In the present study, supplement of natural sweetener from Siraitia grosvenorii(SG)(or Momordica grosvenorii) fruit, compared with the artificial sweetener aspartame(ASM), was evaluated for anti-obesity effects on mice fed with high fat diet(HFD). We found that, in contrary to ASM, SG extracts prevented body weight gain, the insulin resistance and fat mass accumulation in HFD mice. SG extracts treatment inhibited the infiltration of inflammatory macrophages and lowered the levels of the fat inflammatory cytokines(leptin, macrophage chemoattractant protein 1(MCP-1) and tumor necrosis factor-α(TNF-α)) in adipose tissues. In addition, SG extracts supplement counteracted the remodeling of gut microbiota resulted from HFD. However, ASM supplement aggravated the HFD-induced obese performances, fat inflammation and dysregulation of gut microbiota. Taken together, our results indicate that supplement of SG extracts may represent a promising alternation of artificial sweeteners in preventing metabolic diseases.展开更多

The results showed that female triploid and male diploid individuals of S. grosvenorli had abundant genetic background, with great genetic similarity cecfficients and close genetic distance. Overall, the genetic background of female triploid and male diploid individuals of S. grosvenorii exhibited relatively low complexity. Therefore, it is necessary to take corresponding measures for germplasm innovation to enrich the genetic background of seedless parents of S. grosvenorii.展开更多
