Pharmacodynamic Material Basis of Sanqing Jiangtang Decoction[J]. Chinese journal of experimental traditional medical formulae, 2013, 19(9): 267-270. DOI: 10.11653/syfj2013090267.
Objective: To evaluate the inhibitory activity of Sanqing Jiangtang decoction and chemical constituents on alpha glucosidase enzyme and to exploit the bioactive constituents. Method: The samples were prepared by macroporous adsorptive resins(JT-1-JT-13). Glucose oxidase method and starch tolerance test experiments were adopted to evaluate the inhibitory activity of Sanqing Jiangtang decoction and its different separated fractions. Result: It was found that fractions(JT-1
JT-3
JT-6
JT-7)
separated from Sanqing Jiangtang decoction
mainly contributed to the inhibitory activity. JT-7 showed the most significant activities in the experiments. Conclusion: Glycosides and alkaloid may be the principle effective substance in the active fraction.
