Euphorbia humifusa Willd (Euphorbiaceae) is a functional raw material with various pharmacological activities. This study aimed to validate the inhibitory effect of Euphorbia humifusa extract (EHE) on adipocyte differentiation in vitro and in a high-fat-diet (HFD)-induced mouse model to evaluate the E.a humifusa as a novel anti-obesity and lipid metabolism enhancer agent. EHE effects on obesity and lipid metabolism were assessed in HFD-induced obese mice after 4-week treatments. Results were compared among four treatment groups (n = 7/group): low fat diet (LFD), high fat diet (HFD), and HFD-induced obese mice treated with either 100 or 200 mg/kg/day EHE (EHE100 and EHE200, respectively). EHE (50 to 200 μg/ml) and quercetin (50 μg/ml) significantly reduced 3T3-L1 preadipocyte differentiation (p < 0.001), in a concentration-dependent manner. EHE affected lipid metabolism, as evidenced by changes in serum lipid components. The HFD-EHE100 and HFD-EHE200 groups exhibited significantly (p < 0.05) reduced triglycerides (TG, 97.50 ± 6.56 and 82.50 ± 13.20 mg/dL, respectively) and low-density lipoprotein-cholesterol (LDL-c: 40.25 ± 4.99 and 41.25 ± 6.36 mg/dL, respectively) compared to the HFD group (TG: 129.25 ± 19.81 mg/dL; LDL-c: 51.75 ± 11.59 mg/dL). Haematoxylin and Eosin (H&E) and Oil red O staining showed that EHE markedly reduced lipid accumulation and inhibited lipogenesis in the liver. Interestingly, EHE significantly (p < 0.01) reduced the expression of adipogenic transcription factors in liver tissue. Our results indicated that EHE has the potential to be a therapeutic agent for addressing obesity and lipid metabolism.
