Inhibition of Aldose Reductase and Anti-Cataract Action of Trans-Anethole Isolated From Foeniculum Vulgare Mill. Fruits

Food Chem. 2012 May 1;132(1):385-90. doi: 10.1016/j.foodchem.2011.11.005. Epub 2011 Nov 10.


Foeniculum vulgare fruits are routinely consumed for their carminative and mouth freshening effect. The plant was evaluated for aldose reductase inhibition and anti-diabetic action. Bioguided fractionation using silica gel column chromatography, HPLC, and GC-MS analysis revealed trans-anethole as the bioactive constituent possessing potent aldose reductase inhibitory action, with an IC50 value of 3.8μg/ml. Prolonged treatment with the pet ether fraction of the F. vulgare distillate demonstrated improvement in blood glucose, lipid profile, glycated haemoglobin and other parameters in streptozotocin-induced diabetic rats. Trans-anethole could effectively show anti-cataract activity through the increase in soluble lens protein, reduced glutathione, catalase and SOD activity on in vitro incubation of the eye lens with 55mM glucose. Trans-anethole demonstrated noncompetitive to mixed type of inhibition of lens aldose reductase using Lineweaver Burk plot.
