“…Phenolic compounds present in bracken fern, such as the flavonoids quercetin and kaempferol, showcase antioxidant properties, suggesting potential health benefits [48,61,62]. P. aquilinum encompasses various nutritional components, including carbohydrates, proteins, dietary fiber, vitamins, and minerals [63]. Although the nutritional composition may fluctuate based on factors such as plant maturity and environmental conditions, bracken ferns typically harbor significant quantities of dietary fiber, vitamin C, vitamin A, vitamin B complex, potassium, and manganese [64].…”

Bracken fern (Pteridium aquilinum (L.) Kuhn) is ubiquitous and acts as a cosmopolitan weed in pastures and similar environments. Despite its historical uses, it presents risks due to toxicity. This study, conducted in the second half of 2023, aimed to assess the environmental and health hazards of P. aquilinum, primarily focusing on its carcinogenic compound, ptaquiloside. The literature was comprehensively reviewed using diverse databases, including PubMed, Web of Science, Scopus, and Google Scholar. Information was synthesized from original research articles, meta-analyses, systematic reviews, and relevant animal studies. Animals grazing on bracken fern face annual production losses due to toxin exposure. The substantial impact on biodiversity, animal health, and human well-being arises from the presence of ptaquiloside and related compounds in milk, meat, and water, along with the increasing global prevalence of P. aquilinum and its swift colonization in acidic soil and fire-damaged areas. The objectives were to identify major bioactive compounds and explore their effects at molecular, cellular, pathological, and population levels. Various cooking techniques were considered to mitigate toxin exposure, although complete elimination remains unattainable. Therefore, the findings emphasize the need for cautious consumption. In conclusion, continued research is necessary to better understand and manage its environmental and health implications.

“…Ferns have been consumed as food in many countries for centuries [ 1 ]. As rich sources of protein, fiber, minerals, vitamins, essential amino acids, and fatty acids, ferns provide important nutrients to humans [ 2 ]. Furthermore, ferns have a high content of secondary metabolites that comprise saccharides, phenolics, polyketides, and terpenoids [ 3 ], whose pharmacological activities as diuretics, analgesics, and anti-inflammatories in cases of cystitis, dermatitis, and common cold, and as emmenagogues, have been extensively reported [ 4 , 5 , 6 , 7 ].…”

Bracken fern (Pteridium aquilinum var. latiusculum (Desv.) Underw. ex A. Heller) has long been grown industrially in South Korea. Conventional propagation methods, including planting rhizomes and in vitro seedling culture, are labor intensive and expensive, and thus not commercially suitable. We aimed to develop a system to produce synthetic seeds using fern spores (SFS). Synthetic seeds were prepared by mixing bracken spores and alginate matrix. Spore germination and gametophyte and sporophyte growth and development from SFS proceeded normally. Spore density affected gametophyte and sporophyte numbers. SFS prepared using cold (4 °C) long-term storage spores (even 7-year-old spores) could effectively form sporophytes. The highest germination was observed at 25 °C. Soaking-treated SFS successfully formed sporophytes, even after 30 days of storage at 4 °C; indeed, sporophytes formed even after five days of storage at 25 °C during transport conditions. SFS were sown in plug trays for commercial use. Young sporophytes grown from plug seedlings were greenhouse cultivated, and transplanting within eight weeks was effective for root growth and growing-point formation. Developing synthetic seeds is a feasible solution for facilitating efficient transport and the handling of small-sized fern spores; furthermore, this SFS technology provides the basis for fern seedling culture and fern spore industrialization.

“…About 25% of these ferns are found in a humid region or in tropical montane areas in Indonesia (Karger et al 2014;Kusmana and Hikmat 2015). Thoroughly screening of plant-derived extracts as a part of drug discovery program showed that ferns have interesting biological properties such as anti-inflammatory, antibacterial, antiviral, antitumor hepatoprotective, cytotoxic, antihyperglycemic, antinociceptive, and immunomodulatory activities (Greeshma and Sridhar 2019;Hendra et al 2019;Ho et al 2010).…”

Abstract. Faizal A, Taufik I, Rchman AF, Azar AWP. 2020. Short Communication: Antioxidant and antibacterial properties of tree fern Cyathea contaminans. Biodiversitas 21: 2201-2205. Cyathea contaminans (Wall. ex Hook) Copel is a tree fern used in traditional practices as herbal remedies to treat different kinds of diseases. To explore its further medicinal uses, we designed a study to determine the antioxidant and antibacterial activities of polar and non-polar extracts of this fern. The fern leaves (mature fronds), young fronds, and hairs were collected from Tangkuban Perahu Nature Park, West Java, Indonesia, and were extracted by methanol 80% or n-hexane. Antioxidant activity was evaluated by DPPH (1,1-diphenyl-2-picrylhydrazyl) assay, whereas antibacterial activity was measured by growth inhibition of Escherichia coli and Staphylococcus aureus. Results showed that methanol extract from mature leaves (fronds) exhibits weak to very strong antioxidant activities (IC50 37.13-225.19 µg/mL), whilst hairs and young fronds showed weak activities, i.e. IC50 179.50-255.49 µg/mL and IC50 544.27->2000 µg/mL, respectively. Hexane fraction from fronds was active against E. coli and S. aureus (43.92% and 46.8%), and from hairs against E. coli (48.1%) in concentration of 250 µg/mL. Gas Chromatography-Mass Spectrometry (GC-MS) analysis indicated that active compounds from fronds extract were dominated by 2H-tetrazole, 5-(thiophen-2yl) methyl (14,29 %), 2-thiophene acetic acid, 2-methyl phenyl ester (14,54%), and phenol, 2,6-bis(1,1-dimethyl ethyl)-4-methyl (10.54%). This study concluded that mature leaves (fronds) of C. contaminans is the potential to be used as antioxidant and antibacterial agents.
