Abstract

The invention discloses a method for extracting Dendranthema indium leaves and application of an extractive thereof in cigarettes, and belongs to the technical field of cigarette flavors. The method for extracting the Dendranthema indium leaves comprises the following steps: (1) crushing the leaves into coarse powder; (2) performing enzymolyisis on the coarse powder of the Dendranthema indium leaves; (3) extracting volatile oil completely from the mixed feed liquid after enzymolyisis to obtain a yellow transparent oily matter, dissolving the oily matter into ethanol to obtain extracting solution A; (4) filtering the remained mixed feed liquid after extraction of the volatile oil, evaporating the filtrate to dryness to obtain dry extract, and drying the filtration residue in an oven at low temperature; and (5) combining the dry extract with the residue, and refluxing and extracting the dry extract and the residue to obtain an extracted perfume material B. The extracting solution A is flavored in a ratio of 0.01-0.08 percent; and the extracted perfume material B is prepared into solution, and is charged in a ratio of 0.05-0.2 percent. The method is simple and easy to implement, and the extracted perfume material has good flavoring and charging effects on the cigarettes.

Description

technical field [0001] The invention belongs to the technical field of flavors for tobacco, and in particular relates to a method for extracting flavors and flavors from discarded Shennong chrysanthemum leaves, and the application of the extract in cigarettes. Background technique [0002] Shennong chrysanthemum leaves are the dry leaves of Dendranthema indicum (L.) Des Monl.vararomaticum, a plant of Compositae. It has the effects of improving eyesight, clearing heat and detoxifying, dispersing wind and lowering blood pressure, and is used as a folk medicine for pungent coolness and heat-clearing medicine. Because of its special rich aroma, folks use its flowers and leaves to dry in the shade as sachets. Shennong fragrant chrysanthemum has been used as a fragrance material in cigarettes, but its leaves are generally discarded. For the development and research of Shennong fragrant chrysanthemum leaves, there is no report. Contents of the invention [0003] Aiming at the ...
