Potential Investigation of In Vitro Antioxidant, Anti-Inflammatory and Anti-Haemolytic Activities from Polar Solvent Extracts of Pterocarpus marsupium
Pterocarpus marsupium is a well known plant in ayurvedic system of medicine. The plant has been found to possess diverse number of biological activities and is thus commercially exploited. In the present study, methanol and aqueous extracts of P.marsupium bark were used to evaluate in vitro antioxidant, anti-inflammatory and anti-haemolytic activities. In vitro antioxidant activity was carried out by DPPH, ABTS, phosphomolybdenum, reducing power assays, anti- inflammatory activity by inhibition of protein denaturation and anti-haemolytic by hyposaline induced haemolysis. Total phenolic and flavonoid content was also estimated. Methanol extract showed an effective pharmacological activity in all assays when compared with their respective standards. The maximum phenolic and flavonoid contents were found to be (280 ±0.47mg/g) and (620±0.81mg/g) respectively in methanol extract of Pterocarpus marsupium. This study indicates the presence of active constituents which can be exploited for the treatment of various diseases and also could be used in pharmaceutical industry.
