Role of flower extract in preventing hyperlipidemia and liver lipid peroxidation in male mice

Abstract

: Hyperlipidemia leads to coronary artery disease. Although statins are used conventionally, they are often associated with side effects. It has now been attempted to study the role of flower (MOF) extract in the regulation of tyloxapol-induced hyperlipidemia and tissue lipid peroxidation (LPO) in male mice.Six groups of animals were taken. Group I acted as control and group II, receiving tyloxapol (300 mg/kg, single dose on 14 day) served as hyperlipidemic control. Group III received simvastatin (200 mg/kg), while group IV, V and VI received MOF extract at 400, 200 and 100 mg/kg every day respectively for 15 days. These four groups (III- VI) also received same amount of tyloxapol on 14 day. On day 16 changes in the serum total cholesterol, triglycerides, high-density lipoprotein, low-density lipoprotein and very low-density lipoprotein; hepatic LPO, super oxide dismutase, catalase, glutathione peroxidase and histological changes in liver were analyzed. Total phenolic and flavonoid contents were also estimated. The in-vitro antioxidative property was checked through DPPH and HO assays.: Results showed significant reduction in all the serum lipids except HDL, which was increased in MOF treated hyperlipidemic mice, with the parallel decrease in hepatic LPO and increase in antioxidants. Histological studies also showed reduction in hepatic damage with the pre-treatment of MOF. However, the most effective dose was found to be 400 mg/kg of MOF. : We suggest that flower extract may ameliorate hyperlipidemia with antioxidative benefits.
