Problems solved by technology

According to this step, it takes about 4-6 hours to process a sample, which is time-consuming and labor-intensive, and wastes a lot of organic solvents, which is not good for human health and damages the environment.
Moreover, the traditional sample derivatization method has a low recovery rate of only about 83.6%, and the derivatization reagents also need to be used and prepared immediately, which brings inconvenience to the operation.

Abstract

This invention discloses a test method for the effective components in fat oil, which applies the HPLC method to reduce the derivation operation steps of a sample and save time and reagents, not necessary to apply the step of extraction and applies suitable chromatograph conditions to separate the target components from impurities completely.

Description

technical field [0001] The invention relates to a method for determining effective components in fatty oils. Background technique [0002] Fur seals are deep-sea mammals that live in cold waters below the Arctic Circle at -50°C. They feed on rare cod, have a thick layer of fat under their skin, and are rich in omega-3 polyene fatty acids. The seal fat oil extracted from the seal fat of the pollution-free sea area in northern Canada contains three important omega-3 polyene fatty acids-EPA (Eicosapentaenoic Acid, Eicosapentaenoic Acid), DPA (Docosapentaenoic Acid, twenty Two carbon pentaenoic acid) and DHA (Docosahexaenoic Acid, docosahexaenoic acid), and the total content is more than 20%. After years of research in the medical field, it has been confirmed that these three fatty acids have a variety of unique biological activities on the human body: EPA can improve blood circulation, soften blood vessels, adjust blood lipids, lower blood pressure and blood sugar, and anti-in...
