Evaluation of free-radical quenching properties of standard Ayurvedic formulation Vayasthapana Rasayana

Abstract: BackgroundCellular damage induced by free-radicals like Reactive Oxygen and Nitrogen Species (ROS and RNS) has been implicated in several disorders and diseases, including ageing. Hence naturally occurring anti-oxidant rich-herbs play a vital role in combating these conditions. The present study was carried out to investigate the in vitro free-radical quenching capacity of a known Ayurvedic poly-herbal formulation called Vayasthapana Rasayana.MethodsMethanol extracts of Vayasthapana Rasayana formulation (VRF) … Show more

“…A linear correlation between DPPH scavenging activity and temperature variation showed a statistically significant correlation (R 2 = 0.8963) with natural (vitamin C; R 2 = 0.9691) and synthetic antioxidant (BHT; 0.8877). These data are in accordance with earlier research (Park et al 2009;Mukherjee et al 2011;Salar & Seasotiya 2011), suggesting that a high temperature does not influence antioxidant activity in K. alvarezii.…”
