[Abstract]
Objective The HPLC fingerprint and the content determination method of the benchmark sample of Gegen Qinlian Decoction (葛根芩连汤, GQD) were established to study the rule of quantitative transmitting of GQD benchmark sample. Methods Fifteen batches of GQD benchmark samples were prepared according to the record method of “Treatise on Febrile Diseases”, and the HPLC fingerprint of 15 batches of benchmark samples was established. The peak attribution and similarity range in the fingerprint were clarified, and the quality transfer indexes such as the range of extract yield, the content range of index components and the range of transfer rate were analyzed. The quality control system of GQD benchmark samples was preliminarily established. Results A total of 34 common peaks were calibrated for 15 batches of GQD, and the similarity was good (> 0.99). The contents of puerarin, daidzin, daidzein, baicalin, wogonoside, baicalein, wogonin, berberine hydrochloride, palmatine, liquiritin, glycyrrhizic acid in the benchmark sample were 0.803 1%—1.093 8%, 0.104 8%—0.178 9%, 0.011 7%—0.024 4%, 0.470 9%—0.736 9%, 0.211 2%—0.219 9%, 0.001 1%—0.002 2%, 0.001 2%—0.002 2%, 0.053 2%—0.115 4%, 0.022 4%—0.042 3%, 0.118 8%—0.195 4%, 0.087 6%—0.099 2%, respectively. The average transfer rates of decoction pieces to decoction and decoction to benchmark samples were 17.71%—19.69% and 84.18%—104.00% for puerarin, 10.32%—13.65% and 86.90%—105.38% for daidzein, 21.13%—27.65% and 64.64%—104.09% for daidzein, 22.46%—23.99% and 71.58%—107.61% for baicalin, and 21.38%—28.16% and 82.54%—106.78% for wogonoside, 2.15%—3.81% and 51.85%—83.33% for baicalein, 4.83%—9.55% and 43.75%—73.33% for wogonin, 6.33%—8.70% and 60.33%—99.95% for berberine hydrochloride, 11.09%—15.79% and 60.56%—76.94% for palmatine, 57.82%—76.53% and 80.98%—103.70% liquiritin, 14.98%—18.08% and 87.96%—106.12% for glycyrrhizic acid, respectively. The average dry paste rate transfer rate of 15 batches of benchmark samples was 81.35%. Conclusion Through the combination of fingerprint, extract yield and index component content determination, the quality transfer process of the benchmark sample of the classic prescription GQD was analyzed, which can provide reference for the quality control research of the classic prescription preparation of GQD.
