Studies were undertaken on the effect of 50mg/kg each of the aqueous fruit extract of Solanum macrocarpum, α-solanidine, (a steroidal glycoalkaloid found in the Solanaceae), three antihyperlipidaemic drugs namely nicotinic acid, simvastatin and cholestyramine) on forty two (42) rats made hyperlipidaemic by treating them with 400 mg/kg triton-X for 7 days. The rats were divided into 7 groups of 6 rats each. At 24hrs, 48hrs and 72hrs respectively, the rats in each group were humanely sacrificed and blood samples collected for analysis of total lipid profile [total cholesterol, triglyceride, high density lipoprotein-cholesterol (LDL-C) and low density lipoprotein cholesterol (LDL-C)]. Very low density lipoprotein cholesterol (VLDL-C) and atherogenic index (A.I.) were also calculated. Faecal samples were also collected, homogenized and extracted with chloroform/methanol in the ration 2:1 for faecal cholesterol determination. The extract, α-solanidine and the three hypolipidaemic drugs all significantly decreased (P<0.05) LDL-C and triglycerides at 48hrs and 72hrs, whilst HDL-C increased significantly (0.05) throughout the period of study (24hrs, 48hrs and 72hrs). There was no change in total cholesterol (P>0.05) for all the five substances tested throughout the period of study, whilst VLDL-C and A.I. decreased significantly (P<0.05) at 24hrs, 48hrs and 72hrs. These results imply that under the condition of this study, the aqueous fruit extract of S. macrocarpum compared favourably with α-solanidine and the three hypolipidaemic drugs in reducing the risk of development of heart diseases.
Key words: Solanum macrocarpum, faecal cholesterol, total lipid profile, VLDL-Cholesterol, atherogenic index, α-solanidine, hyperlipidaemic rats, hypolipidaemic drugs.
