Aim: This study sought to investigate the hypoglycemic and hypolipidaemic effect of methanolic extract of Corchorus olitorius leaves in Albino rats.
Methods: Fresh plants of C. olitorius were harvested from the Institute of Agricultural Research and Training, Ibadan. The leaves were dried and extracted using soxhlet apparatus and methanol as the solvent. The methanol was evaporated in a rotary evaporator at 35°C with a yield of 2.17 g which represents a percentage yield of 8.68%. Ten adult male albino rats with body weight between 100 and 120 g were used for this study. They were randomly divided into two groups of five rats each. Animals in group 1 were administered saline solution while those in group 2 were administered C. olitorius extract. The animals were exposed to the extract and saline solution at a dose of 3 mL per 100 g body weight 12 hourly via oral route of administration. After fourteen days of administration, the animals were fasted overnight and anaesthetized using diethyl ether. Blood samples were collected by cardiac puncture. Fasting blood sugar and lipid profile were determined using standard methods.
Results: C. olitorius leaves was observed to significantly lower fasting blood sugar, total cholesterol, LDL-cholesterol and triglyceride but increased HDL-cholesterol and HDL/LDL-cholesterol ratio significantly when compared to those of the control group at p<0.05.
Conclusion: The result of this study implies that C. olitorius leaves are of significant health importance as far as hyperglucosemia and hyperlipidaemia is concerned. It could also be exceedingly helpful in the control of obesity and hypertension. This pharmacological study is a useful tool for further drug development from the natural plant products.
