Abstract

The invention discloses an iris tectorum extract. A preparation method comprises the steps that 1, fresh iris tectorum leaves are smashed and soaked by using deionized water, and a soaking solution and soaking residues are obtained after soaking; 2, glyceryl triacetate is used for extracting the soaking solution, and the soaking solution is decompressed and concentrated to obtain a solution A; 3,the soaking residues are soaked in complex enzyme hydrolysate with cellulase, pectinase, citric acid, vitamin C, acetic acid and water, an enzymolysis solution and enzymolysis residues are obtained after soaking, and the enzymolysis solution is decompressed and concentrated to obtain a solution B; 4, the enzymolysis residues are subjected to microwave auxiliary extraction, an extracting agent is an ethanol solution of malic acid or potassium sorbate, solid-liquid separation is conducted after extraction, and a collection solution is decompressed and concentrated to obtain a solution C; 5, thesolution A, the solution B and the solution C are mixed to obtain the iris tectorum extract. The content of heavy metal Pb and Cd and the content of tar in smoke which is released by cigarettes whichare prepared by cut tobacco with the iris tectorum extract in the normal burning process are remarkably lowered compared with those in smoke which is released by cigarettes without the iris tectorum extract, the perniciousness is reduced, and the beneficial effect is remarkable.

Description

technical field [0001] The invention belongs to the technical field of tobacco additives, in particular to an iris extract and its application in cigarettes. Background technique [0002] Iris is a perennial herb widely distributed in China. Iris root is a plant of the family Iridaceae (Iris Iris tectorum), bitter, sweet, cold in nature. Growing around forests, wet watersides and hilly areas facing the sun. Iris has anti-inflammatory properties and has significant curative effects on asthma and throat diseases. As a traditional Chinese medicine, orris root contains flavonoids, volatile oils, saponins, and tannins. [0003] The microwave extraction process is realized by high-frequency electromagnetic waves penetrating the medium and directly reaching the inside of the plant material. Microwave radiation can be converted into heat energy to heat rapidly, so that the internal temperature of the cell rises rapidly, and a large amount of water inside the cell evaporates, the...
