    摘要: 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.
