Antiobesity Effects of the Combined Plant Extracts Varying the Combination Ratio of Phyllostachys pubescens Leaf Extract and Scutellaria baicalensis Root Extract

الملخص EN

The antiobesity effects of several different combinations of extracts (BS) prepared from two plants, Phyllostachys pubescens leaf (bamboo leaf: BL) and Scutellaria baicalensis root (SB), were investigated using a high fat diet (HFD) induced obese mouse model.

In order to find the most effective mixture among the mixtures of the two plant extracts, experimental preparations were made by combining BL and SB by different proportions of 3 : 1 (BS31), 2 : 1 (BS21), 1 : 1 (BS11), 1 : 2 (BS12), and 1 : 3 (BS13).

Body weight, weight of adipose tissues, size of adipocytes, levels of glucose, leptin and adiponectin, and lipid profile in serum, and fat accumulation in liver were investigated.

We have found that BS21 is the most effective in antiobesity among the five mixtures investigated, indicated by reduction in body weight gain, total mass of adipose tissue, and the size of adipocyte.

In addition, BS21 has shown to be beneficial in serum lipid profile, levels of glucose, leptin, and adiponectin in serum, and fat accumulation in liver.

By chromatographic separation of BS21, the two maker compounds, isoorientin and baicalin, were identified and quantified for the standardization of BS21.
