Zusammenfassung:New nateglinide crystals - i.e. nateglinide P type crystals having the following powder X-ray diffraction peaks: 4.8°, 5.3°, 14.3°, 15.2° (2¸) can be producede by dissolving nateglinide in a mixed solvent composed of a solvent in which nateglinide is highly soluble and another solvent in which it is difficultly soluble, adding another solvent in which nateglinide is difficultly soluble to the obtained nateglinide solution and isolating the obtained crystals.
