Among them, there are many studies on the hypoglycemic effect of mogroside, and the results show that kaempferin has a better hypoglycemic effect on alloxan-induced rats; mogroside IIIE can activate adenosine monophosphate activated protein kinase (adenosine monophosphate activated protein kinase). , AMPK) signaling pathway inhibits gestational diabetes; another study showed that mogroside can reduce blood sugar by inhibiting the conversion of glucose in food; Yu Wanqin et al found that mogroside extract can activate Keleh-like epichlorohydrin-related protein 1 - Nuclear factor E2-related factor 2/antioxidant response element pathway alleviates oxidative stress damage in gestational diabetic rats, thereby exerting a protective effect on pancreatic tissue. In vitro studies have shown that mogroside can improve the glycolipid toxicity of islet β cells and inhibit cell apoptosis. At the same time, Luo Han Guo also has the function of regulating fat and reducing weight: studies have shown that Luo Han Guo can reduce serum total cholesterol, triacylglycerol and low-density lipoprotein levels in model rats, and increase high-density lipoprotein levels. Song Xiaowan intervened obese mice with mogroside for 18 weeks, and found that mogroside could inhibit obesity, improve systemic glucose tolerance and insulin sensitivity, increase thermogenic gene expression, induce browning of white adipose tissue, and reduce adipose tissue inflammation. Liu et al. found that the hypoglycemic and lipid-regulating effects of mogroside may be related to attenuating insulin resistance and activating liver 5′ protein kinase signaling. In addition, studies have shown that mogrotol can inhibit fatty acid synthesis by activating the expression of cholesterol regulatory element binding protein and fatty acid synthase, which are related factors of AMPK signaling pathway in liver cancer HepG2 cells.

4. Amddiffyn yr Afu
Modern pharmacological studies have shown that mogroside has a certain hepatoprotective effect, among which there are many studies on anti-hepatic fibrosis. Studies have shown that the mechanism of mogroside’s anti-hepatic fibrosis may be to inhibit the activation of hepatic stellate cells and apoptosis of hepatic cells by inhibiting the expression of transforming growth factor-β1 and type I collagen protein and mRNA, inhibit collagen production, and promote extracellular matrix degradation. In addition, studies by Xiao Gang and others have shown that mogroside has a protective effect on the acute liver injury caused by CCl4 in mice, and has a preventive effect on the chronic liver injury caused by CCl4 in rats. Luo Han Guo water extract can also significantly improve the intestinal flora of mice with non-alcoholic steatohepatitis.

5. Effaith Gwrthocsidiol
Modern pharmacological studies have shown that both mogroside and mogroside polysaccharides have antioxidant effects, and there are more studies on mogroside. Qi Xiangyang et al found that mogroside can effectively scavenge free radicals, and has a protective effect on liver tissue peroxidative damage induced by Fe2+ and H2O2. Zhao Yan et al. found that the water extract of Luo Han Guo and mogroside could significantly increase the activity of glutathione peroxidase and superoxide dismutase in high-fat model mice, and reduce the level of malondialdehyde. Xia Xing et al found that mogroside at 0.1-10 μg/mL can alleviate the decrease in the viability of PC12 nerve cells caused by oxidative stress and enhance the antioxidant capacity of PC12 nerve cells. Li Shan et al found that Luo Han Guo polysaccharide P-1 and polysaccharide P-2 have good scavenging effects on various free radicals, and their scavenging ability increases with the increase of polysaccharide concentration, among which polysaccharide P-1 has the strongest antioxidant activity. in polysaccharide P-2. In addition, the study found that Luo Han Guo extract can reduce the expression of cytochrome C oxidase 7A2 protein in rat testis tissue.

6. Anti-tumor Effect
Modern pharmacological studies have shown that Mogrosanol has anti-tumor effects. Mogrosanol can induce apoptosis and cycle arrest by regulating the expression of p21 and B lymphoma-2 genes, thereby promoting the apoptosis of lung cancer A549 cells. Mogrosanol can also significantly inhibit the proliferation of prostate cancer DU145 cells, liver cancer HepG2 cells, lung cancer A549 cells, and nasopharyngeal carcinoma CNE1 and CNE2 cells, among which the inhibitory effect on CNE1 cell proliferation is the most significant, and it is dose-related, probably by promoting Caspase-3, Bax protein and other pro-apoptotic genes and inhibit the expression of anti-apoptotic genes such as lymphoma/leukemia-2 and Survivin B to induce tumor cell apoptosis.

7. Antibacterial and Anti-inflammatory Effects
Modern pharmacological studies have shown that Luo Han Guo has an inhibitory effect on a variety of fungi, and also has a certain anti-inflammatory effect. The invasion of Gram-negative bacteria to the body will lead to the synthesis of inducible nitric oxide synthase and cyclooxygenase 2 induced by lipoproteins on the cell wall. Mogroside can inhibit the dislocation of nuclear factor κB caused by exogenous lipopolysaccharide by preventing the activation of mitogen-activated protein kinase signal transduction pathway, thereby reducing lipoprotein-induced inducible nitric oxide synthase and cyclooxygenase 2 protein levels. Wang Haiyang et al. extracted and isolated three compounds, hexadecanoic acid, cyclo-(leucine-isoleucine) and sitosterol-3-O-glucose, from Luo Han Guo, and the research showed that all three compounds are harmful to the large intestine. Bacterial biofilms are inhibited. In addition, Luo Han Guo also has a certain inhibitory effect on Escherichia coli, Staphylococcus aureus, Bacillus subtilis, Rhizopus and Aspergillus. Li et al. found that mogroside V plays an anti-inflammatory effect by blocking the activation, production and expression of nuclear factor κB, human CCAAT enhancer-binding protein δ, reactive oxygen species, and activator protein-1/heme oxygenase 1. Another study showed that mogroside IIE could improve pancreatitis in cell models and mice by down-regulating the interleukin-9 receptor pathway.
