The invention provides a green tea extract as well as a preparation method and application of the green tea extract. The green tea extract is prepared by combining ultrasonic extraction with an elution separation method by adopting macroporous resin. The preparation method comprises the following steps of preparing green tea leaves, carrying out ultrasonic extraction, elution separation by adopting macroporous resin, concentrating and obtaining the extract. After the green tea extract is added into tobacco shreds of cigarettes, the aroma quality of the cigarettes is promoted, the aroma of the cigarettes is pure, mild and fine, and the smoothness of smoke and the aftertaste are obviously improved. Compared with the traditional extracting method, green tea is extracted ultrasonically by using a mixed solvent, so that the use amount of alcohol is greatly reduced, the heating time is reduced, and the extraction rate is obviously improved; by combining with the elution separation by adopting macroporous resin, the content of components in the extract, which have negative influences on smoke of cigarettes, is reduced and the quality and purity of the active ingredients are improved. The preparation method has the advantages that the equipment is easy to operate, no pollution is caused, an improved extraction method with good effect is provided for preparing the green tea extract, and particularly can be favorably applied to tobacco production industry.

The invention relates to a method for preparing extract of yunnan black tea and application thereof. The extract is prepared and obtained by extraction with ultrasonic extraction method and the combination of silica gel chromatographic separation method; the extraction processes comprise fetching of yunnan black tea, ultrasonic extraction, silica gel chromatographic separation, concentration, andobtaining of extract in sequence. When the extract of yunnan black tea is added to the tobacco of cigarettes, the invention can cause the fragrance of cigarettes to be permeable and abundant, the smell of cigarettes to be refined and fine, and the rest smell to be significantly improved in the aspect of comfort. Compared with the traditional extraction method, by using the yunnan black tea which is extracted by the ultrasonic wave of mixed solvent, the dosage ethanol is greatly reduced, the extracting and heating time is shortened, and the extraction efficiency is improved; by combining the silica gel chromatographic separation, the quality and purity of active ingredient is improved. The method relates to uncomplicated equipment, is easy for operation, has no pollution, and provides an improved extraction method which has good effect for the preparation of the extract of yunnan black tea.

The invention provides sheets capable of reducing tar content of cigarettes and a manufacture technology thereof. The sheets comprise the following materials by weight percent: 60-80% of common sheet material, 20-40% of Chinese herbal medicine powder. The sheets has the characteristics of high smoking quality, fresh and sweet mouth feel, delicate smoke, small irritation and little impurity smoke; and after the sheets are added into tobaccos, and the tar content of the cigarettes can be greatly reduced.

The invention relates to a rose flower additive for tobacco and the preparation method and applications thereof. The rose flower additive essentially consists of the rose flowers. The preparation method includes the steps that the rose flowers are extracted by heating and refluxing petroleum ether or ethanol solution or by soaking at ambient temperature; the extracted fluid is filtered and then decompressed and condensed into rose flower soaking cream which is mixed with honey in certain proportion to obtain the rose flower additive for tobacco. The rose flower additive is dissolved in the solution of ethanol and propanediol with certain concentration to form saturated solution, which is then evenly sprayed on cut tobacco, tobacco stems or tobacco sheets which are then prepared into cigarette. The dosage of the rose flower additive accounts for 0.01 to 5percent of the weight of the cut tobacco, the tobacco stems or the tobacco sheets. The rose flower additive is characterized by the harmony of the rose flower fragrance and the tobacco fragrance and can soften the cigarette smoke and reduce the irritation of the cigarette fragrance to the respiratory system and the harm of smoking.
