The applicant has carried out the analysis and determination to the extract of Desmodium sativa, and the specific results are as follows:

The extract of Desmodium sativa is an extract, and it is analyzed with a gas-phase mass spectrometer (Varian3800/2200) produced by U.S. Varian Company. By analyzing the total ion current diagram and comparing the NIST05 spectral library, it is found that the extract of Desmodium sativa mainly contains Several major types of compounds such as esters, alcohols, alkanes, fatty acids, etc. Esters mainly include 2-methyl, 1-(1,1-p-methylethyl)-2-methyl-1,3-propylene glycol propionate, 4-ethoxy-butyric acid methyl ester, 2-Methyl-2-propenoic acid-cyclohexyl ester, ethyl 3-hydroxybutyrate, 2-methoxy-2-methyl, methyl 2-butyrate, ethyl N-formate trans-octadecene- (9)-Ethyl acid ester, butyl dodecyl sulfite, amidoethyl oxalate, etc. These esters can effectively remove the turbidity and miscellaneous gases of cigarettes, improve the internal quality of tobacco sheets, endow tobacco with natural flavors such as floral and fruity aromas, and make the smoke clear, light and elegant. Alcohols mainly include n-pentanol, 3-nitro-2-butanol, 2,3-dimethyl, 5-hexenyl-3-ol, 3-pyrrolidinol, 2,2,4-3 Methyl-3-pentanol, 4-dodecanol, 3-pyrrolidinol, 2,2,4-3 methyl-3-pentanol, etc. These alcohols have a pleasant smell, can give tobacco a fruity aroma, can reduce the pungent smell of tobacco sheets, and make the smoke soft. Saturated fatty acids such as palmitic acid have a fatty and waxy smell, which can change the softness of the smoke. When the proportion of unsaturated fatty acids such as 2-chloroethyl linoleic acid in higher fatty acids is high, it will enhance the irritation of the smoke and make the smoke rough. The pyrolysis products of higher fatty acid esters such as ethyl palmitic acid, methyl oleate, and pentadecylcyclobutyl oxalate can inhibit the irritation, purity and aroma of cigarettes. Acids such as 5-aminovaleric acid, acetylhydroxamic acid, and acrylic acid have no direct effect on the aroma of tobacco, but they can reduce the irritation of smoke, make the taste pure and increase the concentration of smoke. Squalene has the function of absorbing oxygen similar to red blood cells, generates activated squalene oxide, and releases oxygen after being transported to the end cells of the body in the blood circulation, thereby increasing the oxygen utilization ability of body tissues and reducing the discomfort of smoke . Vitamin E acts on cigarette smoke to significantly reduce the content of nitrosamines in the smoke and improve the safety of cigarettes.
