people all over the world, that exploit their pharmacological properties to cure the most different diseases. The phytochemistry of bryophytes exhibits a stunning assortment of biologically active compounds such as lipids, proteins, steroids, organic acids, alcohols, aliphatic and aromatic compounds, polyphenols, terpenoids, acetogenins and phenylquinones, thus it is not surprising that substances obtained from various species belonging to such ancestral plants are widely employed as antitumor, antipyretic, insecticidal and antimicrobial. This review explores in particular the antifungal potential of the three Bryophyta divisions—mosses (Musci), hornworts (Anthocerotae) and liverworts (Hepaticae)—to be used as a sources of interesting bioactive constituents for both pharmaceutical and agricultural areas, providing an updated overview of the latest relevant insights.

“…Many liverworts are endemic to the southern hemisphere, including Oceania and South America. Recently, we have reported the structures of new sesqui- and diterpenoids from New Zealand liverworts [ 3 ]. We also reported the isolation of new sesquiterpenoids 1 and 2 from an unidentified Gackstroemia species from New Zealand [ 4 ].…”

A new rosane diterpenoid, 3α-hydroxy-5,15-rosadien-11-one (3), was isolated, together with a known rosane diterpenoid, 5,15-rosadiene-3,11-dione (4), and an aromadendrane sesquiterpenoid, ent-cyclocolorenone (5), from the Et2O extract of an unidentified Argentine liverwort Anastrophyllum species. Moreover, four known sesquiterpene lactones 6–9 and two known bibenzyls 10, 11 were isolated from the Et2O extracts of Argentine Frullania brasiliensis and Radula voluta, respectively. The structures of compounds 3–11 were determined by the use of NMR techniques.
