New spectroscopic components in the visual binaries ADS 4200 (HD 37013AB = BD+21o902AB = HIP 26328; 7.2 - 7.8 mag; F7d - F6d; B - V = 0.501 mag; epoch 2000: 5h36m25s +22deg01') and ADS 12656 (HD 185082 = HU 679 = IDS 19324+5024 = BD+50o2819; V = 8.3 mag; B - V = 0.552 mag; epoch 2000: 19h35m03s +50deg38') are studied. ADS 4200A and ADS 12656A are single-lined spectroscopic binaries with orbital periods of 49.384 +/- 0.023 days and 39.618 +/- 0.004 days, respectively. The radial-velocity curves are constructed, and the spectroscopic orbital elements are computed. The dynamical parallax is estimated.
