The SiTian project, with its vast field of view, will become an ideal platform for scientific research on asteroids. In this study, we develop a pipeline to analyze the photometry of asteroids and derive their periods from the data collected by the SiTian pathfinder project Mini-SiTian (MST). The pipeline is applied to the MST f02 region, an MST test region with a sky area of 2°.29 × 1°.53. Rotation periods of 22 asteroids are derived by the obtained light curve analysis. Among them, there are eight asteroids available in the Asteroid Lightcurve Photometry Database (ALCDEF), and six of them with more photometric points (>200) that have similar period parameters as the ones in ALCDEF. Additionally, the periods for 14 of these asteroids are newly obtained and are not listed in ALCDEF. This study demonstrates the feasibility of asteroid photometric research by the SiTian project. It shows that future observations from the SiTian project will provide even more photometry of asteroids, significantly increasing the number of available light curves. The potential vast photometric data on asteroids will help us to further understand the physics of asteroids, their material composition,and the formation and evolution of the solar system.
