A simple and rapid method has been developed for the extraction of Fe, Ni, Cr and Mn in drinking water samples with a new reagent, pentamethylene dithiocarbamate, into methyl isobutyl ketone (MIBK) and their subsequent determination by atomic-absorption spectrometry. The extraction has been carried out at a high aqueous: organic phase ratio to achieve a(More)
Methanolic extracts of cap and stipe of commercially obtained mushrooms Agaricus bisporus, Hypsizygus ulmarius, and Calocybe indica were analyzed for their antioxidant activity in different chemical systems including reducing power, free radical scavenging, ferric reducing antioxidant power (FRAP), superoxide scavenging, peroxide scavenging, metal chelating(More)
Methanolic extracts of four cultivated edible mushrooms of Pleurotus spp. namely Pleurotus florida, Pleurotus sajor-caju, Pleurotus cystidiosus and Pleurotus djamor along with the sporeless/low sporing mutants of Pleurotus florida, and Pleurotus sajor-caju were analyzed for their antioxidant activity using different chemical assays. The electrochemical(More)
Twenty isolates of Ganoderma spp. indigenous to India were used in this study. A reverse-phase high-performance liquid chromatography (HPLC) method was used to quantify 2 of the most bioactive triterpenes, ganoderic acid A (GAA) and ganoderic acid B (GAB), among the cultivated Ganoderma spp. The HPLC analysis was performed on an Agilent 1260 Infinity HPLC(More)
