葡/果=0.743,f蔗/果=0.823,f麥/果=0.695。QAMS法的計算結(jié)果與外標兩點法的實測值之間存在顯著性差異,其相對偏差遠遠大于5%。結(jié)論 HPLC-ELSD外標法能夠準確地測定YQFM中4種糖類成分的含量,而在ELSD檢測器上建立的QAMS法準確度不如外標法,其原理與適用范圍需要更進一步的探究。;Objective To establish a quantitative analysis of multi-components with a single-marker (QAMS) method for the determination of four components in Yiqi Fumai Lyophilized Injection (YQFM) and the feasibility of establishing QAMS methods on ELSD was further explored. Methods Fructose was used as the internal reference substance. The relative correlation factors (f) of glucose, sucrose and maltose were calculated and established. The results were compared with those obtained by the external standard method in 25 batches of YQFM. Results Within the linear ranges, the f values of glucose, sucrose and maltose to fructose were 0.743, 0.823, 0.695. The two methods show the significant difference in assay results. Conclusion HPLC-ELSD can precisely determine contents of four carbohydrates in YQFM; meanwhile, the accuracy of QAMS method built on ELSD was inferior to that of external standard method, and the working principle of ELSD and feasible concentration range remain to be further studied."/>
