Abstract:
Objective To study the effects of total extracts of Averrhoa carambola L.( Oxalidaceae ) roots ( TEACLR ) in hyperlipidemia rats. Methods Sixty SD rats ( male and female in half ) were subjected to induction of hyperlipidemia by high -fat diet for established hyperlipi-demia rat model and were divided into the following groups:blank group, model group, positive control group ( simvastatin 2.5 mg? kg-1? d -1 orally) , TEACLR high, middle and low doses groups.Hyperlipidemia rats were treated with TEACLR, at doses of 1200, 600 and 300 mg? kg-1? d-1 for 5 weeks by gavages, respectively.After 5-week of treatment with drugs, blood sample and liver were collected for determi-nation.Results In contrast to the model group, TEACLR could reduce the contents of cholesterol, triglyceride, low-density lipoprotein, alka-line phosphatase in rat serum and liver malondialdehyde reduced obvious-ly [ ( 2.48 ±0.43 ) , ( 0.86 ±0.44 ) , ( 0.86 ±0.43 ) mmol? L-1 and (165.55 ±71.71 ) U? L-1 , ( 1.38 ±0.42 ) nmol? prot-1 , respective-ly] .The level of high -density lipoprotein and glutathione elevated evidently [(1.67 ±0.32)mmol? L-1,(3.43 ±0.78)nmol? prot -1]. Liver coefficient was significantly lowered ( 2.92 ±0.03 ) .TEACLR middle dose group could reduce the contents of alanine aminotransferase(ALT) and aspartate aminotransferase(AST) obviously[(38.91 ±10.47),(99.91 ±30.74) U? L-1 ].TEACLR high dose group could increase the contents of superoxide dismutase evidently(24.44 ±3.13) nmol? prot -1 .Comparison with blank group and positive control group, there was no significant difference in TEACLR middle dose group.Conclusion TEACLR is proven to be able to decrease the level of hyperlipidemia markedly, which might be used as an effective therapeutic agent for hyperlipidemia and fatty liver.
