THE POTENTIAL EFFECT OF TIGERNUT OIL ON SOME HAEMATO-BIOCHEMICAL BLOOD INDICES IN MALE ALBINO RATS

Hanaa Ali Hassan.




Abstract

The present work which is considered as an experimental study aimed to assess the effect of tigernut (Cyperus esculentus) oil on some haematological and biochemical parameters in normal adult rats to evaluate tigernut oil supplementation and its possible use as a therapeutic agent. Tigernut oil was extracted from tigernut tubers and injected intraperitoneally to rats at two different doses (0.1 ml/Kg bw and 0.5 ml/Kg bw) for successive six weeks. Some haematological and biochemical parameters were assayed. The studied haematological parameters including RBCs, WBCs and platelets counts, as well as haemoglobin, haematocrit, MCV, MCH and MCHC values revealed a positive change in rats treated with tigernut oil particularly at the higher tested dose (0.5 ml/Kg bw). Concerning the biochemical studies, the results revealed that the treatment with tigernut oil reduced serum glucose level at the two studied doses. Also, the data of liver and kidney functions including serum ALT and AST enzymes activity, as well as total bilirubin, urea, and creatinine levels recorded positive changes in rats that treated with tigernut oil and the changes were dose-dependent especially in serum total bilirubin. Moreover, serum total cholesterol showed significant decrease while serum HDL-c and HDL-c/ Total cholesterol ratio revealed significant increases at both treated doses of tigernut oil. However, the results of serum metals (sodium, potassium, calcium, and magnesium concentrations) showed non-significant change, while serum iron concentration was significantly increased. In conclusion, these data clarified that tigernut oil exhibits a good agent for maintenance and improvement the haemato-biochemical parameters in healthy rats. Thus, the supplementation with this oil has benefits and safety. Furthermore, it is hoped that further work goes in this direction to high light the potential use of tigernut oil for overcoming some healthy problems.

Key words: Tigernut (Cyperus esculentus) oil – Haemoto-biochemical parameters – Rats
