Objective: To observe inhibition of Qiaojing Bushen capsules(QJBS) in vitro on glucose absorptionin small intestinal. Method : SD rats were fasted and gave water for 24 hours

then sacrificed to prepare small intestine in vitro everted model. Rats were divided into the blank control group

and acarbose tablets group 0.25 g·L-1 and QJBS group: QJBS 1-QJBS 5(2.5

5.0

10.0

20.0

40.0 g·L-1). The sugar substrate and tested drugs were added into gut sac

which were incubated for 120 min at 37 ℃ to determin glucose concentrations

and the inhibition rate was calculated. Result: Each group of QJBS can inhibit small intestinal absorption of glucose

when the drug concentration was 20 g·L-1

inhibitory effect was the most obvious. The inhibition rat was (67.7±10.5)%

which was equal to acarbose. Conclusion: QJBS can inhibit intestinal glucose absorption

the effect may be related to inhibition of intestinal α-glucosidase.
