AS extract reduces HFD-induced obesity in rats.

<p>Rats were randomly divided into five groups: normal control, HFD model, and HFD with AS extract (100, 300, or 900 mg/kg). The extract was intragastric administered for 6 weeks. (<b>A</b>) Food intake per rat was recorded six times a week. (<b>B</b>) Food efficiency ratio was calculated as body weight gain divided by food intake. (<b>C</b>) Change in body weight was measured six times a week. (<b>D</b>) Body weight gain measured in a given week was subtracted from the weight in the previous week. Values are expressed as mean ± SE (n = 30). Significant differences were observed between normal and HFD groups. *P < 0.05, **P < 0.01, ***P < 0.001 vs. normal group; ^#P < 0.05, ^##P < 0.01, ^###P < 0.001 vs. model group.
