Effect of (L.) Juss. ex Kunth in a Murine Model of Metabolic Syndrome.

Metabolic syndrome is a constellation of abnormalities related to insulin resistance with an unfortunately high prevalence worldwide. (L.) Juss. Ex Kunth. is a well-known medicinal plant that has been studied in several biological models related to diabetes mellitus. The aim of this study was to evaluate the effects of on a hypercaloric diet-induced metabolic syndrome model. An organic fraction obtained using liquid-liquid separation from the hydroalcoholic extract of and four subfractions of this organic fraction were administered for ten weeks to C57BL6J male mice previously fed with a hypercaloric diet. The hypercaloric diet caused changes in glucose levels (from 65.3 to 221.5 mg/dL), body weight (31.3 to 42.2 g), triglycerides (91.4 to 177.7 mg/dL), systolic (89.9 to 110.3 mmHg) and diastolic (61.6 to 73.7 mg/dL) blood pressure, and insulin resistance (4.47 to 5.16). Treatment with resulted in improvements in triglycerides (83.4-125.0 mg/dL), systolic blood pressure (75.1-91.8 mmHg), and insulin resistance (4.72-4.93). However, the organic fraction and hydroalcoholic extract produced a better response in diastolic blood pressure (52.8-56.4 mmHg). Luteolin, apigenin, and chrysoeriol were the major constituents in the most active subfractions. Treatment with , particularly a luteolin-rich organic fraction, achieved an improvement in metabolic syndrome alterations.
