Main chemical compositions and fingerprints of Tiepishihu (Dendrobium candidum) produced from different areas
摘要
Abstract
Objective To compare the quality of Tiepishihu (Dendrobium candidum) produced from different areas in Yunnan Province, and provide evidence for selecting its optimal producing area. Methods The hot-dip method, ultraviolet spectrophotometry and HPLC were applied to determine the content of alcohol extracts, polysaccharide and mannose in Tiepishihu and at the same time, HPLC gradient elution was used to establish fingerprint system, which then was given cluster analysis. Results Tiepishihu produced from different areas in Yunnan Province had difference in the content of main chemical compositions. The content of alcohol extracts (13.65% ) and polysaccharide (35.87% ) was the highest in Tiepishihu produced from Menghai. The content of mannose was the highest (24.%% ) in Tiepishihu produced from Dehong and was secondary highest (24.01%) in Tiepishihu produced from Menghai. The content of effective compositions was the lowest in Tiepishihu produced from Honghe. The similarity of HPLC fingerprints of Tiepishihu produced from different areas was higher (between 0.883 and 0.987), while the similarity was the lowest (0.883) between Tiepishihu produced from Menghai and control fingerprint, and that among other Tiepishihu products were all higher than 0.950. The cluster analysis on the total area of HPLC fingerprint common peaks of Tiepishihu produced from 6 areas showed that these 6 areas could be divided into two categories, one included Menghai and Wenshan, and other one included Simao, Dehong, Honghe and Yuxi, Conclusion Tiepishihu produced from different areas in Yunnan Province has difference in quality, and that produced from Menghai is the best.关键词
