Abstract: Insulin and Leptin resistance are the hallmarks for the development of type 2 diabetes mellitus (T2DM) and obesity. Both of these conditions are associated with increased activity and idiom of Protein Tyrosine Phosphatase 1B (PTP 1B). Therefore, inhibition of PTP 1B activity or down-regulation of its expression has become a striking area of therapeutics development in order to ameliorate the phenomenon of Insulin and Leptin resistance. Lack of awareness and late diagnosis makes diabetes difficult to manage. PTP 1B inhibitory activity by Erythroxylum monogynum plant extracts in the cytosolic supernatant of goat skeletal muscle and the liver was estimated. Erythroxylum monogynum plant extraction was done in hydroalcoholic solution (water–ethanol 20:80 (v/v)) and Methanol. The Polyphenols and protein content were identified in the hydroalcoholic and methanolic extracts. The greatest PTP 1B inhibitory activity in goat liver and skeletal muscle was found in the hydroalcoholic extract. Erythroxylum monogynum is a potent natural source of PTP 1B inhibition and may become cost-effective therapeutics in correcting metabolic disturbances of T2DM, obesity and cardiovascular disorders.
