ABSTRACT
The effect of ethanolic leaf extract of Solanum torvum on the lipid profile of monosodium glutamate – treated rats was investigated. Twenty (20) adult male Albino wister rats were used for the analysis. They were divided into four (4) groups of five rats each. Group I was the normal group and was fed with normal feed and water. Group II was the test control administered with (0.5g/kg) of monosodium glutamate, feed and water, Group III was administered with (250mg/kg) of the leaf extract and 0.5g/kg of monosodium glutamate, and Group IV administered with (500mg/kg) of the leaf extract and 0.5g/kg monosodium glutamate. The rats were housed and subjected to the feed, leaf extract, MSG and water, for 28 days after which they were sacrificed, after an overnight fast, and blood collected by cardiac puncture and used for serum preparation for subsequent analysis of the various parameters. There was no significant change (p > 0.05) in triacylglycerols and VLDL cholesterol in all the groups when compared with the normal and test groups. However, there were significant decreases (p < 0.05) in serum total cholesterol, HDL – cholesterol, and LDL – cholesterol in group 3 and group 4 when compared with the normal and test control. These shows that Solanum torvum leaf extract at the result doses administered may be able to modulate the lipid profile thereby ameliorating the effect of monosodium glutamate.

CHAPTER ONE
INTRODUCTION
1.1 Background of the Study Solanum torvum is commonly known as turkey berry is native and cultivated in Africa and West Indies (Adjanohoun et al., 1996). The fruits and leaves are widely used in Cameroonian folk medicine. It also occurs commonly in the moist farms of India. The fruits of S. torvum are edible and commonly available in the markets. They are utilized as a vegetable and regarded as an essential ingredient in the south Indian population’s diet. A decoction of fruits is given for cough ailments and is considered useful in cases of liver and spleen enlargement (Siemonsma et al., 1994). The plant is sedative and diuretic and the leaves are used as a haemostatic. The ripened fruits are used in the preparation of tonic and haemopoletic agents and also for the treatment of pains (Kala 2005).
