Table 1.

Apparent permeability coefficients (P_app) values of standards, S. baicalensis radix extract, and binary mixtures.

	Papp(× 10−6 cm s−1)
	Baicalin	Baicalein	Wogonin
Standard	0.02 ± 0.01	91.56 ± 2.72	57.23 ± 5.42
SBE	n.d.	116.58 ± 3.97	134.43 ± 3.59
SBE/Cs 80:500	n.d.	119.05 ± 7.64	133.66 ± 6.44
SBE/Cs 80:1000	n.d.	129.03 ± 1.34	130.60 ± 3.58

Compounds with P_app < 0.1 × 10⁻⁶ cm s⁻¹ = low-permeable compound, those with P_app ≥ 1 × 10⁻⁶ cm s⁻¹ = high-permeable compounds indicated values are means (±SD, n = 3); n.d.—not detected in the acceptor.
