The invention relates to a novel amoxicillin compound, and belongs to the technical field of medicines. According to the novel amoxicillin compound, characteristic peaks are displayed at positions, with angle 2theta being 5.47+/-0.1 degrees, 7.08+/-0.1 degrees, 10.03+/-0.1 degrees, 17.91+/-0.1 degrees and 23.62+/-0.1 degrees, in an X-ray powder diffraction spectrum obtained through Cu-Ka ray measurement, and a heat absorption peak exists at the position, with temperature being 245-250 DEG C, of a differential scanning amount heat spectrum. The novel amoxicillin compound is high in flowability, can better meet the requirements of medicine pharmaceutics, and is better suitable for preparing various pharmaceutic preparations. Capsules prepared from the novel amoxicillin compound are high in stability, and therefore medicine use safety and effectiveness are improved, and the incidence rate of adverse reaction is avoided.
