Propolis is an organic substance that considered a biostimulant agent and plays a vital role in increasing bioactive compounds content in plants. The study investigated the properties of two different kinds of propolis i.e., Egyptian and Chinese propolis. The physical and chemical analyses results of the Egyptian propolis showed that it contain 253.703 mgGAE/g total phenolic compound, 76.766 mgQE/g total flavonoid compound and 5.417 g/100g total alkaloid. Also, the effect of five concentrations of aqueous extract of the Egyptian propolis was studied as a foliar spray on tomato plants, which were (1, 2, 10, 20, 100 mg propolis ml-1). Tomato plants treated with propolis (100 mg/ml) showed a significant effect in antioxidant content and other bioactive compounds compared to control plants.
