We present here the Akn 120 Hβ line profiles from 97 spectra observed from 1977 till 1990 at Crimean Astrophysical Observatory (Appendix 1). The Hβ line has been fitted with three broad and one narrow Gaussian throughout the whole considered period. The central broad components of the Hβ and a shelf cause the Hβ line shape variation. Three broad Gaussians may suggest the existence of three broad line regions in the central part of the Akn 120. Long-term Hβ line shape variations in spectra of this galaxy are discussed
