Phase degeneration occured during the solution of crystal structure of asosarmen-tosin by using symbolic addition procedure. This led to an E-map containing simultaneously both enantiomorphs. By making use of the component relation, this E-map has successfully been retrieved leading to an E-map containing only one of the enantiomorphs. It turns out that, with the help of component relation there is no need to modify the starting set even though phase degeneration occurs during the solution of noncentrosymmetric crystal structures by symbolic addition method. Hence the efficiency of the symbolic addition procedure can be improved.
