Abstract
Abstract A study was designed to identify stains derived from plant pigments. Using high performance liquid chromatography (HPLC), 13 species of common weeds were examined, and 12 flavonoids were detected from as low as 100 to 200 μg of dried leaves and from their stains. Identification of plant species could be made, based on the various chromatographic patterns of the flavonoids with different retention indices, using rutin and rhamnetin as the reference standards. A brief practical case of application is described.
