ABSTRACT:
.alpha.-L-aspartyl-L-phenylalanine methyl ester II type crystals consisting of two types of crystals, II.sub.A and II.sub.B type, which interconvert from one to the other depending upon the equilibrium moisture content of the crystals, wherein one type of crystal, II.sub.a, exhibits X-ray diffraction peaks at angles of diffraction of at least 20.6.degree., 21.2.degree., 5.0.degree. and 11.1.degree., and the other type of crystal, II.sub.B, exhibits X-ray diffraction peaks at angles of diffraction of at least 15.2.degree., 11.1.degree., 19.6.degree. and 4.5.degree., as measured by X-ray diffractometer using CuK.sub..alpha. radiation and wherein the equilibrium moisture content of either of the crystals at a relative humidity of 78% is not higher than about 3%.
