Garcinia imberti Bourd. a critically endangered tree belongs to the family Clusiaceae found only in India. The phytochemicals and antioxidant studies were carried out for the methanolic extracts of Garcinia imberti leaves and stem bark using DPPH and ABTS radical scavenging assay. Preliminary phytochemical screening of methanolic extracts of Garcinia imberti revealed the presence of various bioactive components like alkaloids, flavanoids, steroids, glycosides, phenols, saponins, terpenoids, resins, carbohydrates and tannins in both leaves and stem bark. The quantitative analysis of phytochemicals of the extracts showed the presence of high amount of tannins (0.92 ± 0.23mg/gm) and alkaloids (0.83 ± 0.48mg/gm) in leaf and high concentration of flavanoids (0.65±0.16mg/gm) and tannins (0.78±1.12mg/gm) in bark extract. The result of the present study concluded that the methanolic extracts of Garcinia imberti leaves and stem bark possess antioxidant activity due to the presence of significant amount of phenolic compounds which are the major contributors of antioxidant activity. The finding of this study suggests that the studied plant is a potential source of natural antioxidant that could have great importance as therapeutic agents in preventing or slowing the progress of oxidative stress related degenerative diseases.
