In this work, Taxithelium napalense ethanolic extract and its fractions were evaluated for the antidiabetic activity in rat based on phytochemical and free radical scavenging properties. The ethanolic extract, fraction IV and V significantly attenuated the blood glucose levels at 600, 200 and 200 mg/kg with 50.0, 33.5 and 42.0% inhibition respectively. The histopathological studies were manifesting the recuperation of damaged cells in liver and pancreas tissues. The outcomes of the present work affirm that the T. napalense has a potency to plummet the overproduction of free radicals and blood glucose levels in the diabetic-induced rat.
Tatipamula et al.: GC-MS analysis of Taxithelium napalense Considering the antidiabetic potentiality of the moss Taxithelium napalense, the present study was undertaken to explore the chemical constituents that are present in this species. The entire moss Taxithelium napalense was extracted by ethanol and the extract obtained was subjected to gas chromatography-mass spectrometry. Sixty nine compounds were identifi ed, which are reported for the fi rst time from this species. From the gas chromatography-mass spectrometry analysis, it was determined that the octadecanoic acid methyl ester was the chief component present in Taxithelium napalense. In addition, the total phenolic and fl avonoid contents of ethanol extract of Taxithelium napalense were found to be 101.43±0.38 mg Q/g and 229.73±3.07 mg GA/g, respectively. Additionally, the IC 50 of the ethanol extract of Taxithelium napalense on α-glucosidase was found to be 34.5 μg/ml, while acarbose value was 29.5 μg/ml. This is the fi rst report on the chemical investigation of the moss Taxithelium napalense.
