Pharmacodynamic screening and simulation study of anti-hypoxia active fraction of xiangdan injection.

BACKGROUND

The herbal formula Xiangdan injection and its modifications have been used in traditional Chinese medicine for about hundreds years to alleviate pain and promoting blood.

OBJECTIVE

To investigate the anti-hypoxia active fraction of Xiangdan injection.

METHODS

Xiangdan injection was extracted by ligarine, chloroform, acetic ether, n-butanol and water, represented respectively by A, B, C, D and E. Five extractions were group on the L12(2(5)) orthogonal designed table. NIH mices anti-hypoxia experiment under normal pressure with rats was adopted on the basis of orthogonal design, prediction pharmacodynamics model of TCM prescriptions was established, and the simulation bias was evaluated by combining two scatterplots. The anti-hypoxia active fraction of Xiangdan injection was determined by experiments.

RESULTS

The prediction model of TCM prescriptions established in this study can predict the drug actions for different formulas, and PE%

CONCLUSIONS

As indicated in model prediction and experimental confirmation, the pharmacodynamic actions of the 5 formulas are all superior to that of the original formula, and ADE has the best effect.
