Chemical analysis of a wild edible mushroom: Pleurotus djamor (Rumph. ex Fr.) Boedijn.

Abstract

The aim of the present study was to determine the proximate composition, mineral contents and identification of organic compounds in Pleurotus djamor (Rumph. ex Fr.) Boedijn., a wild edible mushroom species from the tropical forest bed of Tripura, North-East India. Proximate values of ash, moisture, crude protein, crude fibre, crude fat and carbohydrates contents were measured. C, H and N were analysed using CHN analyzer. Moreover, analysis for metals was carried out using the Atomic Absorption Spectrometry (AAS). Furthermore, crude extract of P. djamor were evaluated for organic compounds using Gas Chromatography-Mass Spectrometry (GC-MS). For proximate values, moisture percentage was the highest, followed by carbohydrate, fibre, protein, ash and fat. Among CHN, carbon was the highest followed by hydrogen and nitrogen. AAS showed potassium having the highest concentration; then iron; lead had the lowest value of all the eleven elements analyzed. Seven compounds have been identified with the help of GC-MS analysis depending on the peaks. The results indicate that P. djamor could be an important source for mineral and as regard to proximate composition and the active compounds detected using GC-MS could possibly exhibit potential biological activity.
