Objectives: Research on extraction, isolation and structural determination of several chemical flavonoids extracted from Centella asiatica (L.) URB. - Apiaceae. Materials and method: Centella asiatica is collected in Phong Dien district - Thua Thien Hue. Extracts isolated by solid-liquid extraction and chromatography coordination. Structure determination based on the physical properties and spectral data. Results: From species Centella asiatica (L.) URB. - Apiaceae collected at Phong Dien, Thua Thien Hue has isolated two pure substances. Based on UV spectrum, IR, MS, NMR identified the compound as Quercetin and Kaempferol.
