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 .

Objectives In recent years, researchers tried to find new compounds with herbal origins to treat and prevent diseases. The current study aimed at investigating the antioxidant and anti-inflammatory effects of Melilotus officinalis and Fraxinus excelsior alcoholic extracts, commonly used in traditional medicines. Methods After preparing the ethanolic extracts of M. officinalis and F. excelsior by the maceration method, the antioxidant properties were investigated by the cupric ion reducing assay (cupric assay) and the anti-inflammatory effects were also investigated through the prevention test of bovine serum albumin (BSA) and its transformation potential.Results The obtained results showed that both mentioned plants had antioxidant and anti-inflammatory effects. The antioxidant properties changed based on the concentration of extracts, and antioxidant and anti-inflammatory properties increased along with the concentration increase. The highest amount of phenolic compound in F. excelsior was 0.04 mg/g of dry extract; this plant also showed the highest antioxidant effect (0.714±0.045). The highest amount of flavonoid compounds in M. officinalis was 9.23 mg; this plant showed the highest anti-inflammatory effects (0.21±0.033 ). Conclusion The employed screening methods were useful to find biological components with different properties.
