94 results about "Arecoline" patented technology

Arecoline (/əˈrɛkəliːn/) is a nicotinic acid-based alkaloid found in the areca nut, the fruit of the areca palm (Areca catechu). It is an odourless oily liquid. It can bring a sense of euphoria and relaxation.

Preparation method of standard substance for detecting arecoline in cosmetic

The invention relates to a preparation method of a standard substance for detecting arecoline in a cosmetic. The preparation method is characterized in that a propylene glycol solution of the arecoline is mixed with cosmetic cream to form the standard substance for detecting the arecoline in the cosmetic. The formula of the cosmetic cream comprises a phase A, a phase B, a phase C and a phase D in percentage by weight, namely the phase A comprises 3 to 5 percent of stearate, 2 to 4 percent of alcohol and 10 to 14 percent of #26 white oil; the phase B comprises 38 to 42 percent of propylene glycol, 0.1 to 0.3 percent of carbomer and 36 to 42 percent of deionized water; the phase C comprises 0.1 to 0.3 percent of triethanolamine, and the phase D comprises 1.25 to 1.30 percent of phenoxyethanol and ethylhexylglycerin; and the concentration of the arecoline in the standard substance is 50 mug / g. The preparation method has the advantages that the arecoline is mixed with the cosmetic cream to form the standard substance for detecting the arecoline in the cosmetic; the standard substance is the same as that in a cosmetic sample containing the arecoline in actual use, so that detection on the arecoline in the cosmetic can accord with an application state; and the detection is relatively accurate.

Production method of tobacco areca nuts

The invention discloses a production method of tobacco areca nuts. The method mainly comprises the following steps of selecting fresh areca nuts, washing the selected fresh areca nuts, buffing the washed fresh areca nuts, soaking the buffed fresh areca nuts in calcium hydroxide, cooking the soaked areca nuts, smoking the cooked areca nuts, performing microwave puffing, performing fermentation, performing braising to generate fragrance, performing cutting to obtain slices and removing cores, performing packaging, performing microwave sterilization and the like. Through the adoption of the production method of tobacco areca nuts disclosed by the invention, the content of arecoline and the content of arecaidine in the tobacco areca nuts can be significantly reduced, so that the increased risk that eaters suffer from oral cancer can be reduced, and the tobacco areca nuts are safe to eat; and besides, the prepared tobacco areca nuts are high in puffing efficiency, fluffy, obvious in texture layering, soft in mouth feel, good in flexibility, good in mouth feel and stable in properties. The tobacco areca nuts not only reserve traditional characteristics of being fragrant, sweet and strong, but also have the characteristics of being delicately fragrant in fruity taste, fragrant rather than greasy, unique in mouth feel and flavor.

Capillary electrophoresis electrochemiluminescence detection method for arecoline in traditional Chinese medicine betelnut extract

The invention provides a capillary electrophoresis electrochemiluminescence detection method for arecoline in a traditional Chinese medicine betelnut extract. The method applies capillary electrophoresis ruthenium pyridine electrochemiluminescence analysis technology to the detection of arecoline in the traditional Chinese medicine betelnut extract for the first time, and has the advantages that the operation is simple, the sensitivity is high, the detection limit of arecoline is 5*10<-9> mol / L, the separation function is strong, the pollution is avoided, and the field amplified injection is realized and the separation selectivity of arecoline and coexisting media in the betelnut extract is improved by using ionic liquid BMImBF4 in a buffer. Electrochemiluminescence reagent ruthenium pyridine is reversible in reaction and high in photon yield, thus the reagent consumption is greatly reduced and the detection cost is lowered. The analysis method is green, environmentally friendly and low in sample consumption. The analysis can be finished by adopting a capillary electrophoresis electrochemiluminescence comprehensive analyzer and chemical reagents which are common in laboratory and requiring nonoliter-scale injection volume.

Electronic cigarette tar with betel nut efficacy and preparation method thereof

The invention is applicable to the technical field of electronic cigarettes, and provides an electronic cigarette tar with betel nut efficacy and a preparation method thereof, wherein the electronic cigarette tar comprises the following components by weight: 40 to 60 parts of glycerin, 10 to 25 parts of flavors and fragrances, 25 to 40 parts of propylene glycol, and 0.5 to 2 parts of arecoline. According to the embodiment of the invention, the flavors and fragrances, the propylene glycol, the glycerin and the arecoline are mixed, all the components can be well dissolved, uniform and stable dueto good solubility of the propylene glycol to the flavors and fragrances, and after the components are atomized, steam is sucked by a human body, so that the feeling of redness, heartbeat acceleration and the like caused by eating betel nuts is obvious. By replacing chewed betel nuts with the tobacco tar, harm to the oral cavity of the human body when people chew the betel nuts is reduced, and thus the risk that people suffer from periodontitis, oral cancer and other diseases due to long-term excessive chewing of the betel nuts is reduced; and moreover, a real betel nut feeling can be experienced in the electronic cigarette tar, and the electronic cigarette tar is popular with electronic cigarette users and betel nut enthusiasts.
