The purpose of this research was to determine the most important soil factors affecting the active ingredients of Capparis spinosa L. For this purpose, five main habitats were identified in the northern rangelands of West Azerbaijan province, and sampling was conducted at representative points within each habitat. Vegetation sampling was performed using a systematic random method in 40 plots of 2 × 2 meters (4 m²), spaced 20 meters apart along four 200-meter transects. To collect soil data, each transect was divided into three sections (initial, middle, and end), and soil samples were taken from the surface horizon (0–30 cm) with three replications. Variables such as electrical conductivity, pH, lime percentage, organic carbon percentage, clay percentage, silt percentage, sand percentage, bulk density, organic matter, and mineral elements (nitrogen, phosphorus, potassium, magnesium, calcium, and calcium carbonate) were measured in the laboratory. After shade drying, the plant samples were transferred to the laboratory to measure phenol content, total flavonoids, and antioxidant activity. The results showed significant differences among the studied habitats in terms of total phenol content, flavonoid content, and antioxidant activity. The most important soil factors affecting the total phenol, flavonoid, and antioxidant performance of Capparis spinosa were pH (0.8847), calcium (-0.7361), calcium carbonate (0.6052), clay percentage (0.5185), and sand percentage (0.6441). Therefore, considering the adaptability of Capparis spinosa to such habitat conditions, its relatively favorable density, and fruit production, it is suggested that preserving, restoring, and developing this species in rangelands and agricultural fields, as well as its domestication, can enhance pasture productivity, increase rangeland users' income, and boost the gross production of natural fields.
