Abstract
Diplazium esculentum is one of the very well-liked edible ferns, a common pteridophyte. Very few reports are published about the plant from India. Pteridophytes are acquainted for their biological and medicinal properties for long time but very fewevidences are seen about wetland pteridophytes. The present work focuses on assessment of nutritional relevance of D. esculentum collected from Alappuzha District of Kerala in India, by qualitative phytochemical and overall protein profiling. Chloroform and methanolic extracts of leaves of D. esculentum are used for both assays. The results showed the presence of vital phytoconstituents on qualitative analyses that included Alkaloids, Saponins, Flavonoids, Steroids, Phenols, Cardiac glycosides and Carbohydrates. On protein profiling by Sodium Dodecyl Sulphate Poly Acrylamide Gel Electrophoresis (SDS PAGE), 5 distinct bands corresponding to molecular weights ~250 kDa, ~130 kDa, ~100 KDa, ~55 KDa and ~15 KDa which showed nutritional importance of the fern, Diplazium esculentum. The future perspectives of study may include the quantitative estimation of phytoconstituents and proteins that paves the way for the incredible health benefits of the fern for humans.
