Methods The free monosaccharide in Dendrobium officinale Kimuraet Migo samples was removed by ultrasonic extraction method instead of soxhlet extraction, and the mannose in samples was extracted by microwave method instead of dew decoction method. There was no derivative reaction and internal standard method in this method. The sample extract was filtered by microporous filtering film, then analyzed by the high performance liquid chromatography (HPLC) described in harmacopoeia, and the content of mannose was determined by external standard method. Results There was a good linear relationship between the mannose content which ranged from 0.054~0.648 mg/ml and peak area with the correlation coefficient (r) greater than 0.999. The average recoveries of mannose at 3 different adding levels were 97.66%, 98.10% and 98.68%, respectively. Conclusion This method is simple, accurate, precise, and greatly shorten the processing time, which can be used to the content determination of mannose in Dendrobium officinale Kimuraet Migo.
