7-pentoxy-naringenin and 7,4'-dipentoxy-naringenin and method for simultaneously obtaining 7-pentoxy-naringenin and 7,4'-dipentoxy-naringenin

摘要

the object of the application is 7 - pentoksynaringenina model 2 and 7,4 '- dipontoksynaringenina model 3.the notification covers way receive these compounds, which is, to the substrate.which is naringenina model 1 the following potassium carbonate k2co3 and pentyl iodide in a mole ratio of at least 1: 1.5: 5, and the minimum amount of organic solventwhat is a reactionary, which protects against light and leaves at 20°c to 28°c for a period of 48 to 70 hours with constant stirring.then an organic solvent is vaporized, the following of a saturated solution of sodium chloride nacl and then lead extraction niemieszającym organic solvent with water.dried anhydrous magnesium sulphate and / or anhydrous sodium sulphate and the solvent vaporized, then the obtained extract is purified on column chromatography.
