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-temperature preheating extraction must be red. If it is added to cigarettes, it will obviously affect the appearance of cigarettes and bring smokers unnecessary mental burden
On the other hand, since cigarettes are a special product that has high requirements on vision and taste, especially the taste, the extract of G. argentina obtained by the extraction method described in the above article is not suitable for adding to cigarettes to remove smoke. Medium free radical

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.

Description

technical field [0001] The present invention relates to a preparation containing free radical scavenging from organic components of geranium purpura, in particular to a preparation for scavenging free radicals in cigarette smoke. Background technique [0002] Begonia f im bristipula Hance (Begonia f im bristipula Hance) is a Begonia plant in the family Begoniaceae, also known as red cabbage, blood-enriching vegetable (Taiwan), fungus, blood-skin vegetable, water notoginseng, blood-skin vegetable, purple-backed geranium, Amaranthus, red amaranth, red amaranth, red cabbage, angelica, red jade, purple back vegetable, red back notoginseng, Guanyin vegetable, leaf under red, red back vegetable, red winter maple, red wind vegetable and Guanyin Amaranth etc. Purple-backed geranium is a semi-cultivated species with tender stems and leaves used as vegetables.
