Paragraph 0046-0048; 0051-0057, (2021/06/23)
The invention relates to a crystal form substance of a plant growth regulator, and a preparation method thereof. The crystal form substance comprises the following cell parameters: alpha = 90 DEG, beta = 90 DEG and gamma = 90 DEG. The preparation method of the crystal form substance comprises the following steps: 1) purifying a crude product of the plant growth regulator to obtain a purified substance; and 2) culturing crystals from the purified product in a mixed solvent. The crystal form substance of the plant growth regulator provided by the invention is a single crystal type compound, and due to the single crystal form, the stability is high, and the bioavailability is more obvious than a polycrystal effect; and the preparation method breaks through the technical bottleneck that technicians in the field cannot obtain the single crystal substance added with the plant growth regulator at the present stage, and the method is simple and easy to obtain.
