Rosa indica symbol of godness and beauty known for various healing power, has astringent, sedative, anti-inflammatory and antidepressant qualities. Standard methods were used for qualitative detection of phyto-compounds, and quantitative detection of antioxidants was done using DPPH radical scavenging assay, total phenolics and total flavonoids content were expressed in mg GAE/g dry weight and mg QE/g dry weight. Results revealed phyto-compounds presence in all varieties under study however maximum % inhibition was observed by R. indica var pink perfume (94 +/- 0.6) with IC50 value 0.3376 +/- 0.01mg/mL. Highest phenolic and flavonoid content was observed in the leaves extract of R. indica var cardinal red, i.e. 3.3553 +/- 0.11 (ethanol) mg of Gallic acid equivalents (GAE)/g dry weight and 3.736 +/- 0.001(ethanol) mg of quercetin equivalents (QE)/g dry weight, respectively, at conc. 0.125mg/mL. Our finding provides evidence that all varieties of rose contain medicinally important bioactive compounds and justifies their use for treatment of different diseases. [GRAPHICS] .
