Preparation of Self-emulsifying Preparations of Chinese Medicinal Ingredients Based on Identical Carrier System and Investigation of Their Transdermal Absorption Characteristics in Vitro
To prepare self-emulsifying carrier system which was suitable for three Chinese medicinal ingredients(baicalein
berberine and allicin)
and investigate transdermal absorption effect
in vitro
of these three self-emulsifying preparations.
Method:
2
The optimum formulation and dosage were screened by the saturated solubility method
pseudo-ternary phase diagram method and orthogonal experiment.Transdermal absorption test
in vitro
was carried out with excised rats skin and Franz diffusion cell.The cumulative penetration amounts of baicalein
berberine and allicin in the identical self-emulsifying system were determined by HPLC and compared with baicalein powder
berberine powder and allicin powder
respectively.
Result:
2
The optimum formulation was ethyl oleate-cremophor RH40-polyethylene glycol(PEG)400.The self-emulsifying preparation had a suitable particle size with a relatively regular spherical shape.At 10 h of transdermal absorption
the transdermal rates of baicalein
berberine and allicin in identical self-emulsifying system were 6.898 6
7.600 4
190.040 μg·cm
-2
·h
-1
the cumulative penetration amounts of them were 71.38
85.54
1 795.16 μg·cm
-2
respectively.
Conclusion:
2
The self-emulsifying carrier system is prepared successfully
which can be used by different kinds of Chinese medicinal ingredients
and the transdermal absorption effect
in vitro
of these self-emulsifying preparations is good
which can provide experimental basis for the preparation and transdermal absorption of self-emulsifying preparation of Chinese herbal compound.
