Introduction: Paneer-boot, with its antifungal and antibacterial effects, blood sugar and cholesterol-lowering, immune system, and antioxidant activity, has recently received pharmacologists' attention due to its high compatibility. Due to difficult ecological conditions, it can grow in the country's tropical regions such as Sistan and Baluchestan Province .
Materials & Methods: This study was designed in a completely randomized design with four replications under laboratory conditions at Khorasan Razavi Agricultural and Natural Resources Research and Education Center. Concentrations of 0, 2, 4, 6, 8, and 10 bar PEG were used to induce the effect of drought stress on MS medium containing BAP on secondary traits of cheese .
Results: The results showed that the drought stress significantly increased antioxidant enzymes such as catalase, peroxidase, ascorbate peroxidase, proline, phenol, and flavonoid content membrane leakage. On the other hand, it resulted in a significant decrease in the relative humidity content, potassium ion content and potassium to sodium ratio. Also, most of the studied traits had a significant correlation. Conclusion: The results showed that the Paneer-boot plant had acceptable tolerance to induction of drought stress with polyethylene glycol. Enzymatic and non-enzymatic mechanisms had a significant role in reducing the adverse effects of drought stress. On the other hand, drought stress increased some metabolites, such as phenol and flavonoids, which have medicinal uses .

Backgrounds Quinoa (Quino Chenopodium.Willd ) is attended due to its high nutritional value recently. Nutrients of Quinoa including amino acids ,antioxidant compounds ,essential fatty acids, minerals and vitamins led to research on the characteristics of this plant. While few studies have been done in Iran on characteristics of Quinoa.Materials and Methods To assess the nutraceutical potential of quinoa, the antioxidant capacity of quinoa leaves and seeds was investigated. The antioxidant activity against DPPH radicals is highly depends on the phenolic content of samples. In this research, using high performance liquid chromatography (HPLC), the ingredients of seed and leaf extracts were separated and identified. In addition, its antioxidant properties were measured by the evaluation of DPPH free radical scavenging and were used to measure the content of phenolic compounds by Follin-Ciocalteu method.Results Total phenol content in the seeds and leaves extract of quinoa, 54.4 and 76.3 (mg gallic acid per gram of extract) respectively and flavonoids in extracts of quinoa seeds and leaves 26.3 and 36.7 (mg quercetin per gram of extract) respectively were obtained. Analysis of variance showed that the concentration of synthetic antioxidant have significant effect on DPPH free radical scavenging (P
