Abstract:Fifteen compounds were isolated and elucidated from the alcohol extract of Fallopia cynanchoides by modern phytochemical isolation and spectroscopic methods, and these compounds can be divided into four sterols, a phenol, anthraquinones, a chromone, two stilbenes and three flavonoids. All of these compounds were obtained from this plant for the first time. Chemotaxonomic studies indicated that F. cynanchoides has very close relationships with F. convolvulus and F. aubertii, and the genus Fallopia may have close relationships with the genera Rheum, Fagopyrum, Reynoutria and Polygonum.
Keywords:Chemical constituents  Chemotaxonomic study  Polygonaceae
