Studies on metabolism of total terpene ketones from Swertia mussotii with human intestinal bacteria / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the metabolism of total terpene ketones from Swertia mussotii with human intestinal bacteria.</p><p><b>METHOD</b>Total terpene ketones were incubated with human intestinal bacteria under an anaerobic environment and at 37 degrees C. The metabolites were extracted by ethyl acetate processing, detected by HPLC-DAD method. A qualitative analysis was made for its metabolites by HPLC-MS.</p><p><b>RESULT</b>Eight metabolites were detected from total terpene ketones from S. mussotii with human intestinal bacteria, and two of them were preliminarily identified as gentianine and mangiferin aglycon.</p><p><b>CONCLUSION</b>Total terpene ketones can be metabolized with human intestinal bacteria, which provides basis for experiments on the metabolism process total terpene ketones from S. mussotii with human intestinal bacteria.</p>
