“…These properties of the ferns d. linearis and P. aquilinum have constituted them to cause acaricidal property, which would be the first report against O. coffeae. The adult mortality is due to interference with ecdysteroid metabolism and inhibition of ecdysis triggering hormones (ETH) (Hincapie et al 2011) and by their intrinsic chemical constituents. These variations in metabolites of P. aquilinium, d. linearis, and C. interruptus caused considerable acute toxicity in O. coffeae.…”

Prabhakaran P., Radhakrishnan B., Srikumar K.K., Suresh Kumar B. (2017): Efficacy of certain common ferns against red spider mite Oligonychus coffeae and tea mosquito bug Helopeltis theivora infesting tea. Plant Protect Sci., 53: 232-242.In search for botanicals as an alternative remedy to synthetic chemicals in the pest control of tea plantations, ferns such as adiantum raddianum, asplenium aethiopicum, Cyclosorus interruptus, dicranopteris linearis, diplazium polypodioides, and Pteridium aquilinum were evaluated against the two major pests of tea, red spider mite Oligonychus coffeae Nietner and tea mosquito bug Helopeltis theivora Waterhouse, which are the foremost seasonal pests in tea fields, causing severe crop loss. Apart from synthetic chemicals, only the neem kernel extract is recommended in tea fields. The aqueous extracts of ferns were screened at different concentrations against these pests under laboratory and field conditions. The extracts of P. aquilinum and d. linearis showed good contact toxicity at a 5% concentration to O. coffeae. The acaricidal activity was observed in the order P. aquilinum > d. linearis > C. interruptus > a. raddianum > d. polypodioides > a. aethiopicum. Under field conditions, the extract of d. linearis and P. aquilinum showed a 50% reduction in the population of red spider mite and caused no phytotoxic effect to tea leaves. But their insecticidal activity was less pronounced against H. theivora. They exhibit antifeedant activity, which was sustained only for 24 hours. The photochemical screening of extracts showed a qualitatively increased level of saponins in P. aquilinum, d. linearis, and C. interruptus. The study shows that the aqueous extracts of d. linearis and P. aquilinum can be incorporated in the mite control programme in tea.Keywords: botanicals; aqueous extracts; acaricidal activity; insecticidal activity Tea occupies a major position among various plantation crops. It is grown in 50 different countries and the prime producers are India,

“…Blechnum L. is a genus of ferns chemically characterized by the presence of flavonols, hydroxycinnamic acids, lignans and phytoecdysones, compounds with recognized central nervous system properties. Plants of this group have been investigated for a wide range of biological activity, including anti‐inflammatory and antinociceptive, antioxidant, anticancer, antibacterial and wound healing effects .…”

“…Most of the secondary metabolites reported in B. chilense, B. hastatum, B. magellanicum and B. penna-marina species are grouped in phenolic compounds and organic acids that have also been reported in species such as B. orientale, B. novae-zelandiae, B. occidentale and B. binervatum [ 32 , 33 , 34 , 35 , 36 ]. In the four study species, the compounds neophytadiene, phytol (3,7,11,15-tetramethyl-2-hexadecen-1-ol), isophytol (3,7,11,15-tetramethyl-1-hexadecen-3-ol), ecdysone, 2-deoxyecdysone (2-deoxycrusteecdysone), ponasterone, shidasterone and β-sitosterol (stigmast-5-en-3-ol) have also been reported [ 35 , 37 , 38 , 39 , 40 ]. Flavonoid-like compounds present in species of the genus Blechnum are also shared by species of the genera Pteris and Pteridium of the family Pteridaceae [ 41 ].…”

The genus Blechnum represents one of the most ecologically and therapeutically important groups of ferns that grow in tropical, subtropical and temperate regions. In this work, the chemical fingerprint of lyophilized extracts of Blechnum chilense, B. hastatum, B. magellanicum and B. penna-marina species, the determination of their antioxidant activity through ORAC, FRAP and DPPH assays and inhibition of cholinesterase enzymes (AChE and BChE), and an in silico analysis of selected majority compounds on cholinesterase enzymes were identified. Nineteen compounds were recorded for B. chilense, nine in B. hastatum, seventeen in B. magellanicum and seventeen in B. penna-marina by liquid chromatography coupled with quadrupole-time-of-flight mass spectrometry (UHPLC-ESI-QTOF-MS). The content of phenolic compounds, flavonoids, antioxidant activity and enzyme inhibition were variable among species, with best results for B. penna-marina. Molecular docking evidenced low toxicities, significant pharmacokinetic properties, and significant binding affinities of the tested compounds for the AChE and BChE enzymes. These fern species show high diversity of bioactive compounds and represent a promising resource in phytotherapy, especially for their optimal levels of phenolic compounds that support their antioxidant activity.
