Background: Choline is an essential lipotropic nutrient for regulating fatty acid synthesis and hepatic lipid mobilization. Deficiency of choline causes fatty liver leading to dysregulated liver function. Objective: To investigate the lipotropic activity of the proprietary herbal formulation (PHF) containing Acacia nilotica and Curcuma longa. Materials and Methods: Fatty liver disease was induced in Wistar rats by feeding methionine/choline-deficient (MCD) diet for 4 weeks. Animals were concurrently treated with PHF (at 50, 100, 200, and 400 mg/kg rat body weight/day) for 4 weeks. Methionine/choline-sufficient (MCS) diet-fed rats were used as control. Serum biochemistry and liver parameters were determined at the end of experimental period. Further, anti-lipogenic and lipolytic activity of PHF extract was studied in HepG2 cells. Results: Rats fed with MCD diet, showed significant increase in liver lipids, triglycerides, cholesterol, thiobarbituric acid reactive substance, and serum alanine transaminase (ALT) and decreased serum triglyceride level compared to MCS diet-fed rats indicating significant fat accumulation and liver damage. PHF treatment significantly decreased the liver lipids, triglyceride and serum ALT compared to MCD diet-fed rat. Histological evaluation revealed the restoration of hepatic architecture after PHF treatment. In in vitro studies, the PHF extract decreased the oleic acid induced fat accumulation in HepG2 cells. Conclusion: The study demonstrated the lipotropic effect of PHF evident from decreased fat accumulation and antilipogenic activity. These data suggests that PHF could be a potential supplement for preventing fatty liver. [ABSTRACT FROM AUTHOR]
