METHOD FOR EXTRACTING FLAVONOL GLYCOSIDES FROM AGANONERION POLYMORPHUM PIERRE EX SPIRE (AGANONERION POLYMORPHUM PIERRE EX SPIRE)

Abstract

The invention proposes a method for extracting Aavonol glycoside compounds from the leaves of Aganonerion polymorphum pierre cx spire (Aganonerion polymorphum pierre cx spire) belonging to the Apocynaceae family. In which the Aavonol glycoside compound is selected from a group including curcucomoside with formula (1) and nicotilin with formula (2): And in that method, the steps are as described in the patent. The compounds in the patent inhibit NO production in RAW 264.7 cells activated by lipopolysaccharide (LPS). The patent not only creates a link for the proper use of the *Lá giang* plant but also guides further in-depth research on this plant, a valuable food and medicinal plant of Vietnam that needs investment in research to become an important source of raw materials in the preparation and development of pharmaceuticals with preventive and therapeutic effects on inflammatory diseases.
