Article Synopsis
- Purpose of the study included assessing the antioxidant activity of Pycnogenol, its effects on lens integrity in organ culture, and its potential to reduce damage in diabetic cataract models.
- Various methods such as antioxidant assays and lens incubation with glucose were employed, alongside monitoring diabetic rats over 12 weeks to evaluate the impact of Pycnogenol.
- Results showed that while Pycnogenol exhibited antioxidant properties in vitro, it also caused lens opacity and damage at certain concentrations; however, in vivo, it improved lens conditions in diabetic rats and reduced glycation of proteins.
Hypericin is the ingredient used to standardize the popular over-the-counter antidepressant medication St. John's Wort. Because hypericin readily produces singlet oxygen and other excited state intermediates, it is a very efficient phototoxic agent in the eye that can potentially induce the development of the cataract photooxidative mechanism.

Phenols were measured colorimetrically using an oxidation-reduction reaction with Folin-Ciocalteu reagent and catechin as the standard. The order of phenol concentration was ales > lagers > low calorie > nonalcoholic.
