Investigation into the anti-thrombosis effect and contents of total saponins and flavonoids in the bioactive fraction of Naodesheng prescription.

ETHNOPHARMACOLOGICAL RELEVANCE: Naodesheng prescription is a widely used traditional Chinese medicine (TCM), and mainly applied in clinics to treat cerebral arteriosclerosis, ischemic stroke, sequelae of cerebral hemorrhage etc.

AIM OF THE STUDY: The present study was designed to investigate the anti-thrombosis effects of this prescription, and to search its bioactive fraction.

MATERIALS AND

METHODS

We evaluated the anti-thrombotic effects by measuring platelet aggregation in rats, and the clotting time and protection rate in mice. The contents of total saponins and flavonoids in the bioactive fraction were determined by UV-vis spectrophotometry.

RESULTS

The results showed that Naodesheng has significant anti-thrombotic and anticoagulation effects. The contents of total saponins and flavonoids in the bioactive fraction were 7.885% and 8.434%, respectively.

CONCLUSIONS

Such study will contribute to further exploration of Naodesheng in the therapy of thrombosis diseases and to its re-development based on the bioactive fraction and ingredients.
