“…From this essential oil amorpha-4,9-dien-14-al (13) and 7,14anhydroamorpha-4,9-diene were isolated, among others [41]. These data are in accordance with the other reports concerning chemistry of this liverwort species [42,43]. Shy and Wu [43] divided L. fauriana into three chemotypes: amorphane (I), chiloscyphane (II), and eudesmane (III).…”

Studies concerning chemical profiling of the volatiles present in the solvent extracts from liverworts help to determine inter-and intraspecific relationships in this plant group. Due to the fact that the liverworts are morphologically very small and it is difficult to collect their sufficient amounts, there are still a few data concerning the chemistry of essential oils. The available data indicate however, that the components present in the essential oils can be used in chemosystematic studies of these spore-forming plants. Compounds occurring in the essential oils constitute a powerful tool for studying chemical differences between or within liverwort species for which the characteristic components are mono-and sesquiterpenoids. Good results were obtained for the liverworts species from the genera Asterella,

“…In liverworts, essential oils may partly be responsible for this activity [ 13 ]; however, in several cases, active components have been identified from the involatile fraction. Sacculatal from Pellia endiviifolia showed potent antibacterial activity against Streptococcus mutans [ 14 ], lepidozenolide from Lepidozia fauriana showed activity against methicillin-resistant Staphylococcus aureus (MRSA) [ 15 ], and marchantins from many Marchantia species showed activity against more than 10 pathogen bacteria [ 16 , 17 ]. Herbertane sesquiterpenoids were active against Staphylococcus aureus , Klebisella pneumoniae , and Bacillus subtilis [ 18 , 19 ].…”

One-hundred and sixty-eight aqueous and organic extracts of 42 selected bryophyte species were screened in vitro for antiproliferative activity on a panel of human gynecological cancer cell lines containing HeLa (cervix epithelial adenocarcinoma), A2780 (ovarian carcinoma), and T47D (invasive ductal breast carcinoma) cells using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and for antibacterial activity on 11 strains using the disc-diffusion method. A total of 99 extracts derived from 41 species exerted ≥25% inhibition of proliferation of at least one of the cancer cell lines at 10 μg/mL. In the cases of Brachythecium rutabulum, Encalypta streptocarpa, Climacium dendroides, Neckera besseri, Pleurozium schreberi, and Pseudoleskeella nervosa, more than one extract was active in the antiproliferative assay, whereas the highest activity was observed in the case of Paraleucobryum longifolium. From the tested families, Brachytheciaceae and Amblystegiaceae provided the highest number of antiproliferative extracts. Only 19 samples of 15 taxa showed moderate antibacterial activity, including the most active Plagiomnium cuspidatum, being active on 8 tested strains. Methicillin-resistant Staphylococcus aureus (MRSA) and Staphylococcus aureus were the most susceptible to the assayed species. This is the first report on the bioactivities of these 14 species.

“…[57] These data are in accordance with other reports concerning the chemistry of this liverwort species. [58,59] Shy and Wu [59] divided L. fauriana into three chemotypes: (i) amorphane, (ii) chiloscyphane and (iii) eudesmane. In the essential oil of the Taiwanese L. vitrea the eudesmane-type sesquiterpenoids are the major components: eudesm-4-en-7a-ol (70), eudesm-4(15)-en-7a-ol (71) and eudesm-3-en-7a-ol (72) were identified (Figure 6).…”

A number of liverwort species are known to emit volatile terpenoids and simple aromatic compounds when crushed. The characteristic odour of these spore-forming plants is associated with oil body constituents. Secondary metabolites, which constitute the oil bodies, are also of value for taxonomic investigations. Liverworts have yielded a rich array of secondary metabolites. Many of these compounds are characterized by unique structures, and some of them have not been found in any other plants, fungi, or marine organisms. Gas chromatographic profiling of the volatile extracts obtained from the liverworts has been applied with success in differentiating liverworts species, and also used to resolve the taxonomic problems at genus and family level. Due to the fact that liverworts are morphologically very small and it is difficult to collect a sufficient amount of plant material, there are few research data on the composition of the essential oils obtained from these plants. Nevertheless, the available data indicate that, as in the case of aromatic plants, the components present in essential oils obtained from the liverworts can be used in chemosystematic studies of this plant group. The aim of this paper is to show whether: (i) there are differences in the essential oils composition between different liverwort species; (ii) it is possible to find chemical markers characteristic for the analysed liverwort species; and (iii) the data derived from an analysis of the essential oils are in accordance with the data received from volatile extracts.
