Problems solved by technology

However, as we all know, ethanol is a kind of polar organic solvent, so more alkaline substances with slightly higher polarity are leached in the ethanol medium. astringent
And, use 70% ethanol as extractant macromolecular material dissolution is more, add water and can produce gel phenomenon industrial application is difficult to realize
Furthermore, Geranium purple-backed contains a large amount of red pigment, and the extract obtained by simple organic solvent low-t

Abstract

The invention relates to a gynura bicolor extract for removing free radical in cigarette smoke, which is obtained by the following steps of: soaking dry gynura bicolor with an extractant I and extracting at high pressure; extracting the obtained residue by using an extractant II under ultrasonic twice; combining the three filtrates and carrying out evaporation, condensation and short-path distillation sequentially; and taking the fraction at the light component outlet of a short-path distiller. The extract of the invention can be used as an addition material for removing the free radical in the cigarette smoke.
