preparation example Construction

[0044] The preparation method of the isobenzofuran compound of the present invention is prepared by taking tobacco as raw material, extracting extract, organic solvent extraction, MCI decolorization, silica gel column chromatography and high performance liquid chromatography separation steps, specifically:

[0045] A. Extraction of extract: crush the tobacco to 20-40 meshes, ultrasonically extract 2-5 times with a solvent 5-10 times the weight of tobacco, 30-60 minutes each time, combine the extracts and filter, and concentrate the filtrate under reduced pressure to the original 1 / 4 of the volume, let it stand, filter out the precipitate, and then concentrate the resulting filtrate under reduced pressure into extract a;

[0046] B. Organic solvent extraction: add water with a weight 1 to 2 times the weight of the extract a to the extract a, then extract 3 to 5 times with an organic solvent equal to the volume of water, combine the organic solvent extraction phases, and then com...

Abstract

The invention relates to an isobenzofuran compound capable of improving the cigarette suction throat comfort and a preparation method and application of the isobenzofuran compound, and belongs to the technical field of phytochemistry. The compound is separated from cigarettes and tobaccos; the compound is named 5-methoxy-2,2-dimethyl-7,9-dihydro-2H-furo[3,4-]chromene, the English name is 5-methoxy-2,2-dimethyl-7,9-dihydro-2H-furo[3,4-]chromene, the molecular formula is C14H16O3 and the structural formula is as shown in a formula (I). According to the preparation method, the compound is prepared through extract extraction, organic solvent extraction, MCI decoloration, silica-gel column chromatography and high-performance liquid chromatography separation on the cigarettes and tobaccos as the raw material. By adding the compound to a cigarette filter, the cigarette suction throat comfort can be improved and the compound has an obvious throat moistening effect.

Description

technical field [0001] The invention belongs to the technical field of phytochemistry, and specifically relates to an isobenzofuran compound extracted from tobacco for the first time, a preparation method and application thereof. The compound has the effect of significantly improving the throat comfort of cigarette smoking, and can be used as a cigarette mouthpiece additive to improve the smoking quality of cigarettes. Background technique [0002] Nicotiana is an annual or limited perennial herbaceous plant belonging to the family Solanaceae. Among them, N.tabacum L. is the most widely cultivated. Its mature leaves are important raw materials for the cigarette industry and a crop with high economic value. In addition to being mainly used for smoking, tobacco has other extensive uses. At the same time, tobacco is the plant with the most complex chemical composition in the world, and its secondary metabolites are very rich. After decades of research, people have identified m...
