Phytochemical screening,antioxidant activity,total phenolic and total flavonoid contents of seven local varieties of Rosa indica L.

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 ± 0.01 mg/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. 0.125 mg/mL. Our finding provides evidence that all varieties of rose contain medicinally important bioactive compounds and justifies their use for treatment of different diseases.
