ABSTRACT
The type 2 diabetes rat model was induced with high-sugar and high-fat diet combined with low-dose STZ. This study investigated the hypolipidemic mechanism of Coptis chinensis and C. deltoidea. After 30 days of administration, HOMA-IR and the content of TG in serum were detected, and the expressions of SCAP, SREBP-1c were tested by the method of Western blot and Real-time PCR analysis. The test results showed that both components can significantly alleviate insulin resistance and down-regulate the expressions of SREBP-1c and SCAP in liver tissue of type two diabetes mellitus. Compared with the control group, there were significant differences in relevant protein expression (<0.05, <0.01). This indicates that the inhibition of SREBP-1c and SCAP expressions may be the hypolipidemic mechanism of Coptidis Rhizoma on type 2 diabetes mellitus. The results also showed that C. deltoidea has a better efficacy in lipid elimination, but a weaker hypoglycemic effect against C. chinensis.
