Four flavonoids from Echinosophora koreensis and their effects on alcohol metabolizing enzymes.

24 Jun 2009 A new prenylated dihydroflavonol, 3-hydroxy-kenusanone B 1, as well as three other known isoflavanones, sophoronol 2, sophoraisoflavanone A 3 and kenusanone H 4, were isolated from the rhizomes of Echinosophora koreensis. The structures of these ... Read more...

Antioxidant properties of isolated isorhamnetin from the sea buckthorn marc.

30 May 2009 In the present study, the process of separation and purification of isohamnetin from marc of sea buckthorn was obtained. The antioxidant properties of the pure isolated isorhamnetin were evaluated by the scavenging of the diphenylpicrylhydrazyl ... Read more...

Flavonol tetraglycosides from fruits of Styphnolobium japonicum (Leguminosae) and the authentication of Fructus Sophorae and Flos Sophorae.

13 May 2009 The dried fruits and seeds of Styphnolobium japonicum (L.) Schott (syn. Sophora japonica L.) are used in traditional Chinese medicine and known as Fructus Sophorae or Huai Jiao. The major flavonoids in these fruits and seeds were studied by LC-MS ... Read more...
