Antidiabetic Micro-/Nanoaggregates from Ge-Gen-Qin-Lian-Tang Decoction Increase Absorption of Baicalin and Cellular Antioxidant Activity In Vitro

Table 2

The apparent permeability () and absorption rate of baicalin across Caco-2 cell monolayers.

Sample	Apical side baicalin concentration (μg/mL)	(×10^−6 cm/s)	Absorption rate in 3 h	Absorption level
Pure baicalin	—		~1%	Low
GQD	27.6		35%	Medium
MA	12.9		67%	High
400 g supernatant	14.2		66%	High
MNA	12.8		74%	High
