Tigers Milk mushroom has been used for medicinal purposes by local aborigines to treat asthma breast cancer cough fever and food poisoning. Molecular phylogenetic analysis utilizing RNA polymerase II second largest subunit (RPB2) gene identified the wild Tigers Milk mushrooms collected from the state of Pahang in Malaysia for this study as Lignosus rhinocerus in the order Polyporales. The tuber stipe and pileus of this mushroom were analyzed for their basic nutritional composition (fat protein and carbohydrate) and toxic metal content profile (Cadmium Lead and Mercury). The moisture content of these mushroom parts varied from 32.22 (pileus) “ 46.31 (stipe). The dry matter of the mushrooms contained 2.76 (stipe) “ 6.60 (pileus) proteins 0.21 (pileus) “ 0.30 (tuber) fat 1.76 (stipe) “ 4.38 (tuber) ash and 38.47 (stipe) “ 56.30 (pileus) carbohydrates. The toxic metal content of the mushroom samples ranged from 0.03“0.12 mg/kg for Cd 0.80“1.94 mg/kg for Pb and 0.05“0.10 mg/kg for Hg. The present study demonstrated that L. rhinocerus is a potential source of food due to its high carbohydrate content. In addition the trace levels of toxic metals in this mushroom are within the safe level for consumption.

Abstract

Tigers Milk mushroom has been used for medicinal purposes by local aborigines to treat asthma breast cancer cough fever and food poisoning. Molecular phylogenetic analysis utilizing RNA polymerase II second largest subunit (RPB2) gene identified the wild Tigers Milk mushrooms collected from the state of Pahang in Malaysia for this study as Lignosus rhinocerus in the order Polyporales. The tuber stipe and pileus of this mushroom were analyzed for their basic nutritional composition (fat protein and carbohydrate) and toxic metal content profile (Cadmium Lead and Mercury). The moisture content of these mushroom parts varied from 32.22 (pileus) “ 46.31 (stipe). The dry matter of the mushrooms contained 2.76 (stipe) “ 6.60 (pileus) proteins 0.21 (pileus) “ 0.30 (tuber) fat 1.76 (stipe) “ 4.38 (tuber) ash and 38.47 (stipe) “ 56.30 (pileus) carbohydrates. The toxic metal content of the mushroom samples ranged from 0.03“0.12 mg/kg for Cd 0.80“1.94 mg/kg for Pb and 0.05“0.10 mg/kg for Hg. The present study demonstrated that L. rhinocerus is a potential source of food due to its high carbohydrate content. In addition the trace levels of toxic metals in this mushroom are within the safe level for consumption.
