Abstract
The by-products or residues of agriculture industries have been taken more attention for their valuable source of natural antioxidants in recent decades. In this work, the Taif rose water by-product obtained after hydro-distillation of Taif rose (Rosa damascena trigintipetala Dieck) was investigated for its biological and phytochemical properties. The results showed that the Taif rose water byproduct had free radical scavenging activity toward artificial 1,1-diphenyl picrylhydrazyl (DPPH•) radical with SC50= 23.72±0.36 mg/ml and also had high antioxidant capacity (329.53±18.75 mg ascorbic acid equivalent/g dry extract) and reducing power activity (211.31±2.79 mg ascorbic acid equivalent/g dry extract). Phenolic compounds are the major components and the antioxidant properties were attributed to them. The direct infusion ESI(-ve)-MS analyses of Taif rose water by-product showed the presence of phenolic compounds belonging to hydrolysable tannins and flavonoids. The acute, sub-chronic and chronic toxicity studies of Taif rose water by-product in mice suggested that it was safe and not toxic. From this work, it is obvious that the water by-product obtained after hydro-distillation of Taif rose could be used as a good natural inexpensive source of antioxidant polyphenolics after more phytochemical, in vitro and in vivo studies.
