title: Flavonoid and methoxyellagic acid sodium sulphates from Frankenia laevis L.
abstract: Two new flavonol di-sodium sulphates and an ellagic acid methyl ether mono-sodium sulphate have been found in the aqueous alcohol whole plant extract of Frankenia laevis L. They have been identified as the 3,7-di-sodium sulphate of kaempferol, the 3,7-di-sodium sulphates of quercetin and the 4'-mono-sodium sulphate of ellagic acid-3-methyl ether. Also, five known compounds have been isolated and characterized from the same extract. Establishment of all structures has been achieved mainly, by ESI-MS and NMR.
