Objective: To study the effects of different drying methods on the contents of polysaccharides and mannose in Dendrobium officinale, and to provide scientific basis for the processing methods of Dendrobium officinale.
Methods: Dendrobium officinale was dried by infrared ray, drying, microwave drying equipment and vacuum freezing. The content of polysaccharides was determined by colorimetry and mannose was determined by high performance liquid chromatography. The effects of different drying methods on the content of polysaccharides and mannose were analyzed and compared.
Results: The contents of polysaccharides and mannose in Dendrobium officinale by different drying methods were quite different. The content of polysaccharides and mannose in vacuum freeze-drying samples was the highest, which was significantly better than the other three drying samples (P < 0.05).
