The present invention relates to the methods for preparing synthetic guggulphospholipids, their fatty acid analogues and other bioactiv molecules. The present invention relates to E-guggulsterone and Z- guggulsterone or mixture of E- and Z-guggulsterones. The present invention also provides a novel method for the preparation of E-guggulsterol and Z- guggulsterol or mixture of E-and Z-guggulsterols from a mixture of E- and Z- guggulsterones. The present invention further relates to guggulphospholipids and other bioactive molecules incorporated into complexes such as liposomes, complexes, emulsions, vesicles, micelles, and mixed micelles, which can include othe active agents, such as hydrophobic or hydrophilic drugs for use, e.g., in treatment of human and animal diseases.
