Iron, manganese, zinc and copper in dark plum were determined by ICP-AES with microwave digestion. Under optimum conditions, the recoveries were in the rang of 102%-105%. The RSD is less than 4.0%. The method is simple, rapid and accurate.
To analyze the monosaccharides composition and their molar ratio in Fuctus mume polysaccharide and Ligustrum japonica tea polysaccharide by using acetylation derivatization and capillary gas chromatography.The monosaccharides composition and their molar ratio of the Fuctus mume polysaccharide are: rhamnose:arabinose:xylose:mannose:glucose:galactose=0.65:4.96:0.93:1:7.03:8.61;the monosaccharides composition and their molar ratio of the Ligustrum japonica tea polysaccharide are: rhamnose:arabinose: xylose: mannose:glucose:galactose =1:3.31: 0.24:0.58:2.96:5.70.The method was established with the relative standard deviations and the recoveries being in the range of 0.37%～0.91% and 95.9 %～102.3 %,respectively.
