“…However, other components, such as flavonoids, di-and triterpenoids, polyketides and lignanes, were isolated from ferns, 7 possibly contributing to the plants' bioactivity. The fern Pteridium aquilinum containing the natural product pterosin, was reported to exhibit smooth muscle relaxant properties.…”

“…1 Since ancient times there has been strong interest in the application of ferns for their traditional medicinal properties [2][3][4] and in Central American countries ferns are traded in the local markets for medicinal uses. 5 While the chemical composition of primary and secondary metabolites in ferns have been examined, [6][7][8] few reports have characterized the volatile components from aromatic ferns. 9 The genus Anemia Sw. (Anemiaceae) contains over 100 species of aromatic ferns that are utilized in popular medicine, 10 with the great majority found in the warmer and drier regions of America from Texas to Argentina.…”

The essential oil composition of the aerial parts of Anemia tomentosa var. anthriscifolia (Anemiaceae) was characterized by GC-MS. Total volatile oil yield extracted by steam distillation was 0.2% dry weight basis. The volatile oil was composed mainly of sesquiterpenes (75%, as the relative percentage of the total essential oil) with lower amounts of monoterpenes (15%); no phenylpropanoids were detected. The sesquiterpenes were composed mainly of oxygenated components (67%), including α α α α α-bisabolol (51%), spathulenol (1%), caryophyllene oxide (3%), α α α α α-bisaboloxide (1%) and 14-hydroxy-9-epi-(E)-caryophyllene (1%). The monoterpenes were dominated by neral (5%) and geranial (7%), with lower amounts of α α α α α-pinene, camphene, 6-methyl-5-hepten-2-one, 1,8-cineole and pinocarveol. This is the first report of the essential oil accumulation (0.2%) and volatile composition in the aromatic fern A. tomentosa.

“…For instance, Psilotaceae contain mainly amentoflavone along with its monomer apigenin (Wallace and Markham, ; Cambie, ). Biflavonoids are very rare in other ferns, as they have so far only been found in Osmundaceae and Cyatheaeceae (Gottlieb et al ., ). Most Ophioglossaceae contain mainly flavonols (Gottlieb et al ., ; Warashina et al ., ), but Helminthostachys zeylanica (L.) Hook.…”

“…Some of the alkaloids, namely huperzin A, are promising in terms of their anti‐cholinergic and antiinflammatory activity (Wang and Tang, ; Ma and Gang, ). Lycopodiaceae and Isoëtaceae also contain anticancer flavones such as apigenin, chrysoeriol, luteolin and tricin, as well as their O ‐glycosylated or C ‐glycosylated forms (Cambie, ; Gottlieb et al ., ; Markham and Moore, ). Lycopodiaceae are a source of diterpeneoids and triterpeneoids (Tsuda et al ., ; Gottlieb et al ., ) and phenolic acids (Pedersen and Ollgaard, ) etc.…”

Ferns and Lycopods—A Potential Treasury of Anticancer Agents but Also a Carcinogenic Hazard

Many species of seedless vascular plants-ferns and lycopods-have been used as food and folk medicine since ancient times. Some of them have become the focus of intensive research concerning their anticancer properties. Studies on the anticancer effect of crude extracts are being increasingly replaced by bioactivity-guided fractionation, as well as detailed assessment of the mechanism of action. Numerous compounds-especially flavonoids such as amentoflavone and protoapigenone, and also simpler phenolic compounds, steroids, alkaloids and terpenoids-were isolated and found to be cytotoxic, particularly pro-apoptotic, or to induce cell cycle arrest in cancer cell lines in vitro. In in vivo experiments, some fern-derived compounds inhibited tumour growth with little toxicity. On the other hand, many ferns-not only the well-known Bracken (Pteridium)-may pose a significant hazard to human health due to the fact that they contain carcinogenic sesquiterpenoids and their analogues. The objective of this review is to summarise the recent state of research on the anticancer properties of ferns and lycopods, with a focus on their characteristic bioactive constituents. The carcinogenic hazard posed by ferns is also mentioned.
