Facile Root for Isolation of Rhamnocitrin Sulphate from Tetracera Alnifolia Willd

Rhamnocitrin 3-sulphate has been isolated with one percent yield, from Tetracera alnifolia, a non-cultivated medicinal plant from Congo. Rhamnocitrin 3-sulphate has been isolated after recrystallization of crude dried extract obtained from aqueous decoction of Tetracera leaves and stem. In this paper, Rhamnocitrin 3-sulphate has been easily isolated for the first time from Tetracera alnifolia and the corresponding tri-acetylated compound has been synthetized. Identification, characterisation and structure elucidation have been carried out using TLC, HPLC, UV-VIS, NMR and MS analyses in comparison with those described in the literature
