Embodiment 1

[0117] Embodiment 1. Detection of finished cigarette shredded tobacco

[0118] 1. Preparation of tobacco matrix matching series standard solutions

[0119] 1.1 Preparation of shredded tobacco matrix solution: stripped shredded tobacco of 2 control cigarettes without the characteristic components of Usneaaceae plants, extracted with 20mL internal standard extraction solution, ultrasonicated for 20min, and filtered. Add 10 mL of saturated saline and 0.5 mL of 5% hydrochloric acid to the filtrate, shake for 10 min, centrifuge at 6000 rpm for 10 min to fully separate the two phases, and remove the water phase. After the organic phase was dried over anhydrous sodium sulfate, it was filtered through a PTFE filter membrane (0.45 μm), and the filtrate was continued for use.

[0120] 1.2 Preparation of matrix-matched standard solution: pipette 2.0mL cut tobacco matrix solution into six nitrogen-blown bottles, and purge until the solution is nearly dry under nitrogen protection. Then ...

Embodiment 2

[0142] Example 2. Detection of cigarette mainstream smoke

[0143] 1. Preparation of flue gas matrix matching standard solution

[0144] 1.1 Preparation of smoke matrix solution: According to GB / T 5606.1-2004 national standard and ISO 3308:2012 tobacco industry standard, 20 pure shredded tobacco cigarettes were smoked with a turntable smoking machine, and the total particle phase was collected by the Cambridge filter things. The filter was extracted with 40mL internal standard extraction solution, and ultrasonicated for 15min. Remove the filter, add 10mL saturated saline and 0.5mL 5% hydrochloric acid to the extraction solvent, shake for 10min, centrifuge at 6000rpm for 10min to fully separate the two phases, and remove the water phase. After the organic phase was dried over anhydrous sodium sulfate, it was filtered through a PTFE filter membrane, and the filtrate was continued for use.

Abstract

The invention relates to a method for detecting characteristic component of usneaceae plant in a tobacco sample. The method comprises the following steps: a) extracting the tobacco sample by an internal standard substance-containing extraction solvent to obtain a sample solution; b) using characteristic component of the usneaceae plant, an internal standard substance and the extraction solvent to prepare the standard solution with a series of concentration; c) using a gas chromatography-mass-spectrography method for determining the characteristic component of the usneaceae plant in the standard solution with a series of concentration, drafting a standard work curve; d) using the gas chromatography-mass-spectrography method to determine the content of the characteristic component of the usneaceae plant in the sample solution, employing an internal standard curve method for quantification; and e) calculating the content of the characteristic of the usneaceae plant in the tobacco sample. The method has the advantages of good repeatability and high analysis detection sensitivity.

Description

technical field [0001] The invention belongs to the field of tobacco, and in particular relates to a method for detecting characteristic components of Usneaceae plants in a tobacco sample. Background technique [0002] Usnea plant extract has a unique natural fragrance and rich resinous smell, and the fragrance lasts for a long time. It is an important natural fragrance. Usneaceae plant extracts can enhance the flavor of old cigarettes after being used for flavoring cigarettes, cover up the miscellaneous and earthy smell of tobacco, set off the unique style of cigarettes, give cigarettes a moss-like green fragrance style, and significantly increase the smoke concentration. And it can improve the comfort of the mouth and throat, and also plays a pivotal role in the deployment of tobacco flavors. [0003] Usnea family plant extracts have different processing techniques, and the products exist in the form of extract or absolute oil, which also contains a large amount of impuri...
