Abstract:
Objective To establish a measurement method for the content of five compounds (acteoside, harpagide, harpagoside, angoroside-C, and cinnamic acid) in Scrophularia Radix quantitative analysis multi-components by single-marker (QAMS), and verify the accuracy and feasibility of QAMS in the quality control. Methods Taking harpagide as internal standard substance, the relative correlation factor (RCF) of acteoside, cinnamic acid, harpagoside, and angoroside C was established. And the content of each component in Scrophularia Radix was determined by the above-mentioned RCF. In order to prove the scientificity and feasibility of this method, the results were compared with the external standard method. Results The relative correction factors of acteoside, cinnamic acid, harpagoside, and angoroside-C were 0.068 (RSD = 0.53%), 0.060 (RSD = 0.81%), 0.142 (RSD = 1.17%), 0.197 (RSD = 1.82%). No significant differences were found among the quantitative results of four components in 25 batches of Scrophularia Radix determined by the two methods. Conclusion It is feasible and accurate to evaluate the quality of Scrophularia Radix by QAMS.
