| Abstract: | Capillary gas chromatography method wit sidual organic solvents alcohol, ethyl acetate and meth PEG-20M capillary column is used. The results show that a h FID detector for the determination of reanol in sodium aescinate is presented. A good linear correlation for the three solvents are obtained over the range of 0. 010 1～0. 100 9 mg/mL , 0. 009 9～0. 099 9 mg/mL and 0.006 1 ～0. 060 6 mg/mL, respectively. The correlative coefficients of the three solvents are over 0. 999. The method is easily operative and accurate for precise determination. |
