•The investigation of the effect of amorfrutin 1 on insulin resistance in C57BL/6 mice induced by a high-fat diet showed that the treatment group with amorfrutins 1 at 100 mg∕kg∕d for 23 days experienced an increase in insulin sensitivity along with a decrease in blood glucose during oral glucose tolerance and intraperitoneal insulin sensitivity tests.
