Phytochemical Screening and Antioxidant potential of Plagiochasma appendiculatum Lehm. & Lindenb. and Sphagnum fimbriatum Wilson

Abstract

In recent time bryophytes are gaining attention in terms of their unique phytochemistry. They can generate a wide range of bioactive phytochemicals. Though many of the bryophytes have been evaluated for this aspect yet majority of them are unexplored regarding their phytochemistry and bioactive potential. Hence, in present attempt 2 commonly growing species of bryophytes, viz., Plagiochasma appendiculatum (thalloid liverwort) and Sphagnum fimbriatum (moss) were evaluated for their phytochemical profiling using Folin-Ciocalteau and aluminium colorimetric methods. While antioxidant activity of selected species was evaluated by DPPH and NOSA. It was found that these species have higher levels of total phenols and flavonoids and have good antioxidant potential. Further, to check their possible role as antimicrobial agents, the plant extracts were tested against selected fungal and bacterial strains. The results suggested that these 2 bryophyte species have substantial antifungal and antibacterial activities. Based on this study, these plants appear as a good contender to evaluate further for future herbal formulations.

Analysis of the antioxidant activity and caffeine content of Barbula indica (Hook.) Spreng. (Bryophyta; Pottiaceae)

“…Most bryologists in India have so far concentrated studies on morpho-taxonomy and diversification issues (15,16,17). As a result, currently there is a lacuna in research relating to phytochemical constituents of bryophytes in India.…”

Effects of Water–Ethanol Extracts from Four Sphagnum Species on Gene Expression of Selected Enzymes in Normal Human Dermal Fibroblasts and Their Antioxidant Properties

“…Sphagnum magellanicum extract also showed the strongest neutralizing effect on DPPH and ABTS radicals, as well as antioxidant properties measured by the FRAP method, while Sphagnum palustre extract most strongly inhibited lipid oxidation and protein oxidation. The antioxidant properties of Sphagnum extracts determined by the DPPH, ABTS or FRAP methods have already been described [ 11 , 15 , 16 , 17 ]. It is worth noting that this study is the first to compare the inhibition of biomolecules oxidation by extracts from different species of the genus Sphagnum .…”

“…The presence of many primary and secondary metabolites in plants of the Sphagnum genus has prompted in vitro studies investigating the extracts obtained from these plants. Scientific research confirms their antibacterial [ 8 , 11 , 13 , 14 ], antioxidant [ 11 , 15 , 16 , 17 ], cytotoxic [ 8 , 10 ], aromatase inhibiting activity [ 12 ] and protective effects on kidney epithelial cells [ 9 ].…”

Utilization of the First Land Plants (Bryophytes) as a Source of Beneficial Bioactive Chemicals

“…Phytochemical properties: Phytochemicals are naturally occurring in plants. These phytochemicals have a vital role in the protection of plants from diseases as well as in defence mechanisms 18 .…”

“…Liverworts possess the strong antioxidative machinery suggested by recent studies. They have the stamina to survive in extreme climates and stressful conditions 18 . Conducted studies have indicated the potential of a few bryophytes to be used as antioxidants for cosmetic and medicinal purposes 19,20 .…”
