There were 20 flavonoids isolated and identified from plants of genus Sambucus, including 8 anthocyanines and 12 other flavonoids. According to Richard Bolli, genus Sambucus worldwide included 9 species, 8 subspecies and 2 variety. Only 2 species and 2 subspecies among them were studied about flavonoid components, so it needs further studies of flavonoids in other plants of genus Sambucus, to find natural sources of antioxydative compounds for prevention and treatment

The study on Holarrhena antidysenterica Wall was carried out in Chi Linh (Hai Duong province) in September 2004. Leaves of Holarrhena antidysenterica Wall were collected, dried, grilled to powder, then extracted and isolated flavonoid. Two flavonoids were isolated, on the base of m.p, UV, IR, MS, 1H-NMR, 13C-NMR, DEPT analyses, they were identified as Kaempferol and Quercetin. This is the first time the flavonoids were reported as a substance isolated from Holarrhena antidysenterica Wall in Vietnam
