Abstract:
Taking 24 Dendrobium officinale and their adultarants from different origins as test materials,the polysaccharides contents of the stems of Dendrobium officinale from one-year-old stem were determined and compared.The results showed that polysaccharide contents of 4 adulterants were below 18.0%，and 17 samples in 20 with the polysaccharide contents above 25.0%，and T4 and T2 had higher content of 47.0% and 44.1%，respectively.D.officinale samples from Yunnan Province were significantly higher than others，with the average polysaccharide content of 40.4%，followed with D. officinale samples from Zhejiang Province (29.0%)，companies in Guangdong Province (28.9%) and D.officinale hybrids (26.9%)，but the polysaccharide contents of D. officinale samples from Guangxi Province was the lowest，only 25.7%.
