Combined effects of Diospyros lotus leaf and grape stalk extract in high-fat-diet-induced obesity in mice.

The aim of this study was to investigate the combined effects of Diospyros lotus leaves extracts (DLE) and Muscat Bailey A grape stalk extracts (MGSE) in obesity induced by high-fat diet (HFD) in mice. The mice were fed with HFD and orally administered daily with DLE, MGSE, a mixture of DLE and MGSE, and Garcinia cambogia extract over a period of 16 weeks. The results revealed that daily administration of DLE and MGSE mixtures markedly prevented HFD-induced weight gain, plasma lipid profile, hepatic steatosis, hepatic fibrosis, diabetic symptoms, and the risk of developing cardiovascular diseases. Also, DLE and MGSE mixtures administration greatly prevented oxidative stress and liver toxicity. The combined effects of DLE and MGSE mixtures were higher than effects of the single extracts and of G. cambogia, a plant known for its anti-obesity effects. In summary, these findings demonstrated that DLE and MGSE mixtures, exhibit anti-obesity activity in HFD-fed mice.
