Abstract

The invention relates to a new application of oleic acid and glycerol 1-monooleate in the preparation of a kit for evaluating the intestinal lipid accumulation in a tested organism and its intervention effect, and a detection method of the oleic acid and the glycerol 1-monooleate. A reagent and the method are used to detect the content of the oleic acid and the glycerol 1-monooleate in the intestinal tissues of the tested organism. The invention further provides the method for detecting the content of the oleic acid and the glycerol 1-monooleate in the intestinal tissues of the tested organismthrough gas chromatography-mass spectrometry. The content can be used for evaluating the intestinal lipid accumulation and its intervention effect. The kit and the detection method have the characteristics of simplicity in operation, good reliability, fastness, high sensitivity, high specificity, and easiness in promotion.

Description

technical field [0001] The invention relates to the new application of oleic acid and 1-monoolein in the preparation of reagents or kits and detection methods for evaluating intestinal lipid accumulation and its intervention effect, and belongs to the fields of analytical chemistry, biochemistry and medicinal chemistry. [0002] technical background [0003] With the development of the economy and the change of lifestyle, the prevalence of risk factors for cardiovascular disease in my country is becoming more and more obvious, leading to a continuous increase in the morbidity and mortality of cardiovascular disease. At present, cardiovascular disease accounts for more than 40% of residents' death from diseases, and is the first cause of death among residents. It has become a major public health problem, and its prevention and treatment is urgent. Cardiovascular disease is closely related to lifestyle, especially diet, smoking, exercise and psychological stress. According to ...
