Abstract

Diplazium esculentum (Reytz.) belongs to the family Dryopteridaceae and is an edible fern commonly used by Paniya and Chetti tribes of Western Ghats. Young fronds are stir-fried as a vegetable or used in salads. Wild leafy vegetables remain underutilized due to lack of awareness and promotion of appropriate technologies for their effective utilization. Evaluation of nutritional and anti-nutritional factors of this plant along with multiplication will help to identify a potential source to solve nutrition deficiency problem and also help to maintain biodiversity. Different biochemical parameters like crude fibre, reducing sugar, total carbohydrate, free fatty acids, and proteins were quantitatively estimated using standard estimation methods. Various micronutrients and anti-nutritional factors like phytic acid, trypsins and tannins were also tested. Results showed that this wild leafy vegetable has important nutritional factors. It is rich in micronutrients, beta-carotene, folic acid and minerals such as Ca, Fe and P. Anti-nutritional factors like phytic acids, trypsin and tannins were present but in quite safe quantities. So Diplazium esculentum with rich nutrient factors opens the possibility of the potential utilization of this plant in food or in nutritional/food supplement programmes.
