“…Since 1982 [40], we reported the distribution of a number of new sesquiand diterpenoids and naphthalens, alkylphenols and bis-bibenzyls in NZ liverworts, Balantiopsis, Chiloscyphus, Lepidolaena, Monoclea, Plagiochila, Porella, Radula, Schistochila, Trichocolea, and Wettsteinia species [6][7][8]40]. Recently, Balantiopsis [41], Chiloscyphus [42], Frullania [43][44][45][46], Jamesoniella [41], Jungermannia [47,48], Lepidozia [49], Radula [41,50], Plagiochila [51], Schistochila [52], Trichocolea [53] and Tylimanthus [54] species were chemically analyzed. The following is the chemical constituents of selected liverworts endemic to NZ.…”

“…The New Zealand F. falciloba belongs to chemotype V of the Frullaniaceae, since it elaborates characteristic bazzanane-type sesquiterpenoids ( 27-29 ), with no sesquiterpene lactones having been detected. 35 Bazzanenones A-D have been isolated from an unidentified New Zealand Frullania species. 41 The bazzanane sesquiterpenoids have been also found in F. squarrosula .…”

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.

“…These sesquiterpenes have been isolated from a New Zealand liverwort, Frullania falciloba. 113 A new sesquiterpene, 3,7-dihydroxydihydrolaurene 136, has been obtained from the red alga Laurencia obtusa, whilst a dimeric sesquiterpene of the cyclolaurane type 137 was isolated from Laurencia microcladia. These algae had been collected from the coastal rocks of Serifos in the Aegean Sea.…”
