Abstract
The leaf of Crataegus pinnatifida (Rosaceae) is commonly consumed either raw or cooked to improve digestion and promote blood circulation in China. To investigate the regulation effects of it on glucose and lipid metabolism, the flavonoids fraction was prepared and analyzed by HPLC and LC-MS. In vivo, at doses of 250 and 500 mg/kg, the flavonoids fraction showed inhibitory effects on TG and glucose absorption, accelerating effects on gastrointestinal transit but no effect on gastric emptying. In vitro, treatment of 3T3-L1 preadipocytes with 30 μg/mL flavonoids fraction significantly suppressed the accumulation of TG and free fatty acid. It also suppressed the gene expressions of C/EBPα, PPARγ, SREBP 1c, aP2 and adiponectin but did not affect that of leptin. C. pinnatifida leaf may be useful for type 2 diabetics and hyperlipidemics as a foodstuff.Entities:
