%X In this paper,we study the Hojman conserved quantity of Lie symmetry for mechanical systems with variable mass in phase space under a general infinitesimal transformation. The determining equations and Hojman conservation theorem of Lie symmetry of the system in phase space are obtained. An example is given to illustrate the application of the result.
