Dendrobium,orchid,is a traditional Chinese herb medicine applied extensively as tonic and precious food for thousands of years recorded in ancient Chinese medical book “Shen Nong\'s Materia Medica”.It\'s well known that bioactivities are usually related to the ingredients\' basis.Based on the previous research,Dendrobium species contain amino acid,sesquiterpenoids,alkaloids and polysaccharides.As the bioactive substances,carbohydrate shows extensive activities in antitumor,antiglycation,immune-enhancing,antivirus,antioxidant,antitumor and etc.Therefore,as the main biologically active substance,the exact structures and latent activities of polysaccharides from Dendrobium species are widely focused on.In this review,we focus on the advancements of extraction methods and diversity of structures and bioactivities of polysaccharides obtained from Dendrobium species.
