Exploration on Determination and Quantity Transfer of Index Components in Benchmark Samples of Erdongtang
To establish the determination for index components in benchmark samples of Erdongtang, and clarify the content and transfer rate rages of index components in 15 batches of benchmark samples, and to explore the quantity transfer of index components of decoction pieces to benchmark samples.
Method
2
Fifteen batches of benchmark samples were prepared, the contents of mangiferin, baicalin and glycyrrhizic acid were determined by high performance liquid chromatography (HPLC)-diode array detector (DAD), the mobile phase was acetonitrile (A)-0.1% formic acid aqueous solution (B) for gradient elution (0-10 min, 10%-17%A; 10-25 min, 17%-19%A; 25-28 min, 19%-25%A; 28-45 min, 25%-33%A; 45-46 min, 33%-45%A; 46-60 min, 45%-55%A), detection wavelength was set at 254 nm. Contents of timosaponin BⅡ and the sum of protoneodioscin and protodioscin were determined by HPLC-evaporative light scattering detector (ELSD), the mobile phase was acetonitrile (A)-water (B) for gradient elution (0-20 min, 24%A; 20-25 min, 24%-27%A; 25-33 min, 27%-28%A; 33-36 min, 28%-90%A; 36-41 min, 90%-24%A).
Result
2
The methodological verification of the established method was good, which could be used for determination of five index components in benchmark samples. The content ranges of mangiferin, baicalin, glycyrrhizic acid, timosaponin BⅡ, and the sum of protoneodioscin and protodioscin in 15 batches of benchmark samples of Erdongtang were 0.14%-0.23%, 2.40%-3.37%, 0.07%-0.44%, 0.43%-0.95%, and 0.15%-0.47%, the transfer rate ranges of them were 33.90%-52.15%, 84.46%-105.61%, 22.59%-93.86%, 38.07%-61.43%, and 53.28%-96.11%, respectively.
Conclusion
2
The consistencies of transfer rate of mangiferin, baicalin, timosaponin BⅡ and the sum of protoneodioscin and protodioscin (except glycyrrhizic acid) between decoction pieces and benchmark samples of Erdongtang are good, indicates that the transfer rates of 4 index components are stable during the preparation process of benchmark samples, which can provide data support for research and development of the compound preparation of this formula.
