Total phenolics, flavonoids and antioxidant properties of three Ceropegia species from Western Ghats of India

A comprehensive analysis of three Ceropegia species from the Western Ghats reveals significant antioxidant properties, with total phenolic content (TPC) and total flavonoid content (TFC) varying widely among extracts. The study identifies gallic acid, vanillin, cathechol, and ferulic acid as major phenolic compounds, all demonstrating strong DPPH radical scavenging activity, ferric reducing antioxidant power (FRAP), and metal chelating ability. These findings correlate significantly with TPC and TFC, underscoring the potential of these species for natural antioxidant applications. This research represents the first detailed investigation into the phenolic profile and antioxidant properties of Ceropegia spp., providing valuable insights for both scientific and practical purposes.
