Problems solved by technology

[0006] At present, the addition and application of Chinese herbal medicines and their extracts in the industry are still mainly based on the functional application of single Chinese medicines, and the application of compound prescriptions still uses relatively simple function superposition, which is still comparable to the syndrome differentiation and treatment, diagnostics and prescriptions of Chinese medicine. However, it cannot be regarded as a scientific application under the guidance of the motherland's medicine.

[0028] Cytotoxicity Evaluation of Natural Plant Tobacco Harm Reduction Additives Added to Tobacco Smoke

[0029] 1 Purpose of the test

[0030] To evaluate the cytotoxicity of cigarettes with different treatments.

[0031] 2 test items

[0032] There are 7 kinds of cigarettes, labeled as control cigarettes and experimental cigarettes (natural tobacco with harm-reducing additives, the addition ratios are 0.02%, 0.05%, 0.1%, 0.2%, 0.5%, and 1%).

[0033] 3 test plan

[0034] 3.1 Preparation of Tobacco Condensate (CSC)

[0035] Collect cigarette smoke according to standard smoking conditions (GB / T16450-1996, standard conditions defined by smoking machines for routine analysis), prepare smoke condensate (CSC), and prepare a solution of 1 cigarette / ml with cell culture medium, - Store at 80°C for later use. When experimenting, dilute to the experimental design concentration.

[0036] 3.2 Cell culture

[0037] Beas-2B cells were cultured in serum-free LHC-8 medium at 37°C, 5%...

Embodiment 1

[0047] Take Epimedium, Eclipta, sweet almond, motherwort, dandelion and Huajuhong respectively, grind them and mix them uniformly according to the ratio of 0.5:0.5:0.2:0.3:0.3:1, add 8 times the amount of pure water, soak for 2 hours, 75 Heat reflux at ℃ for 1 hour, extract 3 times in total, combine the extracts from the 3 times, concentrate at 80 ℃ and pressure 0.02Mpa to a fluid extract with a density of 1.12. Add 2 times the volume of ethanol, let it stand for 24 hours, filter the precipitate, concentrate to a density of 1.12 liquid extract under the conditions of 80°C and a pressure of 0.02Mpa, and filter to obtain the harm-reducing additive for tobacco. Take 10g of the additive, dissolve it in 20kg of distilled water, spray it on 500kg of shredded tobacco, and roll it into cigarettes.

Embodiment 2

[0049] Take Epimedium, Eclipta, Sweet Almond, Motherwort, Dandelion, and Juhong respectively, grind them and mix them evenly at a ratio of 1:0.8:0.5:0.5:0.5:1, add 6 times the amount of pure water, soak for 6 hours, and 70 ℃ heat reflux extraction for 1.5h, a total of 3 extractions, combined 3 extracts, 75 ℃, concentrated under the conditions of pressure 0.06Mpa to a density of 1.11 liquid extract. Add 2 times the volume of ethanol, let it stand for 36 hours, filter the precipitate, concentrate at 75°C and a pressure of 0.06Mpa to a liquid extract with a density of 1.11, and filter to obtain the harm-reducing additive for tobacco. Take 50g of the additive, dissolve it in 20kg of distilled water, spray it on 500kg of shredded tobacco, and roll it into cigarettes.

Abstract

The invention discloses a harm reducing additive for cigarettes as well as a preparation method and an application of the harm reducing additive. The additive comprises natural plant extract compositions or compound natural plant extracts, wherein the natural plants comprise herba epimedii, eclipta, sweet almond, leonurus, dandelion and pummelo peel. The additive is prepared according to the following methods that the herba epimedii, the eclipta, the sweet almond, the leonurus, dandelion and the pummelo peel are respectively extracted by solvents and refined, and are then prepared into the harm reducing additive for cigarettes according to a proportion being (1-8):(0.8-6):(0.5-4):(0.3-4):(0.3-5):1; or the herba epimedii, the eclipta, the sweet almond, the leonurus, the dandelion and the pummelo peel are mixed according to a proportion being (0.5-8):(0.5-6):(0.2-4):(0.3-4):(0.3-5):1, then, solvents are used for extraction and refining, and the harm reducing additive for cigarettes is prepared. The additive is added into cut tobacco, shredded stem and thin slices of cigarette, and the addition proportion is 0.002 to 1 weight percent. Compared with the prior art, the harm reducing additive for cigarettes has the advantage that through being proved by smoke gas pharmacology and toxicology study, a clear biological harm reducing effect can be realized after the harm reducing additive is added to the cigarettes.

Description

technical field [0001] The invention relates to the fields of tobacco additives and their preparation and application, in particular to a cigarette additive containing a combination of natural plant extracts or compound natural plant extracts, which has moisturizing and flavor-enhancing effects, and its preparation and application. Background technique [0002] Since the early 1950s, when the Royal Society of Medicine first reported the official report on the health hazards of smoking, smoking and health issues have always been highly valued by governments, the tobacco industry and the medical profession. In the face of calls for tobacco control worldwide, smoking and health have naturally become the focus of attention of the whole society. Therefore, cigarette harm reduction has become the overall direction and research focus of the development of tobacco technology in the country and even the world. The production of "low-harm, high-aroma" cigarettes is not only an industr...
