Embodiment Construction

[0016] Below in conjunction with specific embodiment the method of the present invention is described in detail:

[0017] The method for detecting the imperatorin in the tincture of Angelica dahurica, the fragrance raw material for tobacco, of the present invention specifically comprises the following steps:

[0018] High performance liquid chromatography conditions:

[0019] Chromatographic column: waters SymmetryC18 column (4.6mm×250mm×5μm)

[0020] Flow rate: 0.8mL / min

[0021] Column temperature: 30°C

[0022] Detection wavelength: 254 nm

[0023] Injection volume: 10μL

[0024] Mobile phase: methanol-water (70:30, v / v)

[0025] Elution method: isocratic elution

[0026] 1) Establishment of standard working curve

[0027] Precisely draw a certain amount of imperatorin storage solution, dilute it with methanol, and make standard samples of different concentrations, carry out according to the above liquid chromatography conditions, take the injection concentration (μg...

Abstract

The invention discloses a method for determining the content of imperatorin in perfume material angelica officinalis tincture for cigarettes, which is characterized by taking the mixed liquor of methanol and water as a mobile phase, and using a high performance liquid chromatography to detect, wherein the detector used by the high performance liquid chromatography is a diode array detector. In the method for detecting the content of imperatorin in perfume material angelica officinalis tincture for cigarettes, methanol and water are simultaneously taken as mobile phases and diluent of a sample, thus the pretreatment of the sample is relatively simple; and the high performance liquid chromatography separates matrix interferential peakbase of a target compound and the sample, thus ensuring more accurate detection result and more reliability.

Description

technical field [0001] The invention belongs to the technical field of chemical analysis and detection, and in particular relates to a method for determining imperatorin in tincture of angelica dahurica, a flavor raw material for tobacco. Background technique [0002] Angelica dahurica is a plant of the umbrella family Angelica dahurica ( Angelica dahurica Benth. Et Hoor. f. ) or the dry root of Hangbaizhi. Warm in nature and pungent in taste, the function is to disperse wind and dehumidify. The chemical components contained in Angelica dahurica are mainly volatile oil. Modern pharmacological experiments have shown that imperatorin contained in Angelica dahurica is one of its important active ingredients. [0003] Angelica dahurica tincture is obtained by extracting Angelica dahurica with ethanol, heating and continuously circulating under reflux, and recovering the solvent. Because the tincture of Angelica dahurica has the typical herb-like aroma of the root of Angelica...
