The present invention relates to 7-carboxymethyloxy-3′, 4′, 5-trimethoxy flavone.monohydrate which is a non hygroscopic product suitable for the preparation of metered dose of 7-carboxymethyloxy-3′, 4′, 5-trimethoxy flavone having protective activity for gastrointestinal tract including the colon, and a preparation method and uses thereof. 7-carboxymethyloxy-3′, 4′, 5-trimethoxy flavone.monohydrate of the present invention has advantages such as mucus protecting activity for gastrointestinal tract including the colon, convenience for handling and storage under ordinary humidity owing to its non-hygroscopicity, and ability to contain an active compound consistently for the formulation production of a medicine. In addition, the preparation method of 7-carboxymethyloxy-3′, 4′, 5-trimethoxy flavone.monohydrate of the present invention reduces long steps of total synthesis and requires mild conditions for the production of a compound because autoclave condition is not necessary for methylation in this case, and makes mass-production possible without any purification process such as recrystallization or column chromatography.
本发明涉及一种7-羧甲氧基-3'、4'、5-三甲氧基黄酮一水合物,该一水合物是一种非吸湿性产品,适用于制备具有保护胃肠道包括结肠的活性的7-羧甲氧基-3'、4'、5-三甲氧基黄酮的计量剂量,并提供其制备方法和用途。本发明的7-羧甲氧基-3'、4'、5-三甲氧基黄酮一水合物具有以下优点:对胃肠道包括结肠的粘液保护活性,便于处理和在普通湿度下储存,因其非吸湿性;并且能够稳定地包含活性化合物,以便制剂生产药物。此外,本发明的7-羧甲氧基-3'、4'、5-三甲氧基黄酮一水合物的制备方法减少了总合成的长步骤,并且由于在这种情况下不需要高压灭菌条件进行甲基化,因此需要较温和的条件来生产化合物,并且可以进行大规模生产,而无需任何纯化过程,如重结晶或柱层析。
