The amount of interstellar Al-26 resulting from an intense mass loss from stars in the asymptotic giant branch (AGB) stage is calculated for different laws of mass loss rate. The best agreement with observation is obtained in the case of an order-of-magnitude increase in the mass loss rate of an AGB star for a luminosity lg(L/L-solar) approximately equal to 4.0. Maximum theoretical ratios of Al-26/Al-27 in stellar atmospheres as a function of initial stellar mass are presented.
