The invention also discloses a preparation method of the novel moth wash. The preparation method comprises the following steps of S1, raising a temperature of waterto 80 to 90 DEG C, carrying out heat preservation for 12 to 30 minutes, lowering the temperature to normal temperature, then adding sorbitol, glycerol, a sweetener and allantoin, and agitating untilcomplete dissolution, so as to obtain a phase A; S2, mixing the organosilicon quaternary ammonium salt, peppermint oil, anethole oil, menthol and WS-3, and then agitating for 15 to 30 minutes, so as to obtain a phase B; S3, mixing the phase A in the step S1 and the phase B in the step S2, and agitating until transparency, so as to obtain the novel mouth wash. The mouth wash provided by the invention has favorable mouthfeel, has no irritation to a human body while enhancing cleaning and bacteriostatic effects, and further has no toxic and side effects on the human body.

The invention relates to a quality control method for volatile components of Shenbao tablets. The invention discloses a quality control method. The method comprises the step of measuring the contentsof volatile components, namely trans-anethole and ligustilide, in the Shenbao tablet. The method comprises the following steps: (1) testing chromatographic conditions and system applicability; (2) preparation of a reference substance solution: preparing a proper amount of trans-anethole reference substance, and adding an extraction solvent to prepare the reference substance solution; (3) preparation of a test solution: crushing the Shenbao tablets, adding the extraction solvent, carrying out ultrasonic treatment, filtering the liquid, and collecting a subsequent filtrate; and (4) determination: precisely sucking the reference substance solution and the test solution respectively, injecting into a liquid chromatograph, and determining the results. The content determination method established by the invention provides a reliable way for quality control of volatile components in the Shenbao tablets, and can control the product quality more comprehensively.

The present invention relates to a process for preparing arylpropenes, especially 1-methoxy-4-(1-propenyl)benzene (anethole), by means of thermolysis of the corresponding 1,1-diarylpropanes.

The invention discloses an extraction method of linalool. The extraction method comprises the following steps: (1) extracting fennel oil from fruits and leaves of aniseed; (2) rectifying to separate a front cut fraction (30 percent of estragole) generated in the process of preparing anethole from the fennel oil, and obtaining 80 percent of estragole and about 12 percent of terpilenol azeotrope; and (3) placing the azeotrope obtained in the step (2) into a high-performance rectifying tower, intermittently feeding the materials, efficiently rectifying separating, adjusting a reflux ratio and a vacuum degree at three kettle temperature stages of 80 DEG C, 95 DEG C and 110 DEG C, placing the obtained head oil into a high-performance separation tower, controlling the kettle temperature at 50 to 60 DEG C at the low pressure less than or equal to 100Pa, collecting a fraction of 45 to 48 DEG C, adjusting the temperature to 70 to 110 DEG C, collecting the fraction of 65 to 84 DEG C, adjusting the temperature to 110 to 125 DEG C, and collecting tail oil. The front cut fraction generated in the anethole extraction process is used as the raw material, so that the price is low; and the processing is carried out on the basis of the existing equipment, so that the operation is simple, the equipment depreciation is reduced, and the enterprise benefit is increased. No additive is adopted, so that the extraction method of the linalool is natural and environment-friendly.

The present invention provides a flavour composition which is a mixture of flavour materials, characterised in that the flavour composition comprises at least 8% by weight of the total weight of the flavour composition of ingredients selected from the following groups of flavour materials: (a) at least 0.5% by weight of the flavour composition of one or more of the following: a peppermint oil comprising 1-isopropylidene-4-methyl-2-cyclohexanone in an amount from 1% to 4% by weight, 5-methyl-2-(1-methylethyl)-1-cyclohexanone in an amount from 8% to 13% by weight and less than 0.5% by weight of eucalyptol; a spearmint oil comprising less than 70% by weight of carvone and at least 14% by weight of limonene; or mixtures thereof; and (b) at least 0.5% by weight of the flavour composition of two or more of the following: decanol, octanal, allyl hexanoate, anethole, aniseed rectified, basil oil, benzyl butyrate, camomile oil, cinnamic aldehyde, cis-3-hexenyl acetate, citral natural, citronella ceylon, ethyl heptanoate, eugenol, fennel sweet, geranyl acetate, ionone alpha, lime, orange flavour, para cresyl methyl ether, pinene alpha. These materials have been identified as capable of inhibiting the production of odoriferous volatile sulphur compounds by microorganisms present in the oral cavity, and so to possess hitherto unappreciated oral malodour reducing properties.

The invention discloses a trans-anethole oxygenase mutant, and a mutant strain. When the amino acid sequence of the trans-anethole oxygenase mutant is compared with the amino acid sequence of wild-type trans-anethole oxygenase, it is found that the 319th site amino acid proline is replaced by serine, and the amino acid sequence of the trans-anethole oxygenase mutant is represented by SEQ ID NO 1.According to a construction method, error-prone PCR is adopted, random mutation of trans-anethole oxygenase is realized, introduction into E.Coil BL21(DE3) is carried out, and the mutant strain 4C7 isobtained through screening. The conversion rates of the trans-anethole oxygenase mutant on anisaldehyde and veratraldehyde are 2.05 and 2.38 times of those of an original bacterial strain; the trans-anethole oxygenase mutant is more suitable for industrialized production; production cost is reduced; and production efficiency is increased obviously.
