Anti-diabetic and hypolipidemic effects of Cinnamon cassia bark extracts: an in vitro , in vivo , and in silico approach.

The present investigation was aimed to study the anti-diabetic and hypolipidemic potential of Cinnamon cassia (Lauraceae family) bark in streptozotocin (STZ)-induced diabetic rats. The preliminary phytochemical analysis (hexane, petroleum ether, chloroform, ethanol, methanol, and aqueous extracts), GC-MS analysis (ethanol), in vitro (aqueous, ethanol and methanol), in vivo (ethanol) and in silico anti-diabetic activity with hypolipidemic effect of C. cassia bark was analysed. The ethanolic extract of the C. cassia bark has a fine inhibitory activity than the aqueous and methanolic extract. Out of 20 different compounds identified, seven compounds were biologically active, and 9-octadecenoic acid has highly interacted with PPARα/γ in docking studies. The levels of diabetic markers, enzymes, and lipid profiles were altered in STZ-induced rats, but after the treatment of C. cassia , the levels were returned to the normal. The study may prove the ethanolic extract of C. cassia has a powerful anti-diabetic and anti-hyperlipidemic activity.
