Synergistic Effects of Chlorogenic Acid and Ganoderma Lucidum Polysaccharide on Hepatic Fat Accumulation

Abstract

This study aimed to investigate the impact of different doses of chlorogenic acid and Ganoderma lucidum polysaccharide on lipid accumulation using an obese rat model. We utilized blood glucose assays, oil red O staining, and triglyceride content analysis to examine the effects of chlorogenic acid combined with G. lucidum polysaccharide on fat metabolism in rats. We found substantial potential in using chlorogenic acid combined with G. lucidum polysaccharide for weight control and metabolic regulation in obese rats. After a long-term dietary intervention, chlorogenic acid and G. lucidum polysaccharide markedly inhibited the expression of proteins related to fatty acid synthesis, including AMP-activated protein kinase, fatty acid synthase, and SREBP-1c, leading to reduced body weight and decreased hepatic fat deposition. Additionally, the combined treatment substantially affected enzymes and proteins involved in glucose metabolism, reducing glycogen synthase expression and indicating a potential mechanism for weight reduction through glycogen synthesis inhibition. Furthermore, elevated glucose kinase levels indicated that chlorogenic acid and G. lucidum polysaccharide may enhance hepatic glycogen degradation, thereby reducing hepatic fat accumulation. These findings reveal that chlorogenic acid combined with G. lucidum polysaccharide has a synergistic impact, providing a theoretical basis for their potential as a combined therapeutic approach for obesity.
