[Abstract]:In recent years, the development and production of new marine medical foods, such as anti-cancer, anti-cancer, antioxidation and anti-aging, have gradually become a hot spot. The analysis and determination of active components in marine medical foods are mostly high performance liquid chromatography, liquid chromatography mass spectrometry and gas chromatography-mass spectrometry. However, these methods usually require complex preconditioning. The operation process is tedious, time-consuming and pollute the sample. Therefore, this kind of technology can not meet the needs of rapid detection in the process of safety production and supervision of marine medical food. The atmospheric mass spectrometry ion source can be used for rapid analysis and analysis of complex matrix samples without the sample pretreatment. A new type of droplet spray ion source mass spectrometry (DSI-MS) was developed to develop a new type of droplet spray ionization mass spectrometry (DSI-MS). A new type of mass spectrometric droplet spray ion source was developed for rapid detection of active components in marine medical food. A new type of droplet spray mass spectrometry ion source is constructed based on the carrier of the tip of the slide plate, and a new type of droplet spray ion source mass spectrometry is set up to optimize the related parameters to obtain reliable, stable and efficient ionization efficiency. Based on this, the ionization source ionization of droplet spray is further studied. Mechanism. With Meglumine Adenosine Cyclophosphate Injection, Adenosine Disodium Triphosphate Injection, injection of adenosylmethionine butyl two and other medical injections as the research object, the feasibility of rapid analysis and detection of effective components of marine medical food by a new droplet spray ion source mass spectrometry was verified. For the marine medical food with different forms (solid and liquid), a rapid qualitative analysis method for the active components of marine medical food was developed by a new type of droplet spray ion source. The effects of the parameters of taurine on the response of the sulfonic acid signal, such as ionization mode, spray solvent, space position and spray voltage, were investigated, and the solid and liquid were constructed. Based on the DSI-MS method, a rapid qualitative analysis of taurine samples (3 solid samples and 3 liquid samples) from 6 different manufacturers was carried out. The active components of the 6 samples were quickly and accurately detected. Based on the new droplet spray ion source mass spectrometry, a new type of droplet spray ion source - Marine medical food was established A rapid quantitative method for analysis of active components. The effects of ionization mode, space position and spray voltage on the response of adenosine monophosphate signal were investigated with the model of arabinosine monophosphate monophosphate monophosphate from spongy adenosine adenosine as a model. The characteristic fragment ion (m/z) of adenosine monophosphate, such as MS/MS, was used. 211) for the quantitative ion, the linear regression equation y=96.44 x-389.08 is established, the linear correlation coefficient R2 is 0.99, the detection limit is 1.7 ng/mL, and the recovery rate of the standard concentration at 5~50 ng/m L is between 91.7%~111.0%. On this basis, the active components in the long Fu brand, Datong brand and the first strong brand Vidarabine Monophosphate for Injection are quantitatively analyzed. The content of the sex components is 18.06,19.19 and 20.16 ng/mL respectively, and the relative standard deviation (RSD) is 6.6%, 6.6% and 6.9%. respectively. In this paper, a new type of droplet spray ion source mass spectrometry is constructed in this paper, and a new type of droplet spray ion source, marine medicine, is established for the rapid analysis of the active components in marine medical food. The fast qualitative and quantitative analysis method of food active ingredients has been successfully applied to the rapid qualitative and quantitative analysis of the non morphologic marine medical food. The method has the advantages of very strong resistance to matrix interference, short analysis time, no pollution, stability, simple operation and so on. This topic is a fast active ingredient in the current domestic marine medical food. The analysis and testing provide theoretical and practical basis, which will help the safety production and standardized production of marine medical food, promote the establishment of related industry standards, and further promote the development and utilization of marine medical food.
