Hemiterpene Glycosides with Anti-platelet Aggregation Activities from Ilex Pubescens

Summary

This serves for the purpose of improving mini-circulation, lower blood pressure, inhibit platelet aggregation, prevent thrombus, reduce cardiac ischemia, decline the excitation of the cardiac conduction system and enhance the ability of anoxia resistance of body. Two hitherto unreported novel hemiterpene glycosides were isolated in substantially pure form from the root of Ilex pubescens known as “Mao-Dong-Qing”. The chemical structures and some properties of these hemiterpenes have been elucidated. These hemiterpene glycosides possess anti-platelet aggregation activity more potent than those of salvianolic acid B and aspirin and may be used in pharmaceutical compositions in humans and mammals in need of such treatment.

Technology Benefits

Improve mini-circulation, lower blood pressure, inhibit platelet aggregation, prevent thrombus, reduce cardiac ischemia, decline the excitation of the cardiac conduction system and enhance the ability of anoxia resistance of body

Technology Application

Treat cardiovascular diseases and hypercholestaemia, improve mini-circulation, lower blood pressure, inhibit platelet aggregation, prevent thrombus, reduce cardiac ischemia, decline the excitation of the cardiac conduction system and enhance the ability of anoxia resistance of body

Detailed Technology Description

Two hitherto unreported novel hemiterpene glycosides were isolated in substantially pure form from the root of Ilex pubescens. The chemical structure and some properties of these hemiterpene glycosides have been elucidated and are named pubescenoside A and pubescenoside B by the inventors. These hemiterpene glycosides possess anti-platelet aggregation activity more potent than those of salvianolic acid B and aspirin and may be used either alone or in combination in pharmaceutical compositions in humans and mammals in need of such treatment.
