Abstract:
OBJECTIVE:To study the contents changes of polysaccharide and 5-HMF in Polygonati rhizoma from different pro-ducing areas after different processing,and provide reference for the development of processing technology of Polygonati rhizoma from different producing areas and the quality standard of different processing products. METHODS:UV spectrophotometry and HPLC were conducted to respectively determine the contents of polysaccharide and 5-HMF,and compare the content differences of polysaccharide and 5-HMF in Polygonati rhizoma from different producing areas [Shaanxi Lueyang County,Shaanxi Huangling County,Yunnan Fumin County (genuine producing areas),Shaanxi Taibai County] by fresh-cutting,dry-cutting,steaming and steaming with wine. RESULTS:Polysaccharide of sample from Yunnan Fumin County showed the highest content in fresh-cut sam-ples(13.4%),no 5-HMF(0)was detected;polysaccharide contents were respectively 10.8%-13.4%,8.9%-10.8%,5.5%-6.9%, 5.6%-6.5% after fresh-cut,dry-cut,steamed and steamed with wine,5-HMF contents were 0,0,0.21%-0.50%,0.25%-0.72%. Compared with no processing samples (fresh-cut),polysaccharide contents in Polygonati rhizoma were decreased in turn after dry-cut,steamed and steamed with wine,5-HMF contents were increased in turn after steamed and steamed with wine. CONCLU-SIONS:It is suggested to consider origin factor in developing processing technology of Polygonati rhizoma from genuine and non-genuine producing areas. 5-HMF content determination index should be added into quality standard of processing products after steamed and steamed with wine.
