The present invention relates to a tanshinone precusor liposome spherical powdery preparation. At first, the film dispersion method is used to prepare tanshinone liposome suspension, then it is spray-dried under certain condition, by regulating the spray drying condition to control the shape appearance of dried particles. The obtained tanshinone precusor liposome powdery preparation possesses good spherical appearance and fluidity, it not only can raise the bioulility of tanshinone, but also can solve the problem of stability during storage of tanshinone liposome. |
