Effect of Acori Tatarinowii Rhizoma on Intestinal Absorption of Ginsenosides in Dingzhi Xiaowan
To explore the effect of Acori Tatarinowii Rhizoma on intestinal absorption of ginsenosides in Dingzhi Xiaowan
and reveal the mechanism of Acori Tatarinowii Rhizoma acting as " adjuvant drug" in this formula.
Method:
2
The contents of ginsenoside Rg
1
Re and Rb
1
were measured by UPLC-MS/MS and the absorption of three ginsenosides in different intestine segments was investigated by rat single pass intestinal perfusion
in situ
including absorption rate constant(
K
a
) and apparent permeability coefficient(
P
app
). Everted intestinal sac model was used to investigate the absorption dosage of three ginsenosides affected by volatile oil from Acori Tatarinowii Rhizoma and verapamil[Ver
a P-glycoprotein(P-gp) inhibitor].
Result:
2
P
app
values of three ginsenosides were ≤0.191×10
-3
cm·min
-1
in Dingzhi Xiaowan when lack of Acori Tatarinowii Rhizoma.Compared with lack of Acori Tatarinowii Rhizoma in Dingzhi Xiaowan group
the
K
a
and
P
app
values of lack of volatile oil from Acori Tatarinowii Rhizoma in Dingzhi Xiaowan group slightly increased without significant difference in the four intestinal segments
but when the prescription had Acori Tatarinowii Rhizoma
the
K
a
increased by 3.97-8.35 fold and the
P
app
increased by 3.99-8.49 fold.The results of everted intestinal sac test showed that volatile oil of Acori Tatarinowii Rhizoma could significantly promote the intestinal absorption of ginsenoside Rg
1
Re and Rb
1
but there was no dose-dependent.
Conclusion:
2
Volatile oil of Acori Tatarinowii Rhizoma can promote the intestinal absorption of three ginsenosides in Dingzhi Xiaowan
and the mechanism may be related to the inhibiting function on P-gp.
