INTRODUCTION “Linh chi” - the Vietnamese name for Ganoderma can be used in the prevention and treatment of various types of disease. Various compounds have been isolated from the fruiting bodies, spores, gills, and mycelia of many Ganoderma mushrooms. Ganoderma contains many bioactive natural components, including triterpenes, steroid, polysaccharides, proteins, and unsaturated fatty acids [1-5]. It has been identified as new potent lead structures for the development of novel pharmaceuticals against infectious diseases, cancer, and other diseases. The majority of biological activities are its immunomodulatory and antitumor activities [1–8]. The majority of triterpenes and steroid of Ganoderma exhibit a wide range of biological activities, including antitumor, .
