A process for the preparation of pharmaceutically acceptable salts of chiral Amlodipine namely S(−) Amlodipine and R(+) Amlodipine from without isolation of a free base from with optical purity rank between 96-99% is described in the present invention. The process comprises resolving RS amlodipine base using of L(+) or D(−) tartaric acid to obtain salt of corresponding to the acid used in ee rang from 96-99%.
