In this study, the content of water, water extract, total ash, fat, amino acids, proanthocyanidins, flavonoids and trace elements was determined in the formula tea composed of buckwheat, corn whisker and Jerusalem artichoke, and the effect of formula tea extract on glycolipid metabolism of HepG2 cells was evaluated by cck-8 staining absorbance (OD value), oil red O staining, triglyceride (TG) value, glucose content and liver glycogen content by HepG2 cell fat accumulation model. Reveal its effects on blood glucose value, blood lipids and related mechanisms. The nutrient test results show that the medicinal tea product meets the green tea bag tea standard GB/T24690-2018, and is rich in fat, amino acids, proanthocyanidins, flavonoids, total sugars, proteins and trace elements. The results of the glycolipid metabolism cell model showed that there was no significant difference in the survival rate of HepG2 cells after the treatment of this formula tea compared with the control, indicating that there was no obvious killing effect on cells. In addition, the tea soup extract had obvious hypoglycemic and lipid-lowering effects on HepG2 cell models, and could promote the conversion of glucose into hepatic glycogen, but had no significant effect on the content of triglycerides in cells. This formula tea can be used as a daily drink for diabetics, effectively regulating blood sugar and improving their quality of life.
