Abstract: The present invention relates to flavanoid compounds of general formula (X1) wherein: R1 is selected from a group consisting of morpholinyl, N-methyl piperizinyl, piperidinyl and N,N?-dimethylamino groups, and n ranges from 3 to 6, and process for preparation thereof. The present invention relates to the demonstration of anti Helicobacter pylori activity and gastric antisecretory activity of semisynthetically designed flavonoid compounds, to be used for the prevention and treatment of gastroduodenal disorders in general and peptic ulcer diseases in particular. The present invention also relates to a hetero-dimeric bi-functional molecule that can be used as monotherapy substituting/replacing/overcoming currently used triple/quadruple therapy, thereby implicating/anticipating/envisaging its commercial applicability.

Abstract: The present invention relates to identification of Oroxylum indicum, Indian medicinal plant as a rich source for flavanoid compounds. Mucoprotective and antigastric ulcer properties in the flavone class of compounds isolated therefrom have been identified along with a flavanoids mixture in substantial yields from hexane and acetone extracts. The hexane extract was fractionated, purified and the compounds identified as Oroxylin A, Chrysin and Baicalein. The acetone extract was purified and the compounds obtained identified as methoxy chrysin, Oroxyloside methyl ester and chrysin-7-O-methyl glycoside.

Abstract: The present invention relates to methods of using Oroxylum indicum as a rich source for flavanoid compounds having mucoprotective and antigastric ulcer properties, and containing Oroxylin A, Chrysin and Baicalein.
