  Troxerutin with a high content of trihydroxyethylrutoside and process for its preparation

  摘要：

  本发明涉及一种具有高三羟乙基芦丁含量的新型曲沙酮。所述曲沙酮至少含有92重量％的7,3′,4′-三羟乙基芦丁，当通过测量富集曲沙酮粉末倒在100毫升水的烧杯表面后，3.5克富集曲沙酮粉末离开烧杯表面所需的时间，以及当通过测量富集曲沙酮在20℃的稳定温度下以2毫米宽、3毫米高的核心形式放置在水表面时，富集曲沙酮被水润湿所需的时间小于100秒时，具有改善的润湿性和溶解性能。

  The invention concerns novel troxerutin with high trihydroxy-ethyl-rutin content. Said troxerutin has at least 92 wt. % of 7,3′,4′-trihydroxyethyl rutin and a wettability expressed in minutes less than 10 minutes, when said wettability is measured in a test consisting in measuring the time taken by 3.5 g of said enriched troxerutin powder to leave the surface of a beaker containing 100 ml of water, at a stabilised temperature of 20° C., when said enriched troxerutin powder is poured at the surface of the water in said beaker, and a wettability less than 100 seconds when said wettability is measured in a test consisting in measuring the time taken by said enriched troxerutin to be wetted by the water contained in a receptacle, such as a beaker, when said enriched troxerutin has been deposited at the surface of the water, in the form of cores of 2 mm wide and 3 mm high weighing 63 ? 2 mg, at a stabilised temperature of 20° C. Said troxerutin has improved properties of wettability and solubility in water.
