- Abstract: OBJECTIVE: To compare the polysaccharide contents of Dendrobium officinale in collection periods. METHODS: The contents of polysaccharide and mannose were determined by phenol-sulfuric acid method and HPLC. The ratio of peak area between mannose and glucose was worked out by HPLC. RESULTS: The polysaccharide content of Dendrobium officinale distributed from 26.52% to 46.78%, the mannose content was between 13.36% and 25.25%, and the ratio of peak area between mannose and glucose was 2.48-5.91. CONCLUSION: The polysaccharide contents of Dendrobii officinalis from different sources were diverse, all of which accorded with the standard of Chinese Pharmacopoeia: The content of polysaccharide in Dendrobium officinale from Yunnan province exceeded that from Zhejiang province, and the mannose content in biennial samples were higher than annual samples.
