摘要（英）：

The invention relates to a levobupivacaine hydrochloride crystal form A and a preparation method thereof. The levobupivacaine hydrochloride crystal form A is characterized in that a reflection angle 2 theta of an X-ray powder diffraction pattern is in the ranges of 9.6-9.8, 10.6-10.8, 12.5-12.7, 13.3-13.5, 18.9-19.1 and 21.5-21.7, and the peak intensity is 100% when the reflection angle 2 theta is equal to 9.6-9.8. The crystal form is high in purity, high in yield and stable, and the preparation process is simple and easy to implement.
