UNASSIGNED
Plant-based natural extracts cure several diseases in human. However, the extract of Psidium guajava leaf is not yet evaluated on changes of lipid profile in hepatic disease affected rats.
UNASSIGNED
The present study was aimed to evaluate the mitigation effect of the ethanolic extract of P. guajava leaf and its isolated quercetin fraction on hepatotoxic rats.
UNASSIGNED
Carbon tetrachloride (CCl4) was injected to rats for hepatic disease induction and silymarin drug was used as positive control to compare plant ethanolic extract. The lipid profiles were assessed in both plasma and liver tissue of diseased and control rats.
UNASSIGNED
Levels of total cholesterol, triglycerides, free fatty acids, phospholipids, and low-density lipoprotein cholesterol were increased and the level of high-density lipoprotein cholesterol (HDL-C) was decreased in CCl4-induced hepatotoxic rats. The treatment of P. guajava (100, 200, and 300 mg/kg, bw) and isolated quercetin fraction (20 mg/kg, bw) doses decreased the elevated levels of all these parameters in diseased rats and restored the normal concentration of HDL-C.
UNASSIGNED
The results of the present study concluded that the P. guajava leaf and its isolated quercetin fraction can significantly regulate lipid metabolism in CCl4-induced hepatotoxic rats and decrease the disease rate.
CONCLUSIONS
Psidium guajava leaf extract reduces the hepatotoxicity and disease rate in ratsQuercetin fraction of leaf extract significantly regulates lipid profile in hepatic diseased rats. Abbreviations used: CCl4: Carbon tetrachloride; FFA: Free fatty acids; HDL-C: High-density lipoprotein cholesterol; LCAT: Lecithin cholesterol acyltransferase; LDL-C: Low-density lipoprotein cholesterol; PL: Phospholipids; TC: Total cholesterol; TG: Triglycerides; VLDL-C: Very low-density lipoprotein cholesterol.
