The invention relates to a gastrodine compound and a pharmaceutical composition thereof. The gastrodine compound is a crystal. The X-ray powder diffraction determines that the characteristic peaks are displayed when 2theta+ / -0.2 degree is 4.5 degrees, 5.7 degrees, 7.9 degrees, 10.3 degrees, 11.2 degrees, 13.0 degrees, 16.4 degrees, 19.6 degrees, 21.2 degrees, 22.7 degrees, 24.8 degrees, 26.7 degrees, 29.6 degrees, 34.1 degrees and 35.3 degrees. The gastrodine compound has very high stability, thereby greatly enhancing the medicine safety. The invention also relates to a pharmaceutical composition preparation containing the gastrodine compound. The composition preparation can be a freeze-dried powder injection, injection, tablet or capsule. The gastrodine freeze-dried powder injection, injection, tablet or capsule preparation provided by the invention has the advantages of simple prescription technique, obviously higher stability, and enhances the medicine safety and effectiveness.
