Embodiment Construction

[0017] See the examples below.

[0018] (1) Preparation of bamboo leaf extract

[0019] Prepared by solvent-resin method. Long bamboo leaves were collected from Baoshan area in Yunnan. Process: Longzhu Bamboo Leaf Powder→Me 2 CO degreasing, ethanol extraction → ethanol extract → recovery of EtOH, dissolve in water → pretreated D-101 type macroporous adsorption resin → water eluted free sugar and other non-saponins polar components, EtOH elution → EtOH eluate → Activated carbon decolorization, filtration → filtrate → drying → obtain the extract. The molecular structure of the main components of the extract is as follows (where R1, R2, and R3 are about 20 different types of flavonoid molecules):

[0020]

[0021] (2) Add the obtained extract to the cut tobacco of cigarette

[0022] The extract is added to the shredded tobacco during the rolling process of tobacco production. The bamboo leaf extract added to the cut tobacco accounts for 0.04% of the weight of the cut tobacco. The s...

Abstract

This invention relates to the application of crude plant extract in tobacco manufacture, using extract of bamboo leaf as free radical scavenger in tobacco smoking. The added material could be extract in mixed state of multi-component, and could also be one kind of separated extract or mixture of more than one kind. The tobacco could be cigarette, and could also be cigar or cut tobacco for tobacco pipe. If cigarette, the extract of bamboo leaf could be added into the cut tobacco or the filter tip. If the extract is added into the cut tobacco of cigarette, the process could be accomplished during cut tobacco throwing. The extract added into the cut tobacco takes a share of 0.02 to 0.06 percent in the weight of the cut tobacco. The invention has developed a new health care purpose for bamboo leaf, and opened up a new application domain. As free radical scavenger, the extract of bamboo leaf has obvious effect, and has good application prospects in developing safety tobacco of low toxicity and low free radical.

Description

Technical field [0001] The application of natural extracts from plants of the invention in tobacco product manufacturing. Background technique [0002] People smoke the smoke produced by the combustion of tobacco products, but there are free radicals of cytotoxic molecules in the smoke. These cytotoxic molecules induce cancer in smokers, especially lung cancer. The development and production of safe tobacco products with low free radicals is an important research and development direction of the tobacco industry in recent years. [0003] The main active ingredients of bamboo leaf extract are: flavonoids and their glycosides, active polysaccharides, special amino acids and their peptides, manganese, zinc, selenium and other trace elements, as well as aromatic components based on aldehydes and alcohols Wait. [0004] Bamboo leaves have a long history of use in our country and are a traditional heat-clearing and detoxifying medicine. Its medicinal effects are recorded in ancient boo...
