Abstract:
Objective To study the protein binding rates ofgardenioside,paeoniflorin and naringin in Weiyanling granules in bovine serum albumin,rat plasma and human plasma.Methods The equilibrium dialysis method was carried to determine the binding-rates of three components in Weiyanling granules in bovine serum albumin,rat plasma and human plasma.The HPLC method was used to determine the mass concentration of three components in weiyanling granules in inner and outer dialysis and to calculate the plasma protein-binding rates.Results The linear relationship,precision,extraction recovery and stability of gardenoside,paeoniflorin and naringin all conformed to the methodological requirements.Within the low,middle and high concentration (5.084,10.04 and 20.08 g/L) of Weiyanling granules,the protein-binding rates of gardenioside and bovine serum albumin were 23.77％ ± 13.39％,10.75％ ± 1.34％,5.82％ ± 6.53％,respectively;the protein-binding rates of paeoniflorin were 51.81％ ± 6.53％,30.12％ ± 6.61％,21.39％ ± 9.45％,respectively;the protein-binding rates of naringin were 70.21％ ± 3.31％,67.61％ ± 1.31％,56.00％ ± 3.46％,respectively;the protein-binding rates of gardenioside and rat plasma were 71.56％ ± 3.00 ％,43.56％ ± 12.22％,40.63％ ± 4.73％,respectively;the protein-binding rates ofpaeoniflorin and rat plasma were 55.72％ ± 1.60％,47.59％ ± 6.33％,40.07％ ± 0.72％,respectively;the protein-binding rates of naringin and rat plasma were 85.85％ ± 3.53％,85.38％ ± 0.99％,79.99％ ± 2.57％,respectively;the protein-binding rates of gardenioside and human plasma were 13.56％ ± 2.40％,3.02％ ± 2.41％,5.82％ ± 2.08％,respectively;the protein-binding rates of paeoniflorin and human plasma were 9.49％ ± 5.23％,5.01％ ± 1.10％,3.98％ ± 1.54％,respectively;the protein-binding rates of naringin and human plasma were 25.04％ ± 2.61％,26.09％ ± 13.82％,20.20％ ± 2.24％,respectively.Conclusions Within 5.084,10.04 and 20.08 g/L,the protein binding-rate of gardenioside,paeoniflorin and naringin were shown asfollow,rat plasma ＞bovine serum albumin ＞ human plasma.There were significant differences in species.
