Chrysanthemum flower oil can effectively decrease uric acid levels in rats, by reducing production in the liver and enhancing excretion from the kidney.
In this study, the researchers developed a hyperuricemia model by feeding rats a specific chrysanthemum flower oil enriched diet. Hyperuricemia is a condition of elevated uric acid levels which the team sought to decrease. Chrysanthemum flower oil was chosen due to its polyphenol content, substances known to have positive health benefits. By administering this oil orally to rats on this diet, they were able to monitor its impact on the rats' serum uric acid levels.
The results showed that the chrysanthemum oil had a significant impact on controlling and reducing uric acid levels. This was achieved through two primary mechanisms. Firstly, there was a demonstrated inhibition of xanthine oxidase activities in the liver. This enzyme plays a crucial role in the conversion process that leads to the creation of uric acid. Secondly, the oil increased uric acid levels in the urine, suggesting greater excretion of it. This was further confirmed by the up-regulation of uric acid transporter genes in the rats' kidneys, which enhances the excretion process.
