example 1
[0019] Take 50g of fresh upper and middle sesame leaves, add them to 250mL boiling water, boil for 0.5 hours, remove the sesame leaves, put them into 250mL×2 cold water, rinse them twice, remove them, squeeze them dry, and dry them in the sun to obtain dried sesame leaves; Take out the cooking liquid, filter, rinse the filter residue twice with a small amount of the first rinse, and pour the rinse into the first rinse. The filtrate was distilled and concentrated to viscous under normal pressure to obtain natural tobacco smoke free radical scavenger Ⅰ.
example 2
[0021] Take 50g of fresh lower sesame leaves, add them to 250mL of 70% ethanol, heat and reflux for 0.5 hours, remove the sesame leaves, then use 250 mL×2 of 70% ethanol to extract twice under the same conditions, remove them, squeeze them dry, and the residue Discarded; combined three times of extracts, vacuum distillation concentrated to viscous, natural tobacco smoke free radical scavenger II.
example 3
[0023] Take 100g of fresh lower sesame leaves, bake at 105°C for 1.5 hours, crush them, pass through a 100-200 mesh sieve, add 500 mL of a mixture of water, ethanol and 1,2-propylene glycol to the obtained powder, water, ethanol and 1, The mass fractions of 2-propanediol were 45%, 50% and 5%, respectively, stirred evenly, heated in microwave for 1 hour, filtered, and the filter residue was mixed with 500 mL×2 mixture of water, ethanol and 1,2-propanediol under the same conditions. The extraction was repeated 2 times under low pressure, the extracts were combined for 3 times, concentrated by distillation under reduced pressure until viscous, and the natural tobacco smoke free radical scavenger III was obtained.

Abstract
The invention discloses a method for preparing a natural tobacco smoke free-radical scavenger and application. The method for preparing the natural tobacco smoke free-radical scavenger is characterized in that the natural tobacco smoke free-radical scavenger uses sesame leaves as raw materials and is obtained by performing solvent extraction and concentrating an extractive. The natural tobacco smoke free-radical scavenger is added into tobacco leaves or a filter tip. When a cigarette is burned, radical in tobacco smoke can be removed, health hazard in smoking is relieved, and simultaneously the method has the effects of softening smoke, removing miscellaneous gas, reducing irritation and improving smoking taste. The method is outstandingly characterized in that a new purpose is opened for the sesame leaves, dried sesame leaves are prepared, and liquid wastes of the dried sesame leaves are utilized to prepare the natural tobacco smoke free-radical scavenger with low cost, and the sesame leaves subjected to extraction can still serve as a dried vegetable to eat after dried.
Description
technical field [0001] The invention relates to the field of tobacco additives, in particular to a preparation method and application of a natural tobacco smoke free radical scavenger. Background technique [0002] Cigarette smoke contains thousands of compounds, free radicals are one of them, and most of these free radicals are harmful to the human body. The free radicals in cigarette smoke can be divided into two categories, one is the free radicals that can be intercepted by the Cambridge filter and exist in the tar, called particle phase free radicals, such as quinone / semiquinone free radicals, polycyclic aromatic hydrocarbon free radicals Radicals, graphitic carbon and phosphorus radicals have larger molecular weights and slightly higher stability. The other type is free radicals that cannot be intercepted by the Cambridge filter, called gas phase free radicals, such as alkane free radicals, alkoxyl free radicals, oxygen free radicals, etc., which are small in weight a...
