Abstract

The invention discloses a method for measuring organic acid in hawthorn tincture used in cigarettes, which is characterized by comprising the steps of: adopting methanol, water, glacial acetic acid and triethylamine as a quaternary mobile phase, isocratic-eluting, and detecting by adopting a high-performance liquid chromatography-diode array detection method. In the method for detecting the content of oleanolic acid and ursolic acid in hawthorn tincture, when the sample is pretreated, a hawthorn tincture sample only needs to be diluted with the methanol, and then filtered with a 0.45-Mum filter membrane for liquid chromatographic separation and analysis without interference of other impurities; in addition, the method has the advantages of being simple, convenient and fast, having wide linear range, good separation effect and accurate and reliable data, and the like.

Description

technical field [0001] The invention relates to the technical field of chemical analysis and detection, in particular to a method for determining organic acids in hawthorn tincture for tobacco. Background technique [0002] Hawthorn tincture is obtained by extracting mature hawthorn fruit with ethanol, heating and continuous circulation reflux extraction, and recovering the solvent. It has a unique aroma and is rich in a variety of active ingredients that are beneficial to the human body. Therefore, it is widely used as a fragrance raw material. Applied to cigarette flavoring. However, due to the large differences in the extraction processes of various production enterprises, the quality of the hawthorn tincture obtained is uneven. Therefore, for cigarette industry enterprises, it is necessary to select appropriate chemical composition indicators of hawthorn tincture to control its quality. At present, the index components for the content determination of hawthorn tincture...
