Problems solved by technology
However, all of the above methods require centrifugation to separate the aqueous solution from the organic solvent. On the one hand, the application of large-volume aqueous solution samples is limited, and on the other hand, the enrichment factor is small.
In addition, the use of dispersant will also reduce the extraction efficiency

The invention provides a method for analyzing water-soluble essential oil components in sweet-scented osmanthus by ultrasonic in-situ generation of carbon dioxide gas bubbling-assisted dispersion liquid-liquid microextraction technology combined with gas chromatography / mass spectrometry. The combination of demulsification and dispersion liquid-liquid microextraction technology overcomes the problem of using centrifugation for demulsification in the traditional dispersion liquid-liquid microextraction method, and has the characteristics of high enrichment multiple and short time consumption. The present invention uses ultrasonic bubbling to assist demulsification technology, so that the emulsion quickly becomes clear without additional centrifugal equipment, the equipment required by the invention is simple, the operation is easy and the operation time is short, and it can be applied to the pretreatment operation of samples of different volumes. The application of the invention can be combined with reality, which is A new method that can quickly and efficiently extract water-soluble essential oil components in osmanthus fragrans, and provides a new means for extracting water-soluble essential oil components of other plants.
Description
[0001] (1) Technical field [0002] The invention relates to a method for analyzing water-soluble essential oil components in osmanthus fragrans, in particular to a method for analyzing water-soluble essential oil components (aromatic water) in osmanthus fragrans by ultrasonic in-situ generation of carbon dioxide gas bubbling-assisted dispersion liquid-liquid microextraction technology combined with gas chromatography / mass spectrometry and immersion of volatile components in water) method. [0003] (2) Background technology [0004] Osmanthus fragrans, a plant belonging to the genus Oleaceae Oleaceae, is widely distributed in China, Japan, Southeast Asia and some European countries. Osmanthus fragrans has a cultivation history of 2,500 years in my country and is one of the ten traditional famous flowers in my country. Osmanthus fragrans was known as the tree of immortals as early as the Eastern Han Dynasty because of its special fragrance. "Wu Gang Cutting Osmanthus" is a well...
