  We construct explicitly the grade star Hermitian adjoint representation of
osp(2/1; C) graded Lie algebra. Its proper Lie subalgebra, the even part of the
graded Lie algebra osp(2/1; C), is given by su(2) compact Lie algebra. The
Baker-Campbell-Hausdorff formula is considered and reality conditions for the
Grassman-odd transformation parameters, which multiply the pair of odd
generators of the graded Lie algebra, are clarified.
