Embodiment 1

[0080] Example 1 The preparation of the total extract of Frangipani frangipani

[0081] Such as Figure 6 Shown is the flowchart of Embodiment 1 of the present invention. Take 500g of dried frangipani medicinal material and crush it to 50 mesh, add 3500g of acetone solution with a volume percentage of 70%, soak at room temperature for 24 hours, and filter to obtain a filtrate. The filter residue was extracted twice under the same conditions to obtain the second filtrate and the third filtrate respectively. All the above-mentioned filtrates were combined and concentrated in a rotary evaporator at 50°C until there was no alcohol smell to obtain the total frangipani extract.

Embodiment 2

[0082] Example 2 The preparation of frangipani total extract

[0083] Take 500g of the dried frangipani herb and crush it to 50 mesh, add 4000g of ethanol solution with a volume percentage of 75%, heat and reflux for extraction for 2 hours, and filter to obtain a filtrate. The filter residue was extracted twice under the same conditions to obtain the second filtrate and the third filtrate respectively. All the above-mentioned filtrates were combined and concentrated in a rotary evaporator at 50°C until there was no alcohol smell to obtain the total frangipani extract.

Embodiment 3

[0084] Example 3 Preparation of Frangipani Total Extract

[0085] Take 500g of dried frangipani herb and grind it to 50 mesh, add 5000g of ethanol solution with a volume percentage of 75%, extract it with ultrasonic wave at 40KHz ultrasonic frequency for 2h, and filter to obtain a filtrate. The filter residue was extracted twice under the same conditions to obtain the second filtrate and the third filtrate respectively. All the above-mentioned filtrates were combined and concentrated in a rotary evaporator at 50°C until there was no alcohol smell to obtain the total frangipani extract.

Abstract

The invention provides a method for extracting (R)-3-carboxyl-alpha-hydroxyphenyl propionic acid from frangipane. The method comprises the following steps: extracting the frangipane through extracting solution, and then filtering frangipane, so as to obtain filtrate; performing concentration treatment on solvent till no alcohol taste exists, so as to obtain frangipane total extract; performing column chromatography isolation and elution on the frangipane total extract, so as to obtain crude products; performing recrystallization on the crude products at the room temperature, so as to obtain (R)-3-carboxyl-alpha-hydroxyphenyl propionic acid. The invention further provides application of the (R)-3-carboxyl-alpha-hydroxyphenyl propionic acid extracted through the method as a tobacco irritation reducing agent, and a cigarette. According to the method, the (R)-3-carboxyl-alpha-hydroxyphenyl propionic acid, with the purity being greater than 98 percent, is extracted for the first time. The compound can be partly transferred to smoke to be combined with free nicotine, or the combination of the compound and the free nicotine is transferred to the smoke, so that the nicotine content of the smoke is reduced, and the irritation of the smoke is reduced.

Description

technical field [0001] The invention belongs to the technical field of cigarette additives, and in particular relates to a method for extracting (R)-3-carboxy-α-hydroxyphenylpropionic acid from frangipani, an application and a cigarette. Background technique [0002] When the cigarette is lit, when the temperature rises to 300°C, the volatile components in the shredded tobacco begin to volatilize and form smoke. Cigarette smoke consists of two parts: gaseous phase and particulate phase. Gas-phase substances account for about 92% of the total flue gas, and particulate-phase substances account for about 8% of the total flue gas. The particulate matter in smoke is mainly water, nicotine and tar. As the main component of smoke, nicotine produces a needle-pricking sensation in the throat and mouth during smoking, which is the source of the irritation felt when smoking. Properly modulating the tobacco leaves, using some flavoring and adding technologies to reduce or remove the ...
