Abstract:
AIM: To establish a method for detecting the residual solvents in protopanaxdiol. METHODS: Capillary GC with HP-PLOT-Q column (30 m ? 0. 53 mm ? 1. 0 ?m) was used to determine residual in protopanaxdiol. N,N-dimethyl-acetamide as solvent media,FID detector and nitrogen as the carrier gas. RESULTS: There was a good linearity at the experimental concentration (r = 0. 999 96-0. 999 99),the RSD of precision was less than 6. 0 % . The spotting recovery of the 3 residul,including methol,ethyl acetate and n-butanol,was in the range of 98. 2%-102. 2% ,and its’RSD was 1. 1%-2. 4% . CONCLUSION: The method is simple,accurate and of high sensitivity,can be used for the determination of residual solvents in protopanaxdiol.
