The mushroom is a significant source of nutrition for rural tribal populations in Manipur. This study examines the nutritional profile and antioxidant activity of three wild edible mushrooms consumed by these populations. The mushrooms were found to have high protein and vitamin C content, with Ramaria thindii J470 exhibiting the highest antioxidant activity.
The mushroom is an important food for the rural tribal populations in Manipur, because of its high nutritional contents. In this study, we report on the nutritional profile of three wild edible mushrooms consumed by the tribal populations of Manipur viz.: Macrocybe gigantea J124; Lactifluus leptomerus J201 and Ramaria thindii J470. The studied mushrooms possess a high protein content of 37.6%, 20.8% and 16.4%, respectively. They have a high vitamin C content with low vitamin B1, B2 and folic acid. Among the three mushrooms, M. gigantea J124 possesses the highest mineral content, followed by R. thindii J470 and L. leptomerus J201. The total phenolic content of L. leptomerus J201, M. gigantea J124 and R. thindii J470 were 26.206, 29.23 and 30.99 mg GAE/g, with flavonoid content of 6.646, 6.854 and 9.187 mg quercetin/g, respectively. R. thindii J470 has the highest TPC and TFC content, which correlates with its DPPH radical scavenging activity. The IC50 values for R. thindii J470, M. gigantea J124 and L. leptomerus J201 are 242.0 mu g/mL, 550.4 mu g/mL and 689.0 mu g/mL, respectively, which suggest that the higher content of phenolic compounds in R. thindii J470 contributes to its radical scavenging properties.
