英文摘要：

Dendrobium is a valuable traditional Chinese medicine with nourishing yin and clearing away unhealthy heat, ben- efiting the stomach, promoting the production of body fluid,resisting cancer and other effects. The sources of medicinal Den- drobium are broad,the chemical compositions are complex and it has high medicinal value. With the increase of the demand for this traditional Chinese medicine, the resources declined sharply,which made it to be an endangered species. The chemi- cal composition,pharmacological effects and aspects of genetic research were discussed in order to provide a theoretical basis for reasonable protection and sustainable utilization of medicinal Dendrobium.
